ABSTRACT:
A supercharger associated with an internal combustion engine has a rotatable shaft on which there is mounted an electric rotary machine operable as an electric motor or an electric generator. When the motor vehicle driven by the internal combustion engine is braked so as to be decelerated, the rotary machine is operated as the generator to enable the supercharger turbine to act virtually as a load on the exhaust manifold of the engine, thereby increasing the force of an engine brake. When the motor vehicle is to be further decelerated, the rotary machine is operated as the motor to reverse rotation of the turbine impeller for further increasing the load on the exhaust manifold to add to the engine brake force. While the rotary machine is being operated as the generator, electric power generated thereby is used to charge a battery. When the rotary machine is operated as the motor, the stored electric power is supplied from the battery to the rotary machine.
