Next we want to talk about is closely related with the engine parts, we call the electronic throttle. You must go to ask is not to use electronic throttle? So what good is it electronic throttle? Here there is no comparison here to understand why electronic throttle? I let the horse with the most simple instructions you can remember, that the mediation of electronic throttle fuel consumption would be more correct, you know that oil and gas and air mixture ratio? 14.7:1, so if you are using the electronic throttle, he will help you mediate it into line with such a transfer, so that when you give the oil, would be more efficient, will not cause loss of smell and waste, so a we must first ask a good car engine is not electronic throttle, low fuel consumption, more importantly, is noise.
CAN-BUS
Then talk about the CAN-BUS, at least in the top 250,000 vehicles equipped with such components can, I explain what is CAN-BUS, I use the most simple words so that you may know, the last open after the engine can see a series of lines, these lines had gone into a fiber, if I cut it into two words, if you do not touch, you can immediately see a light, transmission speed is very fast, it is not the cost of natural words, the very high. You can imagine, this thing is a car in the link, if still a lot of lines, the line is not the packaging, plastics, and a copper wire inside the bag, so the plastic will be used for a long time after the aging, not to mention vehicles in the exercise of the process temperature is so high, so the plastic will break, it will produce a short circuit, so the use of one or two years more than three years when the car is not there something wrong here is, in fact, line problems are now the these lines into a fiber, the first, when we open the hood, when only one optical fiber; Second, there is no aging, will have failed, resulting in short-circuit phenomenon, but the cost is very high, basically we use the LAN the control system. The more high-end cars inside the CAN-BUS, the more there are two, three, four, of course, price is not the same, and now we see more than 250,000 cars have this thing, do not underestimate this thing, in fact, he is a module that there are many switches, components, interfaces, if the two modules to be connected, only that an optical fiber, so the transmission faster, not a problem, so choose the time , first ask you this CAN-BUS vehicles have set, if not, ensure that its technology, the cost is also not up to standard, so can not call it a good car.

About gasoline engine electronic control
Gasoline is a mixture of petrol and air in the cylinder internal combustion heat to mechanical energy and thermal energy conversion power plant. Automotive gasoline four-stroke gasoline engine normally, as shown. We finished gasoline continuous intake, compression, expansion and exhaust work done called four-stroke gasoline engine a working cycle. Continuation of the work cycle constantly, constantly out on the gasoline engine power output.
Air-fuel ratio is a combustible mixture in the quality of air and fuel ratio. Typically, the gasoline engine during the intake stroke is inhaled mixture of fuel and air, because the mixture is formed in the outer cylinder, fuel and air mixing time is longer, so after entering inside the cylinder has been more evenly mixed. Into the combustible mixture of gasoline in the late compression stroke ignited by the spark plug, and acting outside the expansion stroke. Gasoline into the gasoline output power is proportional to the combustible mixture inside the number, the more into the mixture, the greater the power output of gasoline.
By the gasoline engine works we can see, the combustible mixture in the cylinder preparation and reliable, timely decision to ignite the gasoline engine operation and power stability, economy and other critical factors. Completion of these two functions of the gasoline engine fuel supply system and ignition system.

Warm winter car preferred electronic library
More and more people buy a car, but the cold northern weather allows new owners who complain incessantly - but not start out to catch a car, fill the tank cracking of antifreeze but do nothing, than rent a garage to rent also your ... ... has recently appeared on the market Tongfang "electronic warm library" that can solve your immediate problems.
The industry believes that, as the technology matures, "Electronic Library warm" instead of the traditional "warm library" will be the inevitable trend of market development. "E-warm library" is a vehicle electronic products, it uses real-time monitoring engine temperature sensor the temperature of the body, starting when the temperature falls below the preset temperature, it can automatically start the engine; turn off when the engine temperature reaches a preset temperature, the control immediately engine flameout. Installation of the "electronic library warm", can effectively ensure the best start the engine in the state, greatly reducing the temperature starts to mechanical wear, reduce fuel, lubricating oil consumption. The night started the engine fuel only 0.05 - 0.22 liters, according to the current 3.45 yuan / liter per month only takes about $ 30 of fuel costs.
