What is the working cycle of a gasoline engine?

[NatalieLynn]

For each power stroke, the engine goes through four strokes: intake, compression, power, and exhaust. Completing this sequence is called one working cycle of the engine, and repeatedly completing this sequence constitutes the engine's working cycle. Below is an introduction to engine-related content: 1. Energy conversion: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. 2. Device: The term engine applies both to power-generating devices and to entire machines that include power units (e.g., gasoline engines, aircraft engines). The engine was first developed in England, so the concept of the engine also originates from English, with its original meaning referring to "a mechanical device that generates power."
