A turbocharger system for use with an internal combustion engine includes an assisting motor-generator and control for enhancing turbocharged internal combustion engine performance with reduced losses inherent to turbochargers incorporating waste gates. The controlled assisting motor-generator provides enhanced turbocharger boost with reduced turbo lag below a boost pressure limit, and can generate electric current at high exhaust gas flow rates.

[ We claim:] [1.] A turbocharging system for use with an internal combustion engine operated by an accelerator pedal, comprising:a turbocharger including a rotor with an exhaust gas turbine for receiving an exhaust gas flow from the internal combustion engine and a turbine-driven compressor for providing compressed air to the internal combustion engine and a sensor for providing a signal relating to turbocharger rotor speed;an assisting motor-generator for assisting the turbocharger in providing compressed air to the internal combustion engine; anda control for controlling said assisting motor-generator and the turbocharger rotor speed, said control comprising a first switch for energizing said motor-generator as a motor to maintain the turbocharger rotor speed at a minimum continuous level, a second switch for super energizing said motor-generator upon the rapid depression of the accelerator pedal, and means responsive to the turbo-charger speed signal to de-energize the motor-generator above a higher turbocharger motor speed.
