Knowledge Lecture why winter fuel consumption higher than in summer

To understand the reasons, the first principle from the start with the engine cooling. Needs engine work, a normal temperature environment (80 to 90). If the temperature is too high, the engine cooling system can automatically change the cooling water circulation, increase the heat, remove excess heat; Conversely, reducing the cooling water circulation to maintain the necessary temperature. To achieve changes in main components of automatic cycle is the engine temperature sensor sensor, thermostat valve thermostat and magnetic fan.
Cold starts, the magnetic fan is stopped, the thermostat valve is also in the off state, the engine coolant in the engine water jacket only in small cycles, easy to heat, while the computer by the temperature sensor of the temperature index effect will be issued to increase fuel injection, increase the idle valve opening instruction to improve the engine speed, will help allow the engine to heat up quickly; temperature is normal, fuel injection and idle speed valve opening are back to normal. When the temperature exceeds 80 to 90 degrees (each car is slightly different), the thermostat valve is opened, the engine water jacket inside the coolant flowing through the radiator through the radiator thermostat valve big loop through the traffic generated by the air flow away a lot of calories to maintain the normal coolant temperature. If speed is not slow or even stop, but turn off, there is no flow of air to help heat the engine will quickly heat up, then give directions to the magnetic sensor to help start the radiator cooling fan.
Winter, the engine is warm and not need heat! Winter due to the impact of air flow, engine temperature is not easy to remain at 80 to 90 degrees, the engine will increase the amount of fuel injection and ignition advance angle changes to maintain the temperature, the thermal efficiency of gasoline at the same time much less than the hot days. In addition, in order to maintain the normal speed you will unwittingly increase the throttle opening. These will increase fuel consumption.
Come to talk about whether the costs to open hot oil problem. The answer is yes - open hot air definitely increase fuel consumption!
In order to maintain the temperature of the engine in winter, mostly in small cycles; and when you open the hot air, the cold air rapidly flowing through the heater core inside the surface, is actually cooling for the engine to increase an efficient circulatory system inside the radiator! Its role can be imagined.
All in all, winter is certainly higher fuel consumption than usual, even more than the summer air conditioning is also high; hot air to open a more wide open than increasing it.

Knowledge of automotive repair high-speed oscillating Troubleshooting

A high-speed runout, there are two cases, one with increased speed, gradually strong runout; second, appeared at a high speed oscillating. And jitter caused by the steering wheel, set up the first drive axle, front wheel increases security plug block, start the engine and gradually change into high gear, the drive wheels to shimmy speed. If the body and steering wheel are now shakes, was caused by runout transmission. Because at this front-wheel front axle in a quiescent state, if the runout speed up the final test, the car does not appear jitter, the runout of the car before the bridge part of the system because there is a fault;
Second, check the front wheel toe angle and the positioning of compliance requirements, such as inaccurate should be adjusted;
Third, set up test before the bridge turn the wheel, check the wheel balance and static deformation of the tire is too large. Necessary, change wheels comparison test;
Fourth, check the front axle, the frame is deformed, check the shaft is bent, should be made conditional shaft balancing;
5, check the stiffness of the front leaf spring, shock absorber and spring bracket the performance of loose rivets, etc., do not meet the performance should be replaced.

Newbie car knowledge: Do not let the faster car the more open

Readers Miss Lee: I am almost birthday, my father bought a car for me. Driving just graduated last month, I took this, but the overall feeling of the master to teach the skills are not enough, many in the school car I have not touched the new things are tense, more open feel faster car, do not know how.
Answer: Most people learn in driving school is a manual transmission, while many people consider when buying a car to use the convenience and saving often choose Automatic.
Automatic transmission driving the car usually only need to gear hanging in the "D" on, you can rest assured the road. Vehicle speed automatic transmission can be according to the situation with the throttle automatically block rose from a 4 block. However, almost all of the cars are equipped with automatic "limit stop" or "1", "2", "3", "4" and some other gear, its function is to limit the automatic transmission's shift timing to achieve the purpose of engine speed continue to improve, help the engine power and torque output. If the link to "3", the highest rise 3 can automatically block; linked to the "2", you can block up to 2; if linked to "1" means that transmission can only work in one block.
Use "limit stop" special feature that gives a feeling similar to driving a manual transmission car, the car's dynamic performance more easily. Such as the need to accelerate Lian Fei car or uphill, it will be "D" block into a "3" block, you can make automatic car ubiquitous "throttle lag" feeling can be improved significantly. Downhill, due to its own gravity to drive the car, the car will run faster and faster. If you hang in the D block, and light throttle, the transmission will automatically up to high gear, so the speed will be faster. If you do not want such a result, consider hanging the "3" block or "2" block. Broadcast to share the space and striving to broadcast the first person microblogging microblogging recommended

