Abstract
A supercharger of an engine comprises a motor/generator, a compressor provided in an air intake system of the engine, and a planetary gear mechanism. The planetary gear mechanism includes a sun gear connected to a driving shaft of the engine, planetary gears connected to the motor/generator and a ring gear connected to the compressor. The controller drives the motor/generator to control a rotational speed of the planetary gears. Through the control of the rotational speed of the planetary gears, a rotational speed of the compressor is controlled independently of a rotational speed of the engine. Thus, the rotation speed of the compressor can be continuously changed over a range from zero to a higher rotational speed than the engine rotational speed. Any desired supercharged pressure can be generated independently of the engine rotational speed.
