Patent Number Title Of Patent Date Issued
7937931 Procedure and control unit to operate a diesel engine May 10, 2011
A procedure is introduced to operate a diesel engine, which has a catalytic converter with three-way conversion characteristics. The procedure is characterized thereby, in that if the engine rotational speed increases without in the process exceeding an engine rotational speed thresh
7337658 Method for operating an internal combustion engine March 4, 2008
A method is described for operating an internal combustion engine, in particular of a motor vehicle. In the method, a lean air/fuel mixture is burned in a combustion chamber; nitrogen oxides contained in the exhaust gas are stored in an accumulator-type catalytic converter; a storage
6964266 3/2 Directional-control valve November 15, 2005
The invention relates to a 3/2-port directional-control valve for controlling the injection of fuel in a common rail injection system of an internal combustion engine, with a first switched position in which an injection nozzle is connected to a fuel return and with a second switched
6874476 3/2-way valve April 5, 2005
The invention relates to a 3/2-way valve for controlling the injection of fuel in a common rail injection system of an internal combustion engine, having a first switching position, in which an injection nozzle is in communication with a fuel return, and a second switching position, in
6837451 Seat/slide valve with pressure-equalizing pin January 4, 2005
The invention relates to a 3/2-way valve for controlling the injection of fuel in a common rail injection system of an internal combustion engine, having a first switching position, in which an injection nozzle is in communication with a fuel return, and having a second switching positio
6769634 Injection nozzle August 3, 2004
In a fuel injection nozzle having a nozzle body which body has one first and one second group of injection ports, one first and one second nozzle needle, and one separate pressure chamber for each nozzle needle, so that the injection needles are adjustable independently of one another be
6764058 Control valve and fuel injection valve provided with same July 20, 2004
A control valve and a fuel injection valve provided with same should be produced, in which it is possible to switch from a first operating state to a second operating state inexpensively and with short switching times, without requiring a hydraulic control line. To this end, a control va
6745750 Fuel injection system for internal combustion engines June 8, 2004
A fuel injection system, having a fuel injection valve and a control valve, which control valve has a control valve member that is longitudinally displaceable in a control valve bore. A control valve sealing face is embodied on the control valve member; it cooperates with a control valve
6691935 Injection nozzle February 17, 2004
In an injection nozzle for a fuel injection system, the opening stroke of the nozzle needle is to be limited selectively, so that different injection cross sections can be employed. To that end, the injection nozzle is provided with a nozzle body, a nozzle needle displaceable in the
6637409 Fuel injection device for internal combustion engines October 28, 2003
In a fuel injection system for internal combustion engines, including an electronically triggered control valve with an axial through bore, which is divided by two valve seats into three annular chambers, to which respectively a supply line for fuel at high pressure, a high-pressure line
