An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, Stirling engines, steam engines, jet engines, electric motors, etc. For example, an internal combustion engine typically converts chemical energy into mechanical energy. The term engine can refer to both the power generation device and the entire machine including the power unit.