Automotive Knowledge: rapid dissemination of open hot car smell

People buy a new car is a happy thing, but just that new car just to renovate the room just like there are always some people uncomfortable smell the odor. In each one before passing the car factory, manufacturers have been a strict odor checks to ensure that every one car to reach the hands of users able to meet the body odor of acceptable limits, so that the health of occupants will not be affected. However, the new car smell car always needs some time to gradually eliminate some families buy a new car after a long period of time, will try to avoid pregnant women and children traveling, we can see it for the new car smell concerns.
Instead of passively waiting for the new car smell in the course of gradual decay, as some small way to learn driving away those annoying odor! Now remove the new car smell in many ways, such as the 4S shop to accept the new car in addition to the professional care and taste, photocatalyst odor, turn on the water in the car peel, put charcoal to absorb odor and so on, but takes some effort, some of these approaches have The effect is not obvious. Owners bother to try the easiest way --- the use of the car itself features some hot air, the smell quickly distributed to help the car, a few more times, the new car smell can loose faster!
New car smell come from?
Car leather or fabric seats, plastic parts, and after the newly acquired car mats, seat covers and other items will bring the new car smell. Leather seats with a waterproof, breathable, easy to clean, etc., but the cortex itself is relatively heavy odor emitted, and difficult to remove. The new fabric seat will be with some of the odor, but odor fabric materials are generally relatively light, smell is not so strong. Plastic is widely used in automotive interior materials, such as large-scale use of materials, plastic materials distributed by the new car smell is out of most. In the high temperature exposure, some low-quality plastic odor contain substances harmful to human health directly, in the purchase of new car owners should be carefully distinguished. In addition to these materials used in car interiors emit odor, car air conditioning in the initial use will bring out some of the odor. Individual owners of the respiratory tract are particularly sensitive to even use air conditioning because of the new car feel sore throats.
In addition to smell the former should do first?
Car after car of the people mentioned most think of first is to take care of their car, so many owners buy a new car for some time still preserved "the original produced" plastic protective film, I feel this way allows the state to keep car longer, and can let the plastic protective film to protect the seats and other interior. These new cars sold in plastic protective film can indeed protect the car before the parts, but after buying a new car once used, they should promptly tear up, so as not to affect the car seat parts in a timely manner harmful emissions. Otherwise the plastic film has been "clutching" the new car's gas distribution affected by the time the car smell will stay longer.
Many new car owners in a hurry to add that many of the interior, such as purchase floor mats, seat covers, car perfume seat, and so on. If these items do not pay attention to check the quality of choice, will add to the car smell. In particular, some low-quality plastic mats, not only did not play a waterproof interior, decorative features, rather than the car itself is more important odor components. Referring to new car owners do not have to hurry to add interior, new car smell gradually faded, you can pick some of the superior quality of the interior Dress up your car.
In addition to taste The easy way is what?
New car there are many ways in addition to taste, not only to the 4S shop professionals can take care of, you can also use fruit, bamboo charcoal to take away car smell. Leather car seat, plastic parts and some glue comes out of the harmful gases evaporate slowly at room temperature, but when the inside temperature reached 30 ℃ or higher, these gases will accelerate the evaporation. Using this principle, we can not open a hot car to car, take the initiative for the interior heating, so that harmful gases inside the active volatilization temperature reaches the optimum temperature to accelerate the evaporation of harmful gases. Open hot air should pay attention to the enclosed interior space, for some time to open the car door windows to help air out. Such an approach is both effort and money, they do not cost the owners more time. The use of fragmented free time to open a few more hot air, so use this method more than cycle a few times, we can accelerate the car smell of the discharge. Note that, with smell of exhaust hot air to accelerate the car does not mean the car placed in the exposure to the sun, the sun can also play a proper taste of hot air in addition to the effect, but prolonged exposure to the sun is not desirable, should be avoided.
Other methods
Window ventilation
When driving the new car smell is almost unavoidable, to minimize harm to human body odor, we recommend that owners try to avoid driving in the windows closed and the inner loop. Open windows for fresh air ventilation into the car is the easiest way, but this approach on the new car smell of the discharge does not play a big role. Some windows will stop when the owner leaves a small gap, this approach is used in a safe parking environment is more appropriate.
In addition to taste fruits and vegetables
Many owners of new homes will be renovated after the odor used in the car on the way. Grapefruit peel, orange peel, pineapple skin, lemon, onion and so on fruits and vegetables are handy. This method is simple and easy to operate, and low-carbon environment, ideal for love-it-yourself owners friends. But note that, put them in the car when the need for regular and timely replacement of skin, avoid fruits and vegetables in the closed environment inside the long-term spoilage. Some owners put in the car full of fruit should be avoided or placed directly on the center console near the windshield, so as to avoid potential hazards in the road.
Placed activated carbon, decoration deodorant
Purchase the efficacy of activated carbon adsorption of formaldehyde is removed to place the new car smell in the car a big way. New car smell can be the size of the owner to determine the number of activated charcoal placed in the car, simple and convenient. Placed in the car owners have a professional fitting deodorant, as the treatment of newly renovated rooms to handle the new car smell the same.
Professional air purifier odor
If the car owner is not very understanding of the method in addition to taste, to the 4S shop car can be a professional staff to take care of. 4S shop now has to use a professional negative ion air purifier in addition to taste, odor photocatalyst method, every 1-2 months to maintain once the new car smell removal effect is obvious.
In addition to taste Mistakes
In addition to the focus of the new car smell is the smell inside the car as discharge, because they smell more or less harmful to human health impact. If you use perfume, air fresheners to remove the new car smell, so not only did not let the car's harmful gas emissions, but will make more of their unwanted chemicals inhaled fragrance. Perfume and deodorants just played a cover up with a more intense flavor effect of the new car smell, new car smell is not for the elimination of any help, recommended that owners do not use this runs counter to the approach.

Summer car prone to spontaneous combustion in prevention / fighting / escape Detailed knowledge

Scorching sun baked people uncomfortable, if the car is really a fire you know how to deal with it? Car fire extinguisher do you have? You know the common sense fight car fires do? If your vehicle is on fire you know how to escape it? You know what the car should be equipped with it? You know what the car could get you into hidden crisis?
Fire articles
Response to spontaneous combustion, 3 minutes to fire, not eliminate the Run
Car fire, rescue or escape what is, depending on the case may be, in general, private car within 3 minutes of the fire may self-extinguish if burning more than 3 minutes, too dangerous, or abandoned the vehicle and escape better. Owners in driving the process, once the smell of coke smell or see smoke, immediately in a safe place to park and turn off the power, it is very important because it can cut off the ignition and fuel injection to reduce the risk of fire or reduce the damage. Then tighten the handbrake, leave the vehicle, identify the cause. Found after the fire, under the circumstances to take the next step.
Small fire quickly destroyed
Vehicle fires are usually started from a part of the spread of fire and then, if found early, the fire was limited to small parts of the fire, and only minor smoke, this time with their car fire extinguishers generally can defuse the crisis. If there is no fire extinguisher, to help others, and use blankets, sand to cover up the source of fire may be extinguished.
Some method in the fire
If the engine compartment has begun to smoke and flames have jumped out from the gap, then the fire has developed to a more serious level, do not open the hood to prevent air convection increase fire intensity. Then lock wrench can be opened to allow the hood missed a crack, and then entered, and spray fire-extinguishing agent, be stopped until there is no smoke. Then to open the hood, to clean-up.
Ran to the fire
Do not expect your little car fire extinguishers to put out the fire, no more than 3 minutes if the fire can be effective, then the car should have at this time is the whole body on fire. Single-handedly pull the situation has been difficult, and quickly leave, timely evacuation of passengers and onlookers or the kind help of non-professionals to avoid injury.
In prevention articles
Precautionary measures
Maintenance of safety first random modification may be fatal when the car is taken into account in the design of the car fire prevention, such as using fire-retardant materials, devices, and so set off the fuel, but because of improper maintenance, modification, or random factors that cause accidents and other reasons, the car use, may still fire. To take preventive measures, we need to know some car knowledge.
Maintain
Anti-oil containers and oil system pipe rupture or leakage caused by loose pipes easily cause a fire, if the vehicle is a long period, resulting in the aging pipeline cracks, or improper use and maintenance, oil changes, such as chaos, or loose joints may resulting in fuel leakage if they encounter a fire or heat the oil may be burned, causing a fire.
Some vehicle's engine was decorated cover up, to check whether the aging pipeline or loose connections is not easy, in strict accordance with instructions maintenance or replacement of fuel hoses necessary.
Detailed examination
Leakage power is more complex vehicle electrical systems, electrical lines, clouds, auto electrical systems under normal circumstances, less fire hazard, but may be modified at random by the driver, for example, the change of non-standard high-power audio, illegal operation or circuit fault caused fire. For example, if the battery cable loose or damaged wire insulation aging, moving bumps is likely to result in vehicle wiring and the wiring, ignition wiring short circuit with the body, may also cause a fire. Car alternator regulator and other components if the failure may also cause a fire.
Do not carelessly leave troubles
If carelessness, will throw the ashes of the cigarette box on the throw rug in the car, or stay in the dashboard lighter let the sun exposure, may cause a fire. Not only lighter, refreshing, anti-mosquito agents are afraid of high-temperature high-pressure filling gas, the summer temperature inside the vehicle in direct sunlight can be as high as fifty or sixty degrees, so that they can easily explode. In addition, many farmers in the summer sun straw and other items on the road, if wrapped around the car's exhaust pipe, exhaust pipe heat may also ignite the flammable hay.
Escape articles
Escape the knowledge, the occurrence of dangerous situations, the first out of the bus for the wonderful
Once while driving smelled coke smell or see smoke, stop immediately in a safe place nearby, and turn off the power, tighten the hand brake, leave the vehicle, identify the reasons that fire when the fire immediately. However, if the vehicle fierce fire must not again try to fight, far from it, to avoid the vehicle fuel tank explosion. If the car is on fire after the collision, if there is awareness but also to move, to hurry out of the bus, next to the person must leave the vehicle as soon as possible to help the injured. If you can not open the door, and quickly smashed the side window glass with sharp objects, once the cracks, you can escape with their feet suddenly flung open.
Prepare a hammer in the car is necessary.
Clothes catch fire, do not run
If your clothes catch fire, should quickly take off clothing, or lay on the ground slowly rolling, pressing off flames. You can also use irrigated fire. Do not stand or run, that will only make the fire more prosperous.

