[0002] Engines and motors are two different energy conversion devices. Engines mainly generate energy by burning fuel (such as gasoline and diesel), which then converts thermal energy into mechanical energy. In an internal combustion engine, fuel is mixed with air and ignited to produce high-temperature and high-pressure combustion gas, which pushes the piston to move, thereby driving the turbine or crankshaft to rotate.

[0003] The motor generates a magnetic field by passing electricity, and generates a rotational torque in the magnetic field. When current passes through the wire, a magnetic field is generated, and the rotating magnetic field generates an induced current in the coil, which in turn generates a torque to rotate the motor rotor, which can be used as a motor. The rotation of the motor rotor can also generate current in the stator winding, which can be used as a generator.
