Patent number: 7520133Abstract: A thermodynamic engine converts the superheated steam of at least one working medium into kinetic energy using a decompression device. Said engine includes a low-temperature circuit, in which a first working medium is transported through a first heat exchanger and subsequently through the decompression device and a high-temperature circuit, in which a second working medium is transported through a second heat exchanger and subsequently through the decompression device. The first heat exchanger and the second heat exchanger are located in the exhaust system of an internal combustion engine, and the internal combustion engine a coolant circuit can be used to heat the working mediums in separate collection containers.Type: GrantFiled: June 20, 2005Date of Patent: April 21, 2009Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Michael Hoetger, Herbert Clemens, Tobias Haas, Gunnar Freitag, Michael Preis, Raymond Freymann, Andreas Obieglo

Patent number: 7464550Abstract: Motor vehicle comprises a combustion engine with internal combustion of fuel and/or cold-flame product for driving the motor vehicle and thereby producing exhaust gas and an auxiliary power unit comprising an external burner and an expansion machine. A fuel tank with fuel provides energy to the burner and the combustion engine. The motor vehicle has a cold-flame-reactor with means for feeding the fuel from the fuel tank to the cold-flame reactor, and at least a portion of the fuel is pre-combusted to a cold-flame product in the cold-flame reactor.Type: GrantFiled: November 19, 2004Date of Patent: December 16, 2008Assignee: Amovis GmbHInventors: Michael Hoetger, Detlef Wüsthoff, Herbert Clemens

Patent number: 7104063Abstract: The invention relates to a device for producing mechanical energy. Said device contains an internal combustion engine and an expansion engine (20, 21) which is fed with superheated steam from a steam generator. Exhaust gases of the internal combustion engine are injected into the steam generator (24) to use the waste heat thereof. In order to eliminate pollutants and non-burned fuel in the exhaust gases of the internal combustion engine in a simple and effective manner, the steam generator (24) is heated by a non-catalytic burner (16) at a burner temperature of between 1100° and 1300° C. The exhaust gases of the internal combustion engine can be combined with the combustion gases in the burner (16). The after-burning of non-burned fuel and the combustion of pollutants is thus carried out in a burner (16) in a non-catalytic manner.Type: GrantFiled: October 18, 2002Date of Patent: September 12, 2006Assignee: AMOVIS GmbHInventor: Herbert Clemens

Publication number: 20050133002Abstract: The invention relates to a combustion engine (14) for combusting a mixture of a fast burning gas with air in a combustion process generating mechanical and/or electrical power. The engine (14) comprises a cylinder (10; 36) and a piston movable within the cylinder between a top dead center and a bottom dead center (18). The piston (12; 34) and the cylinder form an expansion volume. An injection nozzle (20; 44) is provided for injecting the fast burning gas into the cylinder (10; 36). The cylinder and the piston form an additional cavity (24; 38) at said top dead center in which said fast burning gas is injectable. The shape of the cavity is adapted to the shape of the flame of the combustion process and its size is large enough that no combustion reactions occur at the walls of the cavity.Type: ApplicationFiled: December 17, 2004Publication date: June 23, 2005Inventors: Michael Hoetger, Herbert Clemens, Detlef Wusthoff

Patent number: 6508060Abstract: In a steam motor with a piston engine, the piston engine is included in a closed steam circuit. This steam circuit includes a steam generator, a steam injector for injecting steam into the piston engine, a condenser for condensing the steam emerging from the piston engine to condensed water, and a water feeding pump for feeding the condensed water to the steam generator. The steam generator is heated by hot combustion gas from a combustion unit. The combustion unit burns fuel. The fuel is mixed with fresh air supplied by an air feeding device through a fresh air passage. The fresh air passage usually contains a first heat exchanger for pre-heating the fresh air by heat from the expanded steam emerging from the piston engine, and a second heat exchanger for pre-heating the fresh air by heat from hot waste gas emerging from the steam generator. In order to provide a particularly compact steam motor without adversely affecting the efficiency, a rotary piston engine is used as piston engine.Type: GrantFiled: March 4, 2002Date of Patent: January 21, 2003Assignee: Enginion AGInventors: Herbert Clemens, Michael Hoetger

Patent number: 5671607Abstract: A compression refrigeration machine is provided having ammonia as a refriant and including a condenser, a throttle device, an evaporator device, and a motor-compressor unit. The motor compressor unit includes an electric motor that drives a compressor and may be arranged in a semi-hermetic or hermetic encapsulation. In an hermetic encapsulation, the electric motor is located outside a suction gas stream flowing into the compressor and outside a discharge gas stream exiting from the compressor so that the electric motor is only exposed to an essentially static ammonia atmosphere. The motor-compressor unit and the semi-hermetic encapsulation are composed of materials stable or resistant to ammonia.Type: GrantFiled: November 7, 1995Date of Patent: September 30, 1997Assignee: SEP Gesellschaft Fur Technische Studien Entwicklung Planung mbHInventors: Herbert Clemens, Ulrich Plantikow, Detlef Wusthoff
