  • Patent number: 8371107
    Abstract: The invention relates to a device for the regeneration, temperature loading and/or thermal management of a component, assigned to an exhaust system, of an internal combustion engine. The device includes at least one injection valve which injects a fluid, in particular fuel, into the exhaust system, preferably in chatter mode, for example as a function of the pressure of the supplied fluid. The injection valve has a valve head and a valve seat which have geometries designed in such a way that a fluidic force of the supplied fluid acting on the injection valve drops continuously over a stroke of the valve head. The invention also relates to an injection valve having such valve-head and valve-seat geometries and to a corresponding method for the regeneration, temperature loading and/or thermal management of a component, assigned to an exhaust system, of an internal combustion engine.

  • Publication number: 20080264373
    Abstract: A sheathed element glow plug includes an integrated combustion chamber pressure sensor for a self-igniting internal combustion engine for measuring combustion chamber pressures, in particular for combustion chamber signal-based engine control. The sheathed element glow plug has a heating element and a glow plug housing, as well as a glow plug axis. The glow plug housing has a receptacle area for receiving the heating element, a housing body, and at least one flexibility area situated between the housing body and the receptacle area. At least one force measuring element is installed in the glow plug housing.

  • Patent number: 6973918
    Abstract: A fuel injection apparatus having a high-pressure fuel pump and a fuel injection valve for each cylinder. An electrically actuated control valve controls a connection of the pump working chamber to a discharge region. A first injection valve element controls at least one first injection opening and a second injection valve element guided inside the first injection valve element controls at least one second injection opening. Pressure in a control chamber acts on the second injection valve element at least indirectly in the closing direction. By means of a connection controlled by a valve, the control pressure chamber is connected to a pressure region in which a respective pressure increase and decrease are delayed in relation to pressure in the pump working chamber when the control valve respectively closes and opens. The valve is acted on in the opening direction by the pressure prevailing in the pressure region and the closing direction by the pressure prevailing in the pump working chamber.
