PURPOSE:To assist a turbine and make suction supercharging performable as well as to improve both engine output and torque values, by driving a motor- generator as a generator in time of car driving at a low speed range of an internal-combustion engine because the motor-generator being driven by an exhaust turbine has been installed. CONSTITUTION:When the number of revolutions of an internal-combustion engine goes up little by little and thereby exhaust gas energy grows large, a turbine impeller 9 and a shaft 7 are driven beyond the revolution speed of a motor- generator MG being electrically motor-operated, whereby this motor-generator MG is set in motion as a mere generator, making a starter coil 16 induce voltage, and this induced voltage is put back to the power source side. In time of starting the internal-combustion engine and at a low speed range, power is fed to the motor-generator MG which is, in turn, made to serve as a motor. |
