How gasoline engines work？
Gasoline Engine is an engine that uses gasoline as a fuel to convert internal energy into kinetic energy. Due to the small viscosity of the gasoline and the rapid evaporation, the gasoline injection system can be used to inject the gasoline into the cylinder. After being compressed to a certain temperature and pressure, the spark plug is used to ignite the gas to expand the work. The gasoline engine is characterized by high speed, simple structure, light weight, low cost, stable operation and convenient use and maintenance. Gasoline engines are used extensively in cars, especially small cars.
The engine is a machine that converts chemical energy into mechanical energy. Its conversion process is actually the process of the work cycle. Simply by burning the fuel in the cylinder, it generates kinetic energy and drives the reciprocating motion of the piston in the engine cylinder. The connecting rod connected to the piston and the crank connected to the connecting rod drive a reciprocating circular motion around the center of the crankshaft to output power.
