Abstract
A motor/generator is mounted on the turbine shaft of a supercharger in an internal combustion engine. Whether the motor/generator should operate as a motor or a generator is determined by a signal from a flow rate sensor that detect the rate of fuel flow and a signal from a rotation sensor that detects rotation of the internal combustion engine. When the motor/generator operates as a generator, the fuel flow rate is controlled in response to an output signal indicative of electric power from the generator. When the motor/generator operates as a motor, electric power supplied thereto is controlled in response to an accumulated value of supplied electric power.