Summer vehicle maintenance knowledge to pay attention to three anti

No sign of summer, "bam" sound to hit the. In summer, some of the trouble plaguing a lot of "car", the road tank "boil", the engine "sticky cylinder", and fire, puncture, short circuit damp very much, normally on the car lighter, drink has become a "dangerous elements." Owners who are wondering, normally good car ye become so fragile it? Introduced in summer and 51 small holiday return vehicle maintenance and use of special note, the owners want to help you!
Regular maintenance of spontaneous anti-
Spontaneous combustion of a variety of reasons, are generally circuit, the circuit and caused damage to car modification parts. The most common cause of the accident the car ignition is short circuit, the probability of its occurrence in more than 60%. Caused by electrical short circuit because, first, the aging, resulting in high temperatures caused by climate cooling slowly; Second, some owners after buying the car, a car equipped with a variety of additional electronic devices, such as electronic anti-theft devices, high-end audio, which are increase the load on the car circuit.
Prevent car ignition, the method is very simple. First, the basic approach is to periodically do maintenance to the car, check engine, oil circuit and to see whether aging and oil spills. Second, to minimize the installation or modification, not to increase the burden of electronic circuits. If the car is modified, in particular, lights, sound, etc., should be all-round check. In addition, normally keep a car with the car also has a number of considerations: the car must be equipped with a fire extinguisher, just in case; this season, not the lighter, perfume, air fresheners and other combustible materials placed in the car for a long time under high temperature exposure, to avoid the expansion of the physical cause spontaneous combustion caused the explosion and then; a long road, the car should be appropriate to break, to avoid overload.
Puncture proof tire pressure down
Hot summer is high season car tire. As the temperature is high, but the quality of the tire off, or if their tire pressure is too high, after the expansion of gases inside the tire will cause a puncture. Therefore, the proposed tire owners will be reduced by 10%, adjusted to 2.2 kPa. In addition, owners can also inject nitrogen tires, because nitrogen is an inert gas, can reduce the risk of puncture. Of course, the owners should pay more attention this season on tire maintenance, if there are injuries, should be promptly repair or replace.
Ensure that anti-heat "boil"
"Boil" is the car's radiator temperature reaches the boiling point. Once the car "boil", the owner should be cooled quickly to find parking in the shade, let the engine idle, and opened the hood to improve heat dissipation, when the temperature drop down, add enough water to give the tank. Usually, the owner should always check the cooling system, and look at whether the water tank. Long distance driving or driving, one should always pay attention to water table reading the instructions.

Summer temperatures protect the car car hair prevent "burn"

School Quotations: car enthusiasts, known as the "car enthusiast." However, interest can be fever, cars are definitely not "burn."
Sunshine, to make you and your car safe through this hot summer, the rookie class has been a continuous multi-stage and share a summer car trip, and vehicle maintenance experience and knowledge need to pay attention. In this issue, we focus to look at the topic of auto ignition.
Guangzhou traffic police official under the facts speak microblogging published traffic sources, into May, Guangzhou has been a spate of car ignition of the accident. May 6, Huanshi cars spontaneous event occurred; 10, Zeng Cha Road, Fuli Peninsula radiation direction of the city of access, there is a car ignition; 19 pm, South China Expressway three there was a large truck aging mechanical accident caused by spontaneous combustion; 20, A-line within the loop Hengfu export, have a car ignition; 27, the inner ring road B line train station with a taxi on the spontaneous combustion ... ...
Why car ignition?
Circuit, mostly spontaneous incidents the main cause of fire
According to traffic police survey, in which spontaneous combustion accidents, auto electrical fire accounted for a large proportion of spontaneous events. Which the aging and auto electrical circuit overloading are the reasons. In addition, electrical installation, modification caused by short circuit is causing a few car ignition key reasons.
After starting the vehicle, the engine ignition coil when the temperature is high, especially after years of use, easy to make high-voltage ignition wire insulation softening, aging, dehiscence, ignition high-voltage breakdown of insulation and easy to produce high-voltage leakage, short circuit leading to spontaneous combustion. In addition, many owners prefer to install their own or modify a variety of electrical equipment, such as headlights, stereo, embedded car navigation, etc., often require alteration of the original car circuit. Should an unauthorized modification of shops, it is easy to leave security risks, can lead to short-circuit.
In addition, the current very high level of automotive electronics, with more and more electronic equipment, automotive applications also makes intelligent automotive electronics corresponding substantial increase in power consumption, a variety of wire and the circuit is more intensive. Automotive electrical systems on the load space is limited, a large number of vehicles increase the variety of additional electronic devices, may also increase the burden on car circuit, causing spontaneous combustion fire.
Oil spills can also cause spontaneous combustion temperature
Many car owners usually do routine maintenance or testing will be found when the vehicle chassis on the individual components, such as engine oil, transmission, and even the brake pipe will appear more or less of oil spills, the increasing temperature in the summer, these are likely to become self-ignition of the fire point, and usually a lot of accidents have occurred due to spontaneous combustion oil into the sky.
Now there are many flammable liquid vehicle (liquid fueled) exists. These flammable liquids including gasoline, diesel, automatic transmission for oil, power steering oil, engine oil, transmission oil, gear oil, brake oil. All flammable liquids (liquid fueled) itself has an ignition temperature, it will ignite once it has reached this temperature, without any spark or flame to inspire. Under normal circumstances, these various types of oils and lubricants, are not prone to spontaneous combustion, but a lot longer due to the use of vehicles, asphalt sealing component aging, or poor quality parts, oil leaks will occur. At high temperatures, sparks, or encounter other combustibles, combustion occurs.
How to prevent car ignition?
1 is recommended before you travel, especially long-distance travel, you must look at the car, whether the engine oil, chassis oil spills, pipeline rupture and other signs of aging, perhaps to a professional repair shop or the 4S shop, it was discovered problem resolved immediately.
(2) age of the vehicle more than three years of the car, especially on their own modifications to the lights, sound modified vehicles, but also in the summer before the full circuit check on the changes over the line, but also to pay special attention.
3 car suspended for more than five minutes, turn off the engine should be timely because of the higher surface temperature in summer, when you are idling at the roadside and others, the waiting time under the exhaust pipe is higher than the maximum temperature point 800 ℃. If you have hay on the ground parking, paint, cigarettes or other flammable items, in the long baking will be on fire, so the car lit.
4. Do not put flammable substances on board. There are a lot of smoking habits of drivers, like the lighter on the center console, cigarette lighter for a long time after exposure has been very prone to explosion. Another perfume contains more alcohol, and very easy to fire. In addition, as carbonated drinks, excessive heat may explode.
How to do in case of spontaneous combustion?
1 in the road, once the smell of coke smell or see smoke, immediately turn off the safe place to park and turn off the power, tighten the hand brake, leave the vehicle to identify the reasons. Found that when the fire alarm immediately.
2 If the engine compartment fire, the front grille should start spraying extinguishing agent at the inward, do not rush to open the hatch, to avoid fire by wind, the more fuel will be greater. If you have not see the flame front, in the case of sufficient fire extinguishers can only be opened lid to extinguish the fire.
3, with some fire extinguishers to spray fire extinguishing agent, if found later, the fire is so big, then as soon as possible away from the scene, first to protect personal safety.

