ABSTRACT:
In a waste heat recovery system for a liquid-cooled internal combustion engine, including a water jacket of a liquid-cooled internal combustion engine in which a portion of the heat generating in the engine is absorbed by an engine cooling liquid, a first heat exchanger is provided for heat absorption from the exhaust gas in which the exhaust gas heat is absorbed thereby and a second heat exchanger is provided for heat recovery in which the waste heat is recovered from the engine cooling liquid carrying the above-mentioned heat. A second circuit for waste heat recovery from the engine includes the first heat exchanger and the second heat exchanger, both being connected to the water jacket in series. The second circuit is adapted to return the engine cooling liquid within the water jacket to the water jacket through the first heat exchanger and the second heat exchanger by a forced circulation force or a natural circulation force. Futhermore, the first circuit for engine cooling comprises an engine cooling radiator which is connected to the water jacket in the manner of a circulation loop. The first circuit is adapted to circulate the engine cooling liquid at least through the water jacket and the engine cooling radiator. The engine cooling radiator is constructed so that the heat radiation therefrom can be controlled by a heat radiation control mechanism.
