Patent number: 11326498Abstract: An exhaust gas heat recovery system for an internal combustion engine has a pump for conveying an operating fluid, an evaporator for converting the operating fluid from the liquid state to the gaseous state, and a condenser for liquefaction of the operating fluid, and having an expansion engine through which the gaseous operating fluid can flow. A sensor is arranged on the expansion engine with which a function of the expansion engine can be monitored. An exhaust system may have such an exhaust gas heat recovery system, and a method for the diagnosis of such an exhaust heat recovery system.Type: GrantFiled: June 11, 2020Date of Patent: May 10, 2022Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: André Horn, Asmus Carstensen, Artur Semke, Thomas Maischik, Thomas Schulenburg

Patent number: 11085347Abstract: A drive unit for a motor vehicle that includes an internal combustion engine, which has a combustion engine and an exhaust gas line, via which exhaust gas can be removed from the combustion engine. A cyclic process device is provided for converting the thermal energy of the exhaust gas into mechanical work in a thermodynamic cyclic process, wherein a working medium with respect to its direction of flow flows through a first heat exchange device, in which a heat transfer from the exhaust gas to the working medium takes place, then flows through an expansion device, in which an expansion of the working medium and thereby the generation of the mechanical work take place, and then flows through a second heat exchange device, in which a heat transfer from the working medium to a cooling medium takes place.Type: GrantFiled: February 10, 2020Date of Patent: August 10, 2021Assignee: Volkswagen AktiengesellschaftInventors: Hardy Naumann, Asmus Carstensen, Artur Semke

Patent number: 11035270Abstract: An internal combustion engine having at least one combustion chamber, the internal combustion engine being connected via the exhaust thereof with an exhaust system. Disposed in the exhaust system is a heat exchanger of an exhaust heat recovery system, which can be used to transfer the waste heat of the exhaust gas to an operating fluid of the exhaust heat recovery system. Furthermore, the internal combustion engine is couplable to an air-conditioning compressor of an air-conditioning circuit. The exhaust heat recovery system has a further heat exchanger, in which the waste heat of a compressed refrigerant of the air-conditioning circuit is transferred to the operating fluid of the exhaust heat recovery system.Type: GrantFiled: June 11, 2020Date of Patent: June 15, 2021Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Artur Semke, Asmus Carstensen, Hardy Naumann, André Horn, Thomas Schulenburg, Thomas Maischik