In recent years the rapid development of automobile industry and market competition has greatly promoted the application of automotive electronic technology and development, Qinghua based on detailed user needs careful research, a series of auto electronic products, in addition to "warm electronic library", the There tire pressure monitoring system (TPMS), car inverter, reversing radar, digital tire gauge, explosion-proof film and automotive electronics.
Magical car radio
1, the car radio usually can be used to monitor the frequency of traffic police, has many advantages. Can really understand the market when, for example, what specific action today, the main investigation of the rolling line or overtaking; which sections of the accidents, traffic jams; which leaders come, which way to freeze (this is often the case, the car was on the road solidification is twenty minutes commonplace until Qianhuhouyong fleet of police cars to clear the way through the siren blew up), after which you hear in advance flexibility, eliminating a lot of trouble.
There is an even better effect, when you are feeding and not illegal or pretending to ignore him, this traffic will use the radio to inform the traffic police to intercept the next place you (will), you can hear the slide of the Po . If interest, but also, and his bucket of a bucket: Hold the radio in the frequency of firing key, nickname called "strangled" because the car radio power is much greater than the handset, he lost for words, You are free to escape.
Interesting? Oh, this is a thing of the past, do not follow yo, or I have suspected of abetting.
2, if a group has a car radio, then use the most, and many things can be with each other, who's car broke down, not oil, in a mistake in the pit, etc., usually you can also chat Couqu, pass the lonely .
Than one case can illustrate the problem: several years ago, a taxi company in Changchun dozens of vehicles equipped with a car radio, as they occupy a favorable position to play a decisive role. Changchun Airport is a fat, when we all started to go with the gun, when a dispute, they shouted through the car radio one, there is mobility vehicle, soon to a bunch of brothers, the others fight off, So this fat land occupied since.
3, the first two magical are crooked, regular use is there. I am also ready to implement. Is to use the car radio to security, in-vehicle platform audio output by one dual audio decoder, drive a multi-contact relay, the relay can be cut off or short circuit necessary part of a hand-held radio transmitter with dual audio code to control the distance of up to several kilometers.
Best to frequency modulation in a base table, not only in the urban areas, or even tens of kilometers in the urban periphery are valid. This has a lot of base stations in each city, urban construction bureau, industrial and commercial bureau, customs, postal, telecommunications, public security, government, and many more have to be dozens, how can also be found in these sectors, an acquaintance, (some of this more formal Otherwise, help yourself can be, anyway, once or twice a year may not have access), so that your car stolen within twelve hours, can stop remote control, you can "voice traffic", etc. The radio announcement of the release to find cars. Thieves can not break in a short time you spent a lot of thought made Cheats.
Flight control system to reduce fatigue
Cruise control system or the English name for SpeedControlSystem CrusieControlSystem, which is a fatigue reducing device drivers.
When the car in long-distance highway driving, you can start the cruise control system automatically car fixed at a specific speed, eliminating the long foot pedal drivers suffer. At the same time, it can in the state of the pre-cruise speed for acceleration and deceleration of the regulation.
In the 1960s the United States, the cruise control system has been widely used in the car, the current domestic production of some high-end cars such as the Passat, Accord, are also equipped with cruise control.
In addition, the cruise control system also save fuel and reduce emissions benefits, because the car has a corresponding economic rate, when the driver set the cruise control system adjust the speed in the economy can play a role in fuel-efficient.
Specifically, this cruise control system Cruise, cruise speed, cruise deceleration functions.
● Cruise
The control lever switch to ON, you can at 40 km / h over any speed, press (SET / ACC) button for 1 second to set cruise speed, cruise into the state (no throttle, the vehicle can press set cruise speed).
● cruising speed
In cruise mode, each press (SET / ACC) button for half a second to increase the speed of 1 km. Can also hold down the (SET / ACC) key, the speed will automatically improve slowly, until the appropriate speed and then release the button. In addition, cruise control state can step on the gas to accelerate, release the throttle when, the speed will slowly return to the previously set cruise speed.
● cruise deceleration
In cruise mode, each press (RES / DEC) key for half a second to reduce the speed of 1 km. Also has been holding down (RES / DEC) key, the speed will automatically slow down, speed up for re-release it.
● constant speed lifting
In cruise mode, gently depress the brake, you can lift the fixed speed.
● fixed speed recovery
After the lifting of constant speed, simply hold down (RES / DEC) key for one second, do not step on the gas, the speed can be automatically restored to the constant speed cruise speed before lifting.
