Patent number: 11479854Abstract: A method of depositing a layer includes measuring a physical property that is related to an air pressure in a reactor chamber of a deposition apparatus. A main gas mixture including a source gas and an auxiliary gas is introduced into the reactor chamber at atmospheric pressure, the source gas including a precursor material and a carrier gas. A gas flow of at least one of the source gas and the auxiliary gas into the reactor chamber is controlled in response to a change of the air pressure in the reactor chamber.Type: GrantFiled: August 20, 2019Date of Patent: October 25, 2022Assignee: Infineon Technologies AGInventors: Olaf Fiedler, Ullrich Hannemann, Andre Horn, Daniel Kai Simon, Sigurd Volker Zehner

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: 11181024Abstract: The invention relates to method for operating an internal combustion engine that has at least two combustion chambers, of which at least one is operated at a substoichiometric air-fuel ratio and of which at least another is operated at a superstoichiometric air-fuel ratio. The outlet of the internal combustion engine is connected to an exhaust gas system in which a three-way catalytic converter is arranged in the flow direction of an exhaust gas through an exhaust gas channel, and an exhaust gas heat-recovery device is arranged downstream from the three-way catalytic converter.Type: GrantFiled: October 25, 2019Date of Patent: November 23, 2021Assignee: VOLKSWAGEN AKTIENGESELLSCHAFTInventors: Falk-Christian Baron Von Ceumern-Lindenstjerna, Stefan Paukner, André Horn, Michael Kaack, Thomas Maischik, Asmus Carstensen

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
