A method and apparatus for utilizing the waste heat energy of an internal combustion engine in which a turbine is driven by the exhaust gases from the engine and drives an electrical generator. In order to permit a direct coupling between the turbine and the generator and to utilize completely the electrical energy recoverable from the waste heat energy, the generator is a synchronous machine with a non-wound rotor, the generator being connected via an electrical converter to an electric motor which is drivingly coupled to the internal combustion engine to relieve the load therein.
A method for utilizing the waste heat energy of an internal combustion engine, said method comprising driving a thermodynamic expansion machine by waste heat from an internal combustion engine, directly driving from said thermodynamic expansion machine, a synchronous machine having a non-wound rotor as an electrical power generator, connecting at least one electrical converter to the output of said generator, the rotational speed of the generator being the same as the expansion machine, driving an electric motor from said generator and delivering output from said motor to said engine to relieve the load thereon.
Apparatus for utilizing the waste heat energy of an internal combustion engine comprising a thermodynamic expansion machine driven by waste heat from an internal combustion engine, electrical generator means drivingly coupled to the expansion machine, said electrical generator means comprising a synchronous generator including a non-wound rotor, electrical converter means connected to said generator and electrical motor means connected to said converter means and drivingly coupled to said internal combustion engine for relieving the load thereon.