Routine car maintenance knowledge, "a four-frame" everything has to be replaced

Oil grid, grid gasoline, air cells and cells known as automotive air-conditioning, "a four-frame" Although their size is not large, but in the process of car use is indispensable. Oil cells, like human lung cell gas, which filters out the oil, gasoline, among the impurities, making the engine to operate normally; air box and air filter box is also a lack of their filter, no matter how good the cars could not walk far, even the best air conditioning smell. Yellow Prey senior technician Linweihua remind owners should pay attention to the car each "cell", replace them, the most expensive is not necessarily the best.
Oil grid
Oil grid role: As the name suggests, cell function is filter the oil inside the engine oil to improve their cleanliness and lubrication, thus reducing engine wear, so as to play the best features.
Working mechanism: if the heart's blood circulation system, oil pump in the oil is constantly circulating, in the process, we often have a lot of unexpected impurities, and such unclean grid would need to filter the oil.
Recommended replacement time: 5000-10000 km driving each car replaced. Experts suggest that every oil change, should replace the oil grid. The reason is the old oil grid in the dirt, the new oil will reduce the viscosity and cleanliness, impact on the oil circulation rate, can also damage the engine.
Fuel cell
Gasoline cell function: filter between the fuel tank of gasoline to the engine combustion chamber.
Working mechanism: there is usually a variety of impurities in gasoline, fuel tank prolonged use may precipitate some of the dirt, the above reasons will affect the quality of gasoline. Fuel cell is the role of filtering the impurities in the fuel tank of gasoline through the fuel cell of the filter reaches the engine combustion chamber, the clean purity can be effectively protected.
Price: frame material for gasoline vehicles vary, most economic models of the petrol price in the 50 to 100 cells per hour, a few special models of the petrol price in the grid 100 to 200 yuan. High-grade fuel cell car price at 100 yuan, the overall margin is not. Some plant parts, or vice-name gasoline grid, easily lead to oil spills, may lead to spontaneous combustion or explosion, the body, has a considerable personal risk, not recommended.
Recommended replacement time: traveling 20,000 km per car is about.
Air cell
Air cell function: cell installed in the engine air intake location, it can effectively filter dust and impurities in the air, so that the purity of the air entering the combustion chamber greatly increased, in order to ensure fuel combustion.
Working mechanism: the air filter frame formed by the paper, seemingly simple structure, the role but should not be underestimated. Air grid failure will lead to incomplete combustion of gasoline, lack of engine power and throttle body pollution, leading to unstable idle, the engine shake abnormalities and other symptoms.
Price: general models in the price of air cells 50 to 100 yuan, a few special models, such as Jaguar, Mercedes, BMW element models of the air grid price of 100 yuan or more. Vice plant parts are factory parts prices are generally the price of 1 / 3 to 1 / 4, up to twenty or thirty dollars.
Recommended replacement time: traveling 20,000 km per car is about.
Air cell
The role of air cells: cells with air similar to air filter box is the role of dust in the air particles and other impurities, for the automotive air conditioning with clean air.
Working mechanism: Apart from a few older models, the current market, new models are mostly air-conditioned cells with activated carbon, air cleaning has been greatly improved. Replacement of air conditioning is not a long time frame will lead to serious air inlet blockage, resulting in less air out of the wind, cooling slowly, there will be a smell.
Price: basically in the tens of dollars. Recommended that owners use air-conditioned cells with activated carbon, activated carbon more expensive than non-air-conditioned cells only higher.
Recommended replacement time: traveling 20,000 km per car is about.
Tips: you Counting
Dress to the 4S shop of course the quality of these accessories can be guaranteed, but the price is pricey, but as oil and gas grid cells such as the quality that can not be sloppy, how good and cheap parts can do it? Experts suggest that in order to ensure the quality of purchased parts, the owner can take the time to purchase a professional auto parts market, regular brand accessories, original parts or may not be imported, but must be regular brand parts, such procurement, both to ensure the quality, price also low. Place to buy some more cars in the back, on their own or regularly replace the professional automotive service shops to focus on replacement, would not benefit a lot.
Precautions for replacement
1, cell replacement fuel cells and oil installation, should pay attention to the interface seal to guard against leakage;
2, for the air box and air box, replaced to ensure the overall tightness;
3, fuel cell love to make use of the facilities provided automobile manufacturers grade gasoline

