[0002] The automobile engine is the machine that provides power for the car. It is the heart of the car and affects the car's power, economy and environmental protection. According to the different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric car motors and hybrid power. Common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of the fuel into the mechanical energy of the piston movement and output power to the outside. Gasoline engines have high speed, small mass, low noise, easy starting and low manufacturing cost; diesel engines have a large compression ratio, high thermal efficiency, and better economic performance and emission performance than gasoline engines.
