  • Patent number: 6737579
    Abstract: An arrangement for sealed leading of at least one conductor has a housing having a housing wall which surrounds a housing aperture, a closing part which closes the housing aperture, a seal arranged between the closing part and the housing wall which surrounds the housing aperture, at least one conductor track serving as at least one conductor which is pressure-tightly connected with a conductor track carrier formed by an elastic flexible carrier film, the conductor track carrier being routed between the housing and the closing part, the at least one conductor being insulated from outside and being in close contact with the seal in a closing position of the closing part, the closing part being held to the seal by a closing force, a part of the conductor track carrier having an elastic flexible extension which protrudes within the housing, an electrical component which is movably arranged within the housing, the extension being bent for contacting the at least one conductor track thereon on at an end of the ext

  • Patent number: 6152708
    Abstract: A fuel injection pump for internal combustion engines, is proposed, with a distributor pump piston (6), which is supported in a housing bore (5) and on its jacket face, has a distributor groove (12), a filling groove (18), which is connected to a pressure relief chamber, and a pressure compensation surface (36). This filling groove constitutes a first leakage route (39) in the direction of the distributor groove (12) and constitutes a second leakage route (42) in the direction of an annular groove (20) in such a way that the pressure compensation surface, which is otherwise always closed by the inner wall of the bore (5), produces a high-pressure fuel supply by way of the first leakage route (39) in the direction of the pressure compensation surface (36) and this pressure compensation surface (36) is in turn relieved by way of the second leakage route (42) in the direction of the annular groove (20).

  • Patent number: 5520152
    Abstract: A device and a method for controlling an internal combustion engine, in particular a diesel internal combustion engine, having at least one solenoid valve, are described. On the basis of a desired quantity of fuel, an actuation period is determined for the solenoid valve and a signal for fixing the end of actuation is prescribed on the basis of the actuation period. Depending on the operating state of the internal combustion engine, the actuation period is determined either by means of a pump characteristic table or the desired quantity of fuel is used directly as the actuation period. Moreover, depending on the operating state of the internal combustion engine, either an uncorrected or a corrected signal is used for fixing the end of actuation.

  • Patent number: 5386810
    Abstract: In a system and method for controlling a solenoid-valve-controlled fuel-metering device, in particular for a diesel gasoline engine, the duration of delivery is determined based upon the speed value during the preceding metering-in operation.

  • Patent number: 5261374
    Abstract: A method and apparatus for controlling a solenoid-valve-controlled fuel-metering system, especially for a diesel internal combustion engine, provide an electronic control device, which calculates a starting time and/or a stopping time for a solenoid valve based upon at least one of an injection start variable and a feed duration variable. An angle variable is calculated based upon a time variable, taking into consideration at least one of an instantaneous rotational speed and a correction angle.

  • Patent number: 5197439
    Abstract: A method and device for controlling a solenoid-valve-regulated fuel-metering system. Given the desired angular position of a fuel pump camshaft at the beginning of fuel delivery and the desired angular duration of fuel delivery, the method and device of the present invention, while accounting for the switching time of the solenoid valve, determines the trigger instant and shut-off instant for at least one solenoid valve. The present invention achieves more accurate and stable fuel-metering by treating the switching time of the solenoid valve as an angular quantity.

  • Patent number: 5195492
    Abstract: A method and device for the control of a solenoid-valve-controlled fuel-metering system for a diesel gasoline engine provide that the beginning and/or the end of the fuel metering are able to be controlled by trigger instants for the solenoid valve. An angular size is converted into a time quantity by applying at least one rotational-speed value. At least one first time quantity is calculated based upon a first rotational-speed value, and a second time quantity is calculated based upon a second rotational-speed value. A weighted time quantity is determined by generating a mean value from at least the first and second time quantities.
