Abstract: A method for operating a fuel injection system of an internal combustion engine is described. The fuel injection system has an injector for metering fuel into a combustion chamber of the internal combustion engine. The injector has an actuator, a control valve and a nozzle needle. In the method, the actuator is supplied a voltage and/or a current during an activation period. The control valve is set into a lifting motion by the actuator. The injector is opened and closed by the nozzle needle, using the lifting motion of the control valve. A further time period is ascertained. The further time period ends at the closing time of the nozzle needle. A function is ascertained, which links the activation period to the further time period. A shortest activation period, for which the nozzle needle opens and produces an injection, is ascertained with the aid of the function. An opening delay period (do1) of the nozzle needle is ascertained as a function of the shortest time period.

Abstract: An injector for injecting fuel into the combustion chamber of an internal combustion engine includes an injector housing, in which a pressure chamber surrounds an insert part. The pressure chamber can be filled with fuel at high pressure via a high-pressure inlet. Via the pressure chamber, a control chamber defined by the insert part and a valve component is subjected to pressure. The valve component is movable inside the insert part, thus executing a stroke motion. A one-piece, metal sealing element is received by a nonpositive connection on the circumference of the insert part is subjected to the high pressure prevailing in the pressure chamber.

Abstract: In all-speed governors controlled by centrifugal force and controlling the full-load fuel delivery quantity of the respective fuel injection pump as a function of boost pressure, the starting fuel delivery is to be reduced at higher operating temperatures of the internal combustion engine to prevent smoke bursts during warm starting. For this purpose, the speed governor has an added support provided in addition to a base support and supported of the later swivelably between two adjusting stops. In addition to a full-load stop arranged on the base support, the added support has an added stop which can be displaced by an adapter unit transversely to the swiveling direction as a function of the boost pressure.
