A car engine is a device that powers the car
The car engine is a device that provides power to the car, and is the heart of the car, which determines the power, economy, stability and environmental protection of the car. According to different power sources, automobile engines can be divided into diesel engines, gasoline engines, electric vehicle motors, and hybrid power.
Common gasoline engines and diesel engines are reciprocating piston internal combustion engines, which convert the chemical energy of fuel into mechanical energy for piston movement and output power to the outside. Gasoline engine has high speed, low quality, low noise, easy start, low manufacturing cost; diesel engine has large compression ratio, high thermal efficiency, economic performance and emission performance are better than gasoline engine.