Brake fluid should never be taken lightly knowledge about

Automotive brake fluid, also known as brake fluid, is used in automotive hydraulic brake fluid pressure transmission systems. Because of its advantages and disadvantages of the direct relationship between the reliability of brakes, the brake fluid of the purchase is related to the safety of riders, not be taken lightly.
Compared to most private car owners, the brake fluid (brake fluid) is their concern and understanding of at least one of the elements, and talking about the engine, fuel consumption is talking about, talking about the brand, I believe anyone can say on each car a few, can it comes to brake fluid, there are very few people really understand the.
The higher the better brake fluid level?
Reporters from the National Institute of Standards Industry Association web site search on "national standard brake fluid" situation is: January 2004, China's implementation of common standards with international standards of national mandatory product standards GB12981-2003 "Motor Vehicle Brake Fluid" . In accordance with GB12981-2003 "Motor Vehicle Brake Fluid", the brake fluid into HZY3, HZY4, HZY5. Correspond to the international DOT3, DOT4, DOT5. Have high or low brake fluid level, brake fluid in the choice of consumers whether it is the highest level possible? The Great Wall Lubricating Oil Company from China Petrochemical experts told reporters that the higher the brake fluid level, the better the security. In general, micro, medium and low selected line HZY3 car suitable standard brake fluid, and high-end cars recommend choosing HZY4 standard brake fluid. Of course, micro, medium and low car selection HZY4 do not have any problems, and better.
Brake fluid and life are closely related?
According to the brake fluid, one of the drafters of national standard Yanzi Li researcher, the quality of brake fluid is directly related to the merits of the safety of vehicles. In 2005, China has nearly 10 million people killed in various accidents, including vehicle brake not working, brake failure is an important factor. Because of this, the world has always attached great importance to the regulation of brake fluid, the Western countries is to be included in the control areas of road safety regulations. In China, the brake fluid is the implementation of national industrial products production license management. From the Great Wall Lubricating Oil Company's technical experts told reporters that Western countries are demanding standards of the DOT, not the simple deployment can be achieved. Many low-priced domestic market poor quality brake fluid are marked in line with DOT3 standards, product quality and in fact failed.
Two years must change brake fluid?
The answer is also yes.
From the Beijing auto repair company Weijun Jiang Chief Engineer introduction, brake fluid with water features, a long time without replacement will corrode the brake system, to the traffic and security. He suggested that the owner, brake fluid is generally two years or 40,000 km must be mandatory replacement time.
Wei workers said, the real standard of qualified brake fluid has several features: the high temperature, cold, high-speed, heat and other flexible working conditions to ensure power delivery system; of the brake system of metal and non-metallic materials not corrosive; can effectively lubricate moving parts of the brake system, brake wheel cylinders and cups to extend the service life. "If the owner does not choose their own brake fluid, I suggest they do to replace the regular 4S shop, where a relatively secure.".

Car lights also learned

Many people buy a new car, no instructions carefully studied, caused a lot of jokes, the most typical night will not open or close the car high beam light. Readers had to call the newspaper, always complain that their dim lights, light bulbs is not a problem, the last to know, is that he did not turn on the headlights.
Engine light

Automotive knowledge - Hyundai windshield overview

Although the automotive industry and the glass industry are two different fields of industry, the former is a mechanical manufacturing industry, which is light, but the car's development process, relationship between the two grow closer. Glass technology has completely infiltrated the automotive industry to become part of automotive technology, an indispensable one. Now, people are always from the perspective of vehicle safety and appearance to the research and development of automotive glass, has introduced new varieties. Auto glass windshield before the main. As early as 80 years ago, glass has been installed in the Ford plant produced T-car, was installed in the car with the plate glass front, so that drivers remove the bitter wind and rain. From the next few decades, gradually involved in the automotive glass industry, creating a variety of safety glass - laminated glass, toughened glass and other varieties and regions, which greatly improved the performance of automotive glass.
Laminated glass is used in which a transparent adhesive plastic film can be attached to the story or three glass between the plastic strength and toughness and rigidity of glass together, increasing the ability to crush glass. Tempered glass is ordinary glass quenching the internal organization of a certain stress, so that the strength of the glass be strengthened, broken by the impact, the glass will be split into small pieces with a blunt edge, the crew is not easy to damage.
The glass is tempered glass area, a new species, it is specially treated, can break when under attack, the glass cracks can still maintain a certain clarity to ensure that the driver's field of view is not affected. Currently car windscreen area with laminated glass and laminated glass-based, can withstand strong impact.
Appearance of modern car development and is closely related to the development of glass technology. As early as 40 years ago, car windscreen has adopted a one-piece curved windshield, and gradually abandoned the planar windshield. Today's car windshield is generally made of a type of large overall surface type, up and down have some curvature. This curved glass processing, whether from the cooperation point of view or from the assembly, is a very high technical requirements for products, as it relates to models, strength, heat insulation, assembly and many other issues.
The use of curved glass car windshield, the first from the aerodynamic point of view. Because the normal speed of most modern cars more than 100 km, air flow through the curved glass face can reduce the eddy and turbulence, thus reducing air resistance.
With the edge of the window frame and the body surface smooth transition, glass and body totally into one, both visually and overall coordination was beautiful, but also can reduce the vehicle's drag coefficient. In addition, the curved glass with high strength, thin glass can be used for lightweight cars have a certain significance.
Modern cars have to be curved windshield surface flatness of the corner is higher, can not appear on the optical distortion from the driver's seat of any point of view objects are not outside the deformation is not dazzling. Usually before the car neat glass strip along the edge of the glass modification or protection, and now cars are used on the glass ceramic glaze, the so-called "black border."
There are also many car windshield coating, a reflective coating process or to improve the composition of the glass, only to visible light to enter inside the sun, blocking the ultraviolet and infrared, to a large extent by reducing the crew of hot pain. This is called "green glass" of the modern car glass, has been widely used.

Basic knowledge of automotive transmission

Transmission with this car several functions: Change the gear ratio, wheel torque and speed to expand the scope of the changes to adapt to constantly changing driving conditions, while the engine in a favorable (higher power and lower fuel consumption) of the conditions of work;
The same direction of rotation of the engine case, a car can travel backward;
The use of neutral, interrupt power transmission to the engine to start, idle, and to facilitate the transmission shift or power output.
Transmission by the transmission speed and control institutions, when necessary, you can also install power output device. In the classification in two ways: by way of gear ratio changes and by the different ways to manipulate the points.
By way of sub-transmission ratio change:
There-stage transmission is the most widely used one. It uses a gear drive, with a number of value transmission ratio. According to different types of gear used, there is a fixed transmission axis (normal transmission) and the axis of the rotary transmission (planetary gear transmission) in two. Currently, cars and light, medium truck transmission gear ratios are usually three to five forward gears and one reverse gear, the heavy goods vehicles using the combined transmission, then there are more stalls. Number referring to the so-called forward transmission file number of stalls.
Non-stage transmission gear ratio of its value in a certain range can be infinite number of level changes, a common power type and hydraulic type (moving liquid) two. Type CVT transmission power transmission components for the DC series motor, in addition to the trolley bus applications, but in the ultra-heavy duty truck transmission systems are also widely used in the trend. Moving hydraulic CVT transmission components for the torque converter.
Integrated transmission system refers to the torque converter and transmission gear are level consisting of hydraulic mechanical transmission, the transmission ratio can be between the maximum and minimum values ​​refer to within a few intermittent for stepless changes, the current used more often.
Way by manipulating points:
Force-operated transmission gear shift is directly manipulated by the driver shift.
Automatically-operated transmission shift its gear ratio is automatically selected and the so-called "automatic" refers to the mechanical transmission with each stall transformation is reflected in the engine load and speed of the signal system to control the actuator and the shift system achieved. The driver simply manipulating the accelerator pedal to control speed.
Semi-operated transmission, there are two types: one is commonly used in automatic control of several stalls, stall rest manipulated by the driver; the other is pre-style, with buttons that the driver selected gear in advance, in step the clutch pedal or release the accelerator pedal, turn on a magnetic device or hydraulic device to be shifting.

