Introduction To Gasoline Engines

A gasoline engine is an engine that uses gasoline as fuel and converts internal energy into kinetic energy. Due to its low viscosity and fast evaporation, gasoline can be injected into the cylinder using a gasoline injection system. After being compressed to a certain temperature and pressure, it is ignited with a spark plug, causing the gas to expand and do work. The characteristics of gasoline engines are high speed, simple structure, light weight, low cost, smooth operation, and convenient use and maintenance. Gasoline engines are widely used in automobiles, especially small cars.
