Patent number: 6574955Abstract: A method for the desulfurization of a nitrogen oxide adsorber of an exhaust gas purification device for a combustion system employs desulfurization phases that are intermittently implemented by a desulfurization control unit. During each desulfurization phase, the carbon monoxide concentration and/or the lambda value of the exhaust gas stream exiting the nitrogen oxide adsorber is recorded. A localized maximum that appears in the recorded course of the carbon monoxide concentration over time, or a downward slope that appears in the established course of the lambda value over time, falling from a temporary plateau value, is employed as criterion for terminating the desulfurization phase. The method may be used, for example, in exhaust gas purification devices in primarily lean-burning vehicle combustion engines.Type: GrantFiled: December 21, 2001Date of Patent: June 10, 2003Assignee: DaimlerChrysler AGInventors: Doris Schröder, Dirk Voigtländer, Michel Weibel, Günter Wenninger, Walter Boegner, Kirsten Hardenberg, Andreas Hertzberg, Günter Karl, Bernd Krutzsch, Renate Marx, Norbert Ruzicka, Christof Schön

Patent number: 6223714Abstract: Switching off a fuel pump of a fuel supply system for the internal combustion engine with the aid of a signal from a retardation sensor of the airbag in the event of a crash in which the motor vehicle is involved is known. To further enhance the safety of motor-vehicle occupants, a method is proposed for an internal combustion engine which has at least one fuel injection valve, a fuel supply system for the at least one fuel injection valve, and a sensor for detecting a crash. After the crash has been detected by means of the sensor, the fuel injection valve is brought into an open position, with the result that fuel is discharged from the fuel supply system of the fuel injection valve into a combustion chamber of the internal combustion engine. The method according to the invention is provided for internal combustion engines with at least one fuel injection valve.Type: GrantFiled: September 21, 1999Date of Patent: May 1, 2001Assignee: DaimlerChrysler AGInventors: Alexander Anderson, Gunter Karl, Rudolf Klein, Stephan Kramer, Peter Lautenschutz, Johannes Leweux, Christoph Lux, Gregor Renner, Klaus Rossler, Matthias Schumacher

Patent number: 6137650Abstract: A hydrodynamic fluid bearing useful in a bearing cartridge which cartridge may be incorporated into a spindle motor or the like, where the bearing includes a shaft, a conical bearing supported on the shaft, and journal bearings located at least on one side and typically both above and below the conical bearing. A sleeve is mounted for rotation relative to the shaft and defines, in cooperation with the shaft, the gaps necessary for both the conical hydrodynamic bearing and the axial, journal bearings. At an end of the shaft, capillary seals are defined between the sleeve and the shaft so that fluid does not escape from the hydrodynamic bearing. The shaft itself includes a central hole, with bores communicating with both the conical bearing and the journal bearings to maintain appropriate pressure balances.In a further desirable feature, in some embodiments the diameter of one end of the shaft can be made greater than the diameter of the other end of the shaft.Type: GrantFiled: December 19, 1997Date of Patent: October 24, 2000Assignee: Seagate Technology L.L.C.Inventors: Gunter Karl Heine, Mohamed Mizanur Rahman, Raquib Uddin Khan, Hans Leuthold

Patent number: 6069768Abstract: A method to create an improved hydrodynamic bearing which is relatively insensitive to changes in load and rotational speed is provided, wherein the hydrodynamic bearing is useful in a spindle motor for a disc drive or the like which is stiffer than known standard spindle motors so that the stability of the system and specifically of the actuator arm and transducer relative to the rotating disc is optimized. The hydrodynamic bearing can also be used as a bearing cartridge or as the cartridge that may be incorporated into a spindle motor or the like, where the bearing includes a shaft and at least two independent bearings each comprising a thrust plate supported on the shaft and a counter plate incorporated in a sleeve which is capable of relative rotation around the shaft.Type: GrantFiled: April 26, 1999Date of Patent: May 30, 2000Assignee: Seagate Technology, Inc.Inventors: Gunter Karl Heine, Raquib Uddin Khan, Mohamed Mizanur Rahman, Hans Leuthold

Patent number: 6069767Abstract: The third dynamic bearing includes a fixed shaft and a sleeve rotating around and surrounding the shaft, and at least first and second thrust plates separated by a portion of the shaft. The shaft includes an axial hole to vent appropriate positions inside the bearing. The axial hole extends from one end of the shaft past at least one of the thrust plates. The axial hole is connected by a radial bore to the bearing gap at a location between the thrust plate closest to that one end of the shaft and the facing counterplate.Alternatively, the axial hole can extend beyond the farthest thrust plate from the one end of the shaft, and can be connected to the bearing gap by a second radial cross-bore. A meniscus forms in the bearing gap on either side of each vent opening, decoupling adjacent bearing sections of the hydrodynamic bearing.Type: GrantFiled: December 19, 1997Date of Patent: May 30, 2000Assignee: Seagate Technology, Inc.Inventors: Raquib Uddin Khan, Gunter Karl Heine, Hans Leuthold, Mohamed Mizanur Rahman

Patent number: 6003306Abstract: Direct-injected engines often operate in broad characteristic field areas with stratified charging, with the harmful emissions not being sufficiently reducible by exhaust recirculation means. Nitrogen oxide molecules are not selectively catalytically reducible In oxygen-rich exhaust during stratified combustion; thus a storage catalytic converter is often located in the exhaust stream to adsorb the resultant nitrogen oxide molecules. In order to initiate desorption and reduction of stored nitrogen oxide molecules, a stoichiometric exhaust composition must be created for a certain operating interval. It was previously assumed that stoichiometric air ratios can only be attained with homogeneous carburetion, so that a switch is made to injection on the intake stroke from fuel injection on the compression stroke.Type: GrantFiled: October 20, 1997Date of Patent: December 21, 1999Assignee: DaimlerChrysler AGInventors: Ronald Kalversberg, Gunter Karl, Roland Kemmler

Patent number: 5997179Abstract: The hydrodynamic bearing gap from one end to the other of the shaft and sleeve combination is effectively separated into sections, with the fluid in each bearing section being contained within that section. The viscosity of the fluid in each bearing section can then be selected to optimize the characteristics of the entire hydrodynamic bearing. Typically, the sections of the bearing adjacent each open end of the bearing would be filled with a fluid with relatively high viscosity. The remaining sections, toward the center of bearing, would typically be filled with a lower viscosity fluid, liquid or gas so that the power consumption within the motor itself would be minimized.Type: GrantFiled: April 22, 1998Date of Patent: December 7, 1999Assignee: Seagate Technology, Inc.Inventors: Raquib Uddin Khan, Gunter Karl Heine, Mohamed Mizanur Rahman

Patent number: 5941208Abstract: Otto internal-combustion engines having one injector respectively per cylinder for the internal mixture formation can be operated at full load or high partial load by fuel injection in the suction stroke of the piston and, at medium or low partial load, with a compression stroke injection. The compression stroke injection, which is advantageous in this load range, because of low average combustion space temperatures and the tendency to form deposits in the combustion space because of residues of liquid fuel and the resulting impaired operating conditions, can partially be carried out only to a limited degree.Type: GrantFiled: November 4, 1997Date of Patent: August 24, 1999Assignee: Daimler-Benz AktiengesellschaftInventors: Andreas Biemelt, Christian Enderle, Stephan Kramer, Klaus Rossler, Bernd Baur, Peter Hohner, Gunter Karl, Roland Kemmler
