Abstract
A turbocharger for an internal combustion engine is disclosed, including a turbine drivable by the exhaust energy of the internal combustion engine, and an air compressor coupled by a shaft to an impeller of the turbine for charging air into engine cylinders in response to rotation of the shaft. A rotor is mounted on the shaft and stator cores and coils are disposed around the rotor. The rotor and the stator cores and coils jointly constitute a motor-generator which operates as a motor or a generator dependent on operating conditions of the internal combustion engine.