Car repair and maintenance of the "four don'ts."

1 do not like nuts and bolts tire repair wheel coated in oil, a few private owners in order to prevent the wheel nuts on the bolts to rust, when the ingenuity to install bolts and nuts are coated with oil, not knowing that this practice is not only wrong, but also to the traffic safety bring some risks. Tighten bolts and nuts after each other with self-locking features. And coated with lubricant, the coefficient between the two becomes self-locking self-locking performance of filial piety. In the car at high speed, very easy to loose bolts and nuts and even fall off, causing traffic accidents.
2 Do not wash with water body within the summer, the common side of private car owners who wash the body with water, wipe with a cloth while in the private car owners is to be reminded: The interior is best not to rinse with water directly. Because the pad underneath the cab floor is not "Plains", the structure needs to make the groove below the cab floor pads, vias, very much. After washing with water, or deposited in the groove is not easy to dry, either from the flow through the hole on the gearbox and other components from corrosion. Especially the sealing performance of the car is more wash water can not directly inside the body. The correct way is to wipe with a damp cloth, but to avoid stagnant water.
3 different brands of coolant do not mix Everyone knows that lack of engine coolant should be added in time, but you are of different brands of coolant temperature with the use of it? If so, advise you to let go as early as possible to liquid cooling, re-add the same brand of coolant. Because different brands of coolant may be significant differences between the chemical properties, such as an effective preservative for black metal, but often have a corrosive effect on aluminum products; applied to aluminum alloy preservatives are harmful to the alloy. Since different brands of coolant used in different preservatives, so you can not mix.
4 EFI car will not start first step on the throttle kicks to start the engine throttle, the habit of many drivers, especially in the winter cold start. However, this method does not start for EFI cars. Equipped with electronically controlled fuel injection device of the engine carburetor engine different from ordinary, it's fuel injection control device according to engine temperature, oil condition automatically adjust the volume, start the engine smoothly, that is, in cold start, fuel injection control device can automatically increase the fuel supply. Therefore, the EFI car engine is started, no need to step on the gas, not to step in before the start of continuous emergency, or start the engine but bad.

Car heat proof film works

Car explosion-proof insulation film theory
Insulation film is nickel, silver and other metal elements coated by sputtering on the grassroots level in the security, the metal layer selectively to the sun in a variety of geothermal energy, including infrared, ultraviolet and visible light, heat radiates back. So as to effectively heat and protection of human prayer and automotive interiors from UV damage effect.
Car explosion proof membrane theory
Primary material for the brightly lit safe polyester film (PET film), transparent and has a very strong resistance to impact the ability to effectively protect cab long the safety of passengers, subject to external shocks in the case of safety can play an effective grass-roots cushion the impact of reducing the role of external injury.

Wax / seal the glaze / coating how to choose

Car paint like human skin, and acid rain, oxides, UV like bacteria, mites, as will the car's "skin" for erosion. Now, although the importance of car paint care are valued, but even the maintenance man, not necessarily the relevant knowledge is very clear. Varnish do you really know?
Car paint is normally provided by electrolytic paint, primer, paint three parts, from the chemical composition point of view, the development of automobile paint through three stages: in the 1920s of the alkyd, acrylic paint 1960 80 years of varnish and a mirror. However, you really understand the varnish it?
Varnish layer has two effects: firstly, to increase the brightness and glare paint, the second is to protect the paint layer. It features the following four points:
1 varnish beautiful, high gloss, but prone to scratches. If some hair after washing with a little hard to clean the car of a towel or chamois, you will find hair scratches.
2 present the original material used mainly for high-temperature varnish curing one-component paint: polyurethane or polyester, refinish clearcoat materials used primarily for natural curing two-component acrylic.
3. Varnishes generally contain reduced ultraviolet radiation protection, as long as the varnish layer intact, it can effectively delay aging paint.
4. Varnishes Pu Tongqi more vulnerable than the erosion of environmental pollution. Sources of harmful substances include: carbon dioxide released in car exhaust and carbon black in the aircraft jet fuel falling debris with acid rain, acid fog, acid snow and so on. Once the debris fell on the car, plus the moisture in the air, it becomes acidic corrosion varnish solution. Just a little heat, they start a chemical reaction, corrosion protection of automotive paint layer. Once, twice is not obvious, but if do not do long-term care, this chemical reaction will eventually erode to the color layer, primer layer and metal.
Wax, sealing the glaze and coating products which is the difference?
For car paint, varnish layer, especially the protection of the market there have been a variety of different products, in general, paint protection product is a graphical representation of the following two principles to the effect:
Products in the paint film components of the surface after the film, wax or glazing paint molecules penetrate into the gap, while in ordinary film coating product components will be formed on the protective film layer of solid . Well, the same as paint protection products, car wax, glaze and seal coating products which is the difference?
Wax: Wax is a traditional automotive paint protection products, with natural or synthetic wax as the main ingredient, according to the chemical composition and from different sources can be divided into animal waxes, vegetable wax, mineral wax and synthetic wax. Wax penetration into the paint through the manipulation of gap formation and increase the surface brightness. Light in order to achieve better results, you need a thick wax layer, but this tends to affect the paint color. And poor durability of wax, pouring rain several times lost the original light effects.
Seal the glaze: sealing wax derived from the glaze is a new concept, is a petroleum by-products derived from petroleum products. Seal the glaze to a soft wool or sponge by vibration polishing machine, high-speed vibration and friction, the enamel surface of the molecular strong penetration into the paint cracks in the car, which play a beautiful and paint protection. However, this approach itself will not hurt the paint is still a need to consider. Sealing wax molecules and molecular enamel surface hardness compared to high, and good paint adhesion characteristics, so durability is better than wax. Smaller but the glaze molecules can not fully fill the gap paint, shown by the brightness is lower.
Coating: The product mainly of glass fiber, with a special modification of the silicon / fluorine polymers such as one or several substances formed by coating the surface of the paint, the paint completely isolated from the outside world. Coating thickness is typically 10 microns or less, a polymer coating material is stable, but the polymer will be aging in the air, the effect of also need a long test of time. As the film is thick, may change the color of the paint layer, while a considerable part of the inorganic film, the surface will astringent, not smooth. Good quality coating products, such as turtle license crystal shield coating, which contains a special patented formula of low molecular weight THV fluoropolymers, can significantly improve the paint's gloss, durable finish to improve the anti-aging properties.
Paint for different conditions, experts recommend according to actual needs, choose a different paint protection products above, in order to make long-term as new paint, remove the paint aging troubles. Meanwhile, in order to ensure the quality of construction, better play the efficacy of the product itself, suggested to the owners of friends through the manufacturers choose formal training beauty shop paint care.

