The invention discloses an automobile engine which comprises an engine body, a crankshaft and an air conditioner generator. The air conditioner generator comprises a stator and a rotor and is placed on the front portion of the automobile engine and driven by the crankshaft of the automobile engine, and the axis of the stator of the air conditioner generator is coaxial to the axis of a main shaft neck of the crankshaft of the automobile engine. The automobile engine can supply power to vehicle-mounted air conditioner systems, and the air conditioner generator is arranged at the front end of the crankshaft of the automobile engine. The automobile engine requires no belt for driving and is simple in structure and convenient for the vehicle-mounted air conditioner system to adopt the whole distribution structure.

The invention provides a flywheel energy storage system with an electromagnetic coupler, which comprises a motor, a flywheel rotor, the electromagnetic coupler, a frequency converter and a generator, and is characterized in that the motor is connected with the flywheel rotor to drive the flywheel rotor to rotate, the electromagnetic coupler comprises an outer rotor and an inner rotor, and the outer rotor sleeves the inner rotor and is spaced from the inner rotor; the flywheel rotor is in transmission connection with the inner rotor, the inner rotor generates a rotating magnetic field to drive the outer rotor to rotate, and the frequency converter is connected with the outer rotor to change the current frequency of the outer rotor so as to change the magnetic field rotating speed matched with the current, so that the mechanical rotating speed of the outer rotor is kept constant. The generator generates power, accesses the power grid and inputs electric energy with stable frequency into the power grid, the requirement of power transmission to the power grid is met, power electronic devices are not needed, rotational inertia in the power grid can be improved, necessary voltage and frequency support is provided for the power grid, and the capacity of the power grid for efficiently accepting new energy is improved.
