Abstract
A hybrid-propulsion car system having one axle driven by an internal combustion engine and another axis driven by an electric motor. The waste heat of the internal combustion engine is absorbed by the engine cooling fluid, and is then heat exchanged with an evaporative fluid in a closed circuit. The evaporative fluid is vaporized by the heat of the engine cooling fluid in order to drive an expander which in turn drives an electric generator. The electric generator supplies current to a storage battery and to the electric motor.