Basic knowledge of car run-in period and notes

Car run-in period, but also known as "walking together" period refers to the beginning of a new car or overhaul operation stage, typically 1000-1500 km, which is to ensure sufficient mechanical contact, friction, fit, shape the basic mileage. Car run-in period as the athletes in the competition before the warm-up exercise, the purpose is to enable all parts of the body the ability to function can be adjusted to adapt to the environment improved. The merits of running vehicles, will auto life, safety and economy have a major impact. Car run-in period is characterized by:
1) parts wear faster. Although automobile factory was run according to regulations dealing with, but parts are still rough surface, combined with new parts between the metal particles have more off, so wear and tear.
2) failure-prone. As the parts in the processing, assembly deviations, and also contains a number of difficult to find the hidden dangers in walking together is likely to occur during the stuck parts, heat and leakage and other faults.
3) oil perishable. As the parts go together with the smaller gap during the period, film quality is poor, large temperature rise, oil easily oxidized. More metal particles mixed with oil, so oil quality.
4) fuel consumption. Take in period in order to ensure a small load operation, carburetor installed speed film, resulting in partial thick mixture. Meanwhile, large parts of the friction between the fuel consumption also increased.
5) easy to loose fasteners. To address the above situation, and go together in the period should be noted: limit load, speed, high quality lubricating oil, start the "cold roll slowly forward, low temperature," Slow start, slow refueling, timely shift, brake slowly, strictly control water temperature, always check the transmission, drive axle and wheel temperature. Car run-in period, if any exception should be properly handled, they could not make claims. Car driving to a certain mileage, they should repair and routine maintenance. Running-in oil should be replaced expiration, removal of speed film, full adjustment, fastening of the vehicle to normal technical condition.
Improve the running quality should note the following issues:
1) start the first warm-up, brake separation together. Avoid emergency braking, or not only will run in the brake system has been hit hard and will increase the impact of load on the engine chassis. "From the rear brake first" approach is very time in the running, and in the very situation (emergency brake), the measures taken to protect the engine. Cut can not be used as a good long-term use. When the vehicle had a run-in period, from the clutch and maintenance perspective, it should be "after the first brake off."
2) constant speed running gear of vehicles in motion should be gradual, starting with the most low and gradually add high-end place, must not use the high-bit low speed or low-bit high speed. And frequently changes the gear, do not use a gear driving a long time. Road should pay attention to the engine, transmission, drive axle of the working conditions and temperature changes, control vehicle speed.
3) As for gasoline, high octane gasoline plant run-in period should be preferred to prevent deflagration, the ignition in case of difficulties, should be delayed ignition time, and time shift and avoid hard acceleration. Run-in period is over, inspection and maintenance before entering the period of normal use, maintenance as follows: Check and adjust the fan and water pump drive belt tension; check and adjust the camshaft timing belt tension; adjust the valve clearance; check the engine cylinder head screws tight degree; replace the engine oil filter; replace the engine oil; added radiator coolant; adjust ignition timing; remove air filter dust; adjust the idle speed and idle speed mixer pedal clearance; check the brake fluid volume to see if there no leakage; adjust the brake pedal travel; check hand brake lever and cable travel; check and tighten the wheel nuts and wheel connection; check the transmission and differential oil; check other key female tightening torque; Check Steering System gap tightness and oil leaks, steering wheel free travel is appropriate. Therefore, the car running period must ground observation, ground inspection, found fault and remove, to do regular maintenance work, making the car always in good technical condition operation.

Woven velvet seats clean and Conservation Act of knowledge necessary maintenance car beauty

Fabric fabric seats, disposal is relatively simple. Woven velvet seats are not dirty, used a long-haired brush and strong suction vacuum cleaner with one side brush seating surface, while the suction with a vacuum cleaner to suck dirt out. For particularly dirty seats, cleaning will be carried out the following steps: First, wash with a hair brush the dirty part, and then with a clean cloth dipped in a small amount of neutral detergent solution, in the case of a comprehensive semi-dry wipe the seat surface, and finally clean the seat with vacuum cleaner again, and elimination of excess water.
With a vacuum cleaner to remove dust, dirt debris. If the dust on the cloth or condensation is difficult to remove with a vacuum cleaner, first look with a soft brush and then vacuumed.
With a dry cloth to wipe the surface of the fiber, and then thoroughly dried fiber seat, if the cloth is still dirty, use a mild soap and warm water to clean and thoroughly dried.
If the dirt does not come out clean, try the market to sell fiber cleaning agent. In the more obvious first place to use this cleaner to make sure it does not have a negative effect on the flannel. According to the instructions to use this cleaner.
Usually best not to eat in the car, not eating is not sure to pay attention, do not let the food fall on the seat fine slag, in order to avoid the breeding of mites or other organisms which produce odor.

Car paint protection and paint everyday knowledge

Automotive paint baking paint generally. Inside the depot, frame, body welding done manually repair the body, the next process is painting. In general, the first primer. Immersed in the syrup-like white body paint tank, remove the dried paint; then into the clean room, with electrostatic paint spray painting process, and then drying temperature of about 200 degrees. Some would go on a layer of varnish.
This paint process and you're done. There are several general finish: Putong Qi, metallic paint, pearl paint. Pu Tongqi main components of resins, pigments and additives; more metallic aluminum, so the future looks bright completed; pearl paint is to add cloud masterbatch. Mica is a very gorgeous effect. If it is metallic paint with varnish layer, the paint looked like bright.
Focus on routine maintenance
1 vehicles before, during and after, to promptly remove the dust on the body, minimize the dust absorption of body static electricity;
2 rain and washed. After the rain the rain stains the car body will gradually increase, if the rain does not wash with water stains as soon as the passage of time will damage the finish.
3 washing should be carried out after cooling the engine, not in the hot sun or high temperature washing vehicles, so as to avoid leaving traces of detergent to be dried. Usual-it-yourself car wash to use special detergent and neutral running water, should not use alkaline detergent, soap and detergent behind to prevent the wash south of the grease paint, paint accelerated aging.
4 scrub vehicles to use clean, soft cloth or sponge to prevent the mixing of metal and sand quiet, do not use a dry cloth, dry towel, dry sponge clean the car, so as not to leave streaks. Wipe should be along the direction of flow from top to bottom and gently wipe, horizontal wipe, and should not circle.
5 for special corrosive marks (such as asphalt, bird droppings, insects, etc.), must be promptly removed. In this regard, we must use special detergent, not free to use the blade scraping or eliminate gasoline, so as not to damage the finish.
Paint repair
Generally small abrasions, such as paint surface wounds, scars, white, or even scratch the paint surface is made into filaments, but in fact are not necessary to make paint. Light, with the wax you can handle; heavy, to be polished up on it.
More serious, and can see the color of the lower primer (for example, white paint below the bottom). In general, insurance carry, mirrors and wheel eyebrow these parts are plastic, will not rust, minor problems, patch up paint is pretty does not matter. If it is blown to the body of the plate above it to make paint, otherwise, even a small damage, steel will rust, that time, even up painting effect is not ideal.
Up painting Notes
First, all places, even in the original, up paint will not use any "original paint!" If the repair shop tells you they are using the "factory paint", it must be lying to you, the purpose is to improve maintenance. The reason is simple: original paint after a good spray painting process with the baking temperature to 200 degrees. The finished car so many parts, how many 200-degree temperature capability it?
However, under normal circumstances, the manufacturers will still recommended to specify a special brand of service station repair paint.
Second, the repair paint colors are out of repair before the deployment. The reason is simple: Your car may be opened for a few years, the paint has begun to fade, although you can not tell. If you are parked outside, a different degree of fading on the direction will be slightly different. To match the colors as the original, only now transfer large color computer repair shop, with the paint and the original paint color is the eyes of ordinary people do not tell, this point can rest assured.
Also, color does not appear to as much as possible, even if you just need a little touch-up painting, maintenance shops, will be to block all repainted. For example, there is a place on the door need to fill, then, to prevent rubbing of the world, half of all fans or fan spray half. Thus, if there is a small little color they will not see it. This is not difficult to understand why the insurance scratch the front left, and painted the whole bumper to be the truth, and to the maintenance of plant can not say when the cheating.

