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.
