Publication number: 20090136338Abstract: The invention relates to a turbocharger for a combustion engine, in particular of a motor vehicle, with at least one variable turbine geometry turbine, which exhibits a rotor disk and vanes arranged on a vane support, which are spaced apart from each other around the rotor disk in at least one circumferential area, and with an adjuster to select the angular setting of the vanes. It is provided that the vanes (6) are fixed securely to the vane support (5), and exhibit different angular settings (?1, ?2, ?3) relative to the rotor disk (3) in varying sectors (8, 9, 10) of the circumferential area (7), wherein the turbine (2) exhibits a cover device (12) that can rotate relative to the vane support (5) with at least one opening (14, 20) in its jacket surface (16) for purposes of sector selection.Type: ApplicationFiled: November 21, 2008Publication date: May 28, 2009Inventors: Jochen Laubender, Thomas Steidten, Martin Rauscher

Publication number: 20090078233Abstract: The invention concerns a procedure for the braking of a vehicle, especially a motor vehicle, that is operated by a combustion engine, at which the braking torque is initiated into a drive train of the vehicle, by compressing gas in at least one cylinder of the combustion engine during the compression stroke and by discharging the compressed gas at the end of the compression stroke through at least one opened outlet valve from the cylinder. It is provided that the outlet valve is slightly opened before or during the compression stroke and widely opened at the end of the compression stroke.Type: ApplicationFiled: September 23, 2008Publication date: March 26, 2009Applicant: Robert Bosch GmbHInventors: Andre F. CASAL KULZER, Martin A. Rauscher

Publication number: 20090048756Abstract: In a multi-mode, 2-stroke/4-stroke internal combustion engine operation, by switching the engine stroke from 4-stroke operation to 2-stroke operation so that the combustion frequency is doubled, doubling of the engine power is achieved even at the same work output per cycle. In order to meet the demand of extremely high power, the engine operates in 4-stroke boosted SI operation transitioned from 2-stroke HCCI operation at pre-set level of power and crank speed requirements. By combining the multi-stroke (2-stroke HCCI and 4-stroke HCCI) and multi-mode operation (2-stroke HCCI and 4-stroke boosted SI operation), full load range and overall high efficiency with minimal NOx emission are achieved.Type: ApplicationFiled: August 14, 2007Publication date: February 19, 2009Inventors: Sungbae Park, Jasim Ahmed, Han Ho Song, Aleksandar Kojic, Jean-Pierre Hathout, Martin Rauscher, John F.

Patent number: 5667145Abstract: An injection nozzle for diesel engines is disclosed with a direct fuel injection into combustion air in the combustion space having a swirl. The nozzle is constructed as a hole-type nozzle with several injection openings arranged at uniform distances and distributed along the nozzle circumference. In order to further develop such an injection nozzle in a manner which permits shorter injection durations and an improved utilization of the air, an additional injection opening with a smaller diameter is constructed in each case between two adjacent larger injection openings, whereby the overall cross-sectional surface of all injection openings becomes larger without any drifting into one another of the thus formed fuel sprays.Type: GrantFiled: December 22, 1994Date of Patent: September 16, 1997Assignee: MTU-Motoren-Und Turbinen-UnionInventors: Ralph-Michael Schmidt, Christoph Teetz, Martin Rauscher

Patent number: 4335489Abstract: A tensioning device, especially for lashing chains. The device is provided with two link members, movable with respect to each other and having a releasable latch for receiving chain members. At least one link member has a fork-shape, including two legs or arms projecting to extend freely and parallel to each other while being connected by a transverse piece. The link members are held under tension in the closure position, and at least one link member is movable into a releasing position under the force of the connected tension chain. Two spindles are journalled in a double nut, with each having self-binding left and right threads for movement of the link members. A yoke or bracket bridging a suspension opening formed by a hook can be provided, with the hook being pivotable to serve as a link member. The hook is releasably connected with its free end on the yoke or bracket. The hook may be extended beyond the pivot axis thereof.Type: GrantFiled: December 26, 1979Date of Patent: June 22, 1982Assignee: Eisen- und Drahtwerk Erlau AktiengesellschaftInventors: Anton Muller, Martin Rauscher, Gunter Witzel