Car maintenance knowledge dedicated to Fans

    Although the day is also still very cold, but spring is getting closer and closer to us, and for the low-temperature environment in the winter driving a car, it is time to look at the good maintenance. Another early spring temperatures start to pick up, we will also have special maintenance strategy.
Spring season, we took off the thick of winter, and our car driving through a cold winter, also need to trim. Bacteria need to be cleared, lubricants need to be replaced, air conditioning systems need to be cleaned. Spring maintenance of vehicles in the following aspects in particular need to attract the owners attention.
Clean before use of air conditioning
After several months of travel, automotive radiator, condenser surface will cover a lot of dust and other debris catkins, which will produce the vehicle and air-conditioning cooling effect of high temperature and poor, resulting in a long time fan of electronic air-conditioning work, easy to damage air conditioning, but also to increase vehicle fuel consumption, while the vehicle owners will find the noise increases. Therefore, in order to avoid this from happening, the spring should be clean water tank with high pressure air gun condenser surface.
Spring wind, easy to play dust, but when air-conditioning duct and evaporator surface dirt and impurities excessive, prolonged use of mildew occurs in the case of warmer weather encourages the growth of bacteria. At this point the owner will find air conditioning odor appeared to affect the health of occupants. Therefore, before using the air-conditioning, in addition to cleaning the tank condenser surface, but also clean the sterilization of air-conditioning system, replacement air filter. After this treatment, the owner can safely use the air conditioning had.
Replacement of the viscosity grade of oil for the season
Lubricant in use for some time, due to air oxidation, pollution and other factors will decrease the quality of its own, and thus lose protection for engine lubrication, so time quarterly oil change becomes necessary.
Selection is mainly based on oil viscosity level of the ambient temperature. Under normal circumstances, 4 April-September in most parts of the country the owners choose to 20w-40 or 10w-40, No. No. summer oil.
Also in the selection of lubricating oil viscosity grade must also be considered the engine load, speed and wear. If the engine load, low speed or severe wear, high viscosity oil should be used, and vice versa on the selection of a smaller oil viscosity.
Check the oil amount, to pay attention to the engine after each run for a period of time, how much oil will be consumed, according to the actual situation to add oil first marking. Remember to add no more than mark on the oil line, oil or because of excessive rotation of the crankshaft to increase resistance, reduce engine power output. Moreover, too much oil, there will be burning engine oil, take the blue smoke of the phenomenon, leading to increased fuel consumption, speed up the cylinder and piston wear and shorten engine life.
Adjust tire pressure
Timely to re-adjust the tire pressure data, temperature is increased by 10 ℃, tire pressure will increase about 7-14kpa. Therefore, the weather gets warmer, with particular attention to tire pressure with the ambient temperature due to a change. As a result of tire problems and accidents on the highway has reached 70%, high-speed road tire issue has become the number one killer.
Keep the car clean and dry to prevent growth of bacteria
The car itself comes from two sources, one from the auto parts and interior decoration materials in the release of harmful substances, such as benzene, toluene, formaldehyde class; the other is inside the accumulation of pollutants such as dust and microorganisms, especially in spring temperatures gradually increased, proliferation of bacteria growth is to provide for a variety of conditions. Bacteria priority is to let the car to keep dry indoor health, especially for car seats, floor mats, and other health corner outlet to do a thorough cleaning, to keep the car clean and dry environment.
Insiders suggest the purchase of a car with a vacuum cleaner for the timely removal of dust and microorganisms inside the car, a good idea. But the selection of car vacuum cleaner, you should pay attention to power small vacuum cleaner should not be selected. Now the market there is a vacuum cleaner using inverter technology, it can be car 12V DC power into 220V AC power supply used car vacuum cleaner, power up to 180W, the general vacuum cleaner suction 8 to 10 times.

Small talk about car maintenance knowledge

 1 change of tires.
Here's another tire is not new to everyone, but to re-adjust the position of four tires. What good is it? This can reduce the bumpy road to bring the uneven tire wear, usually tire wear was more serious side. It is recommended you change the tire normally in about two years or replaced about 6000 miles each exercise. Changing a tire for tires used on the corner, right front tire and left rear tire swap. However, this approach must change the tire as the car's powertrain and tire type. Usually we will car maintenance manuals supplied with a detailed record of the process of changing tires. We should always remember that the best fitted rear tires, so you can maximize the safety factor; there is not the direction to a tire change, which is most important.
(2) the tire air play enough.
Make our tires deflated tire by 15% of life and exercise the same fuel mileage slightly Cadogan, probably about 10% (also with a lot of is not it?). Enough gas to fight the tire maintenance which is probably the easiest part of. Buy a tire pressure gauge, about 20 dollars or so, each time filling the measure about their tire pressure. Fully charged air tires make the car faster and more effort to open up!
3 starting speed.
Initial speed must be slow, because when gasoline and cool and thick, easy to damage delicate engine. Another way is to install a cold start for the car heater, the use of the electronic heating device can make your car start with a warm engine, would like as fast!
4. I remember pulling the handbrake.
Even if the car is infinitely variable must remember pulling the handbrake, especially when parked on slopes. Handbrake brake and make our cars more firmly attached, and can extend its life.

And other engine cooling, check the coolant liquid level should be at least between the bit and low, or distilled or purified water should be added (can not add mineral water), or frozen liquid, adding water to the liquid height can not exceed the full bit. Found to decrease rapidly within a short time the coolant should be checked for leaks or cooling system to the service station to check.
