  • Patent number: 7920957
    Abstract: A method for metering fuel into a combustion chamber of an internal combustion engine is provided, in which a fuel quantity to be metered for a combustion is metered by a preinjection and at least one additional injection, and in which, in the operation of the internal combustion engine, quantity errors of the preinjection are ascertained from the signal of at least structure-borne noise sensor. The method is distinguished in that a correction value is formed as a function of the quantity error of the preinjection, and at least one of the additional injections is corrected using the correction value. A control device is also provided that controls the method.

  • Patent number: 7891587
    Abstract: The invention relates to an intermediate plate for a fuel injector, comprising a high-pressure through-hole which connects a high-pressure passage in a valve body and is connected to a high-pressure fuel reservoir, to a high-pressure space in a nozzle body, wherein the intermediate plate is arranged between the valve body and the nozzle body. In order to improve the injection behaviour of a fuel injector provided with the intermediate plate, in particular during multiple injection of small injection quantities, the high-pressure through-hole has a cross-sectional profile which improves the flow through the high-pressure through-hole from the valve body towards the nozzle body and impairs the flow in the opposite direction from the nozzle body towards the valve body.

  • Patent number: 7743645
    Abstract: The invention relates to a method and device for obtaining a determined flow resistance of a flow channel, especially an opening in a component. The method involves the following steps: a liquid flows through the flow channel; a characteristic depending on the flow resistance of the flow channel in the component is determined; and the flow channel is machined by means of a working method until said characteristic reaches a pre-determined nominal value.

  • Publication number: 20090108093
    Abstract: The invention relates to a fuel injector having an injector housing which has a high-pressure fuel connection which is connected outside the injector housing to a central high-pressure fuel source and inside the injector housing to a pressure space. From the fuel injector highly pressurized fuel is injected into a combustion chamber of an internal combustion engine as a function of the pressure in a control space when a nozzle needle opens In order to provide a fuel injector which can be manufactured inexpensively, the pressure in the control space is controlled directly by a magnetic actuator.
