The engine is mainly two kinds of gasoline engine and diesel engine. Modern cars are widely used reciprocating piston internal combustion engine. It is through the combustible gas combustion in the cylinder to produce pressure, to promote the movement of the piston and through the connecting rod to rotate the crankshaft to the external output power. It consists of two major institutions and five systems, which are composed of crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system (gasoline engine), starting system, cooling system and lubrication system. Diesel engine ignition method for the compression ignition, so no ignition system.
