engine

It is a machine that can convert other forms of energy into mechanical energy, including internal combustion engine (reciprocating piston engine) and external combustion engine (Stirling engine, steam engine, etc.). ), jet engines, motors, etc.

For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine is suitable for both power generation devices and complete machines (such as gasoline engines and aero-engines) including power devices. The engine was first born in Britain, so the concept of engine also originated in English. Its original meaning refers to "a mechanical device that generates power".
