Patent number: 10858961Abstract: The invention relates to a method for controlling a waste-heat utilization system (20) for an internal combustion engine (10) of a vehicle, wherein the waste-heat utilization system (20) has at least one expander (22), which can transmit torque to the internal combustion engine (10) and which can be bypassed by means of a bypass flow path (25), at least one evaporator (21), and at least one pump (24) for an operating medium, and wherein at least the evaporator (21) is arranged in the region of the exhaust gas system (11) of the internal combustion engine (10). The expander (22), which can be operated in several operating modes, has a driving connection to a secondary drive shaft (19) of the internal combustion engine in at least one operating mode. An operating mode of the waste-heat utilization system (20) is selected by a control device (30) on the basis of at least one input variable and the waste-heat utilization system (20) is operated in said operating mode.Type: GrantFiled: July 11, 2016Date of Patent: December 8, 2020Assignees: AVL LIST GMBH, IVECO S.P.A., FPT INDUSTRIAL S.P.A., MAHLE AMOVIS GMBHInventors: Klemens Neunteufl, Oswald Lackner, Gerald Gradwohl, Michael Bucher, Fabio Cococcetta, Ivan Calaon, Michael Glensvig

Patent number: 8091360Abstract: The invention relates to a drive system for motor vehicles comprising a waste heat-producing internal combustion engine and a circuit for draining off at least partially said waste heat with a working fluid which is relievable in an expansion machine, wherein said working fluid comprises several components, wherein at least one component is transferable into a gas phase by absorbing heat of the internal combustion engine and/or another source inside the drive system which also comprises means for separating the liquid fraction from the working fluid prior to the expansion machine pressure removal. The internal combustion engine can be cooled by a first cooling circuit. A second cooling circuit can be used in such a way that the first cooling circuit is cooled thereby.Type: GrantFiled: July 31, 2006Date of Patent: January 10, 2012Assignee: Amovis GmbHInventor: Michael Hoetger

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
