Abstract

An internal combustion-electric motor hybrid power plant for an automotive vehicle. The power plant includes an internal combustion engine and a direct current electric motor generator which are connected to a drive shaft for the vehicle. A clutch mechanism is provided to connect the internal combustion engine, the direct current electric motor generator and the drive shaft for selectively engaging and disengaging the drive shaft with the internal combustion engine and the motor generator. A storage battery is electrically connected to the motor generator to supply current to and receive current therefrom. Thermoelectric semi-conductors are arranged to be heated by the waste heat of the internal combustion engine. These thermoelectric semi-conductors are electrically connected to the battery to supply current thereto. The thermoelectric semi-conductors are mounted in contact with the outer surfaces of the exhaust pipe of the internal combustion engine and also with the outer surfaces of the cylinder walls of the engine.

Claims
