Patent number: 6823629Abstract: A method for eliminating squeaking noises occurring when operating a window lifter for motor vehicles which is driven by an electric motor is proposed. The squeaking noises are detected by a system for evaluating acoustic signals. This system generates for the duration of the squeaking noise a command signal which is delivered to a window lifter control device. This varies the speed of the electric motor within fixed limits, until the system for evaluating acoustic signals no longer detects any squeaking noise or it is recognised that speed variations are ineffective. The method is particularly advantageous if a voice control system which can be used as a system for evaluating acoustic signals is provided in the motor vehicle.Type: GrantFiled: April 16, 2002Date of Patent: November 30, 2004Assignee: ArvinMeritor GmbHInventor: Gerhard Mersch

Patent number: 6823663Abstract: A system and a method for effective NOx and particulate matter control in a diesel or other lean burn internal combustion engine is presented. The system includes a urea-based SCR catalyst having an oxidation catalyst coupled upstream of it and a particulate filter coupled downstream of the SCR catalyst. The particulate filter regeneration method teaches controlling operating conditions to bring the particulate filter temperature in the range where exothermic reaction between hydrocarbon and oxygen occurs. Once this is accomplished, extra hydrocarbons are injected into the exhaust gas entering the particulate filter where they combust and the resulting exotherm regenerates the filter. This method achieves effective particulate matter control while eliminating the risk of thermal damage to the upstream devices and minimizing regeneration fuel economy penalty.Type: GrantFiled: November 21, 2002Date of Patent: November 30, 2004Assignee: Ford Global Technologies, LLCInventors: Robert Henry Hammerle, Christine Kay Lambert, Paul M.

Patent number: 6823664Abstract: An exhaust gas purification device having a NOx absorbent includes a by-pass passage for by-passing the NOx absorbent, an exhaust gas flow rate control portion for regulating both a flow rate of exhaust gas flowing to the NOx absorbent and the flow rate of the exhaust gas bypassing the NOx absorbent, and a reductant addition portion for adding reductant into an exhaust passage upstream of the NOx absorbent. In this device, when it is necessary to discharge sulfur components from the NOx absorbent, a temperature rise control is executed such that a temperature of the NOx absorbent becomes higher than a predetermined temperature. Next, a rich condition control is executed such that an air-fuel ratio of the exhaust gas flowing to the NOx absorbent becomes one of a substantially stoichiometric condition and a rich condition. The flow rate of the exhaust gas to the NOx absorbent during the temperature rise control is controlled so as to be higher than that during the rich condition control.Type: GrantFiled: December 2, 2002Date of Patent: November 30, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koichiro Nakatani, Shinya Hirota, Akira Mikami, Toshiaki Tanaka, Takamitsu Asanuma, Koichi Kimura, Shunsuke Toshioka

Patent number: 6823666Abstract: A process for heating a carbon filter in an exhaust gas system of an internal combustion engine, in particular a diesel engine, with at least one catalytic converter and a carbon filter mounted downstream from the catalytic converter in the direction of flow for accumulating carbon. The catalytic converter mounted upstream from the carbon filter is heated to the extent that the amount of heat from the catalytic converter introduced into the carbon filter heats the carbon filter to the extent that combustion of the carbon is initiated.Type: GrantFiled: May 20, 2003Date of Patent: November 30, 2004Assignee: Audi AGInventor: Bodo Odendall

Patent number: 6823667Abstract: In a method for burning deposited soot particles in a particle filter on an exhaust device of a diesel engine, first of all, in a known way, a catalytic converter produces NO2 from exhaust gas. This NO2 reduces the ignition temperature of soot to such an extent that it burns at normal exhaust-gas temperature. Furthermore, there is provision to add fuel additive, which likewise allows the ignition temperature of the soot to be reduced. The sulphur content in the fuel is determined, and either generation of NO2 or the addition of additive is used as a function of this measurement. This preferably takes place automatically. To determine the sulphur content, it is possible, for example, to use a sulphur sensor in the tank.Type: GrantFiled: February 10, 2003Date of Patent: November 30, 2004Assignee: DaimlerChrysler AGInventors: Tillmann Braun, Oliver Ebelsheiser, Bernd Krutzsch, Klaus-Juergen Marquardt, Michel Weibel, Guenter Wenninger

Patent number: 6823668Abstract: An internal combustion engine waste heat recovery system is provided in which a second heat exchanger, a fifth heat exchanger, a fourth heat exchanger, a third heat exchanger, and a first heat exchanger are disposed sequentially from the upstream side to the downstream side of the flow of exhaust gas in an engine exhaust passage. Water, used as a working medium, is supplied sequentially to the first, second, third, fourth and the fifth heat exchangers. Water having the lowest temperature can be supplied to the first heat exchanger on the most downstream side of the gas flow, to which exhaust gas having a comparatively low temperature is supplied. Water having a comparatively low temperature, which has passed only through the first heat exchanger, can be supplied to the second heat exchanger on the most upstream side.Type: GrantFiled: August 13, 2003Date of Patent: November 30, 2004Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tsuneo Endoh, Masashi Shinohara, Hiroyuki Tanaka

Patent number: 6823671Abstract: The invention relates to a free-piston unit for pumping fluid from a low pressure to a high pressure. The free piston is displaced by a hydraulic part under the influence of the fluid pressure on a plunger which is connected to a combustion piston. The force exerted on the plunger by the fluid pressure in a pressure chamber during the compression stroke can be set using conversion means by setting a third pressure for fluid which is to be displaced via a pressure chamber from the first fluid source to the second fluid source.Type: GrantFiled: June 27, 2002Date of Patent: November 30, 2004Assignee: Innas Free Piston B.V.Inventor: Peter A.

Patent number: 6823673Abstract: A lower control system serves to regulate the flow rate of lifting jack oil, and is installed between a reverse flow valve and an inner oil chamber, regulates the oil flow from the inner chamber to an outer chamber. The lower control system comprises an outer valve body, a steel ball, a spring, and a throttle body. The throttle body has a tapered portion, formed at its front end, and at least one throttling slot way and one lateral slot way, formed respectively on the tapered portion and the circumferential wall thereof. When the jack is not loaded, a reverse flow valve can lift the steel ball so that oil swiftly flows by the throttle body through the lateral slot ways to complete the reverse flow. When the jack is loaded, oil gently flows by the throttle body through the throttling slot ways, leading to a reduction of oil flow rate and a slower descending of the jack.Type: GrantFiled: March 27, 2003Date of Patent: November 30, 2004Assignee: Shinn Fu CorporationInventor: Hsien-Pi Cheng
