Patent number: 9382816Abstract: Embodiments of the invention relate to a method for operating a steam cycle process performed in an apparatus having an evaporator or steam generator for the evaporation of a liquid working medium and an expander, which is lubricated by a lubricant, for the performance of mechanical work. The method comprises a) supplying the liquid working medium to the evaporator, in which it evaporates and is fed to the expander in the form of steam; b) supplying an ionic liquid, which at room temperature forms two liquid phases with the liquid working medium, to the expander as a lubricant; and c) separating the ionic liquid forming the lubricant for the expander from the working medium upstream of the evaporator.Type: GrantFiled: May 24, 2011Date of Patent: July 5, 2016Assignee: MAN Truck & Bus AGInventors: Raimund Almbauer, Roland Kalb, Roland Kirchberger, Josef Klammer

Patent number: 9051851Abstract: A method and an apparatus recover heat and convert the heat into mechanical power in a drive system for motor vehicles. A working medium carried in a working medium circuit is evaporated by an evaporator integrated into the working medium circuit by waste heat from an internal combustion engine. The vapor generated is fed to an expansion machine coupled to the internal combustion engine, and the exhaust vapor from the expansion machine is then converted back into the liquid phase in at least one condenser. Accordingly at least one valve, which can be subjected to control by a control device, and a vapor accumulator are integrated into the working medium circuit downstream of the evaporator such that the vapor generated is fed into the vapor accumulator. The vapor stored in the vapor accumulator is fed back at least in part into the working medium circuit to drive the expansion machine.Type: GrantFiled: June 22, 2012Date of Patent: June 9, 2015Assignee: MAN Truck & Bus AGInventors: Gottfried Raab, Josef Klammer

Patent number: 8365527Abstract: A cooling circuit and an independent heat recovery circuit are associated with an internal combustion engine. A coolant is circulated a pump in a first and a second cooling sub-circuit. An increase in pressure in a work medium is achieved within the heat recovery circuit by a pump. This work medium is changed from liquid aggregate state to vaporous aggregate state and back to the liquid aggregate state in heat exchangers. This work medium is divided after the pump into two parallel partial flows and is changed into vaporous state in a first parallel branch in an EGR heat exchanger through which recycle exhaust gas flows and in a second parallel branch in an exhaust gas heat exchanger through flow exhaust gas downstream of the low-pressure turbine flows. This vaporous work medium is then fed to an expander and is then conducted through a cooled condenser and, liquefied again.Type: GrantFiled: December 8, 2009Date of Patent: February 5, 2013Assignee: MAN Nutzfahrzeuge Oesterreich AGInventors: Gottfried Raab, Markus Raup, Josef Klammer
