What is the structure of a gasoline engine?

[RoseAnn]

Gasoline engines vary greatly depending on their application, manufacturer, and production era. However, they all consist of the engine block group, crankshaft and connecting rod mechanism, valve train, intake and exhaust systems, fuel system, cooling system, lubrication system, starting system, and harmful emission control devices. Introduction: A gasoline engine is an internal combustion engine that converts internal energy into kinetic energy using gasoline as fuel. Due to gasoline's low viscosity and rapid evaporation, a fuel injection system can spray gasoline into the cylinders. After compression reaches a certain temperature and pressure, a spark plug ignites the mixture, causing the gas to expand and perform work. Characteristics: Gasoline engines are characterized by high rotational speed, simple structure, light weight, low cost, smooth operation, and ease of maintenance and repair. They are widely used in automobiles, especially in small cars.
