Patent ID: 8434307

Claim:
A system for recovering energy from gases of an internal combustion engine having exhaust gas recirculation, the system comprising: an exhaust gas recirculation valve; an exhaust gas recirculation heat exchanger configured to receive hot exhaust gases from the internal combustion engine and connected to the exhaust gas recirculation valve, the exhaust gas recirculation heat exchanger operable to evaporate a working medium and to produce steam by heat transfer with the hot exhaust gases; a condenser connected to the exhaust gas recirculation heat exchanger to receive the working medium; and an exhaust gas control valve interacting with the exhaust gas recirculation heat exchanger to control a mass flow of exhaust gases from the internal combustion engine that flows through the exhaust gas recirculation heat exchanger, and to provide exhaust gases flowing constantly through the exhaust gas recirculation heat exchanger during all operating phases of the internal combustion engine; wherein the exhaust gas control valve is coupled to the condenser to receive signals from the condenser relating to at least one of temperature and pressure of the working medium leaving the condenser.
