Why Do Cars Need Fuel?
1 Answers
Because cars need fuel to start. Reasons: Because cars use internal combustion engines as their power source, and internal combustion engines include gasoline and diesel engines. A gasoline engine is an engine that uses gasoline as fuel to convert internal energy into kinetic energy. Due to gasoline's low viscosity and rapid evaporation, a fuel injection system can be used to inject gasoline into the cylinder. After compression reaches a certain temperature and pressure, a spark plug ignites it, causing the gas to expand and perform work. Characteristics of gasoline engines: High speed, simple structure, lightweight, low cost, smooth operation, and easy maintenance. Gasoline engines are widely used in cars, especially in small vehicles.
