    摘要： An exhaust gas recirculation (EGR) system for a turbo-charged internal combustion engine is provided. The EGR system includes a recirculation conduit for recirculating a volume of exhaust gas from the exhaust manifold to the intake manifold; a bypass conduit for diverting a flow of intake air around the engine; and an EGR cooler disposed in operative association with the recirculation conduit and the bypass conduit and adapted for cooling the volume of recirculated exhaust gas in the recirculation conduit. The exhaust gas recirculation cooler or heat exchanger is also adapted for concurrently heating the intake air in the bypass conduit. The heated intake air together with the exhaust gas remaining in the exhaust manifold is used to drive the turbocharger. The disclosed embodiment of the exhaust gas recirculation system also includes an air-to-air after-cooler used to cool the compressed intake air. The cool, compressed air is then diverted to the exhaust gas recirculation cooler to cool the recirculated exhaust gas.

    摘要： A turbocharged internal combustion engine includes a supercharging air compressor that delivers compressed air to the engine via a compressed air delivery conduit, the compressor being coupled to an exhaust gas turbine having an inlet connected to the exhaust manifold of the engine via an exhaust gas conduit and an outlet, a bypass conduit connecting the compressed air delivery conduit to the exhaust gas conduit, and is characterized by an energy recovery device comprising an auxiliary vapor generator having a heating fluid side with an inlet connected to the outlet of the exhaust gas turbine and having a heated fluid side with an outlet connected to an inlet of an auxiliary vapor turbine via an auxiliary vapor conduit, and a heat exchanger traversed by the bypass conduit and inserted in the auxiliary vapor conduit for preheating the bypassed compressed air by excess heat of the auxiliary vapor prior to delivering the auxiliary vapor to the auxiliary vapor turbine.
