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 extension directly to the electric component thereby fixing the end of the extension to the electric component which is movably arranged within the housing, so that the end of the extension follows each movement of the electric component.

Arrangement for the sealed lead-through of a conductor through the wall of a housing

A fuel injection pump for internal combustion engines which has a moving part supported in a housing bore and on its jacket face on one side, has an exit opening that is under high pressure, and whose bearing is improved by virtue of the fact that on the jacket face of the part or in the wall of the housing bore, at least one pressure compensation is provided. The compensation face is connected to a high pressure source, is disposed on a side of the jacket face of the part which side is remote from the exit opening, and is continuously covered by the wall of the housing bore. As a result, a compensation of the pressure action by means of the pressure field prevailing in the region of the exit opening occurs so that an improved, less damage-prone bearing is produced with a greater high pressure tightness of the moving part.

Fuel injection pump for internal combustion engines

The invention relates to a method and arrangement for preparing a fuel-metering signal M for a diesel engine starting with measured variables such as accelerator pedal position, rotational speed, lambda, exhaust gas temperature or torque. A fuel quantity request MW is pregiven in dependence upon the position of the accelerator pedal. This quantity request MW is supplied to a minimum selector together with a second signal. The output signal M of the minimum selector, in turn, determines the metered fuel. The second signal derives from a precontrol characteristic field 50 in dependence upon the speed. The output signal of the precontrol characteristic field MV is influenced by the controller output signal MR in specific operating conditions.

It is possible in a simple manner, especially in distributor injection pumps, to attain quiet combustion in the idling range of a Diesel engine, without modifying the basic construction of the fuel injection pump by shifting the injection pumping to the last portion of the stroke of the cam driving the pump piston of the fuel injection pump for idling, by means of an injection onset adjusting device, in combination with a determination of injection duration via the closing phase of an electrically controlled valve that relieves the pump work chamber.

Method and apparatus for controlling a high-pressure fuel pumping time

The invention is directed to a method and arrangement for controlling a self-igniting internal combustion engine. The arrangement includes at least one measured-value sensor, electronic control unit for forming a quantity signal for metering fuel, and a control unit for driving individual actuators for each cylinder. The actuators determine the quantity of fuel injected by the pump elements into the cylinders. Under specific conditions, a corrective unit is activated which determines corrective values specific to the cylinders for making the cylinders equal. The open-loop control unit applies the metering signal to the actuators in dependence upon the quantity signal and the corrective values.

A fuel injection arrangement for internal combustion engines, particularly for diesel engines, is indicated, in which the fuel injection is divided into an advance injection and a main injection for the purpose of noise reduction. An advance injection unit (27) is provided for the purpose of proportioning the advance injection quantity and a fuel injection pump of a conventional construction is provided for proportioning the main injection quantity. For an optimal design of the advance injection quantity with respect to noise reduction without influencing the main injection quantity, the advance injection unit (27) comprises a high-pressure storage (28), which is compressed to injection pressure, and at least one solenoid valve (30), which is controlled with respect to time. The advance and main injections are preferably effected via separate nozzle cross sections (21, 22).

Fuel injection pump for internal combustion engines, in particular

The invention is directed to a method and an arrangement for controlling the fuel injection in a high-pressure fuel pump. Magnetic valves determine the fuel quantity to be injected into the engine. The magnetic valve is controlled during the pumping phase of the pumping element in such a manner that first a preinjection and then a main injection is carried out. In specific operating conditions, the control apparatus determines the duration of the drive pulses for the magnetic valve at which a preinjection just takes place. With the duration of the drive pulses as a basis, the control apparatus forms compensating signals for the drive pulses which effect preinjection and stores the same.

The invention relates to a method and arrangement for controlling the fuel metered to an engine and especially to a diesel engine. The engine includes a fuel pump drive by a shaft for which injection start and injection end is fixed by a corresponding control of the electromagnetically actuated valve. The drive pulses for pump-delivery start and pump-delivery end are generated in dependence upon the analog signal of an angle sensor.

A fuel injection pump is proposed in which over a first portion of the supply stroke of the pump piston fuel for the main injection is pumped via a distributor line and a distributor groove into one at a time of a plurality of fuel injection lines. In a second, remaining portion of the pump piston supply stroke, on the same cam flank, fuel is then pre-stored in a reservoir, controlled by a first electrically controlled valve and a second electrically controlled valve and by one of a plurality of longitudinal control grooves, which fuel subsequently, before the beginning of the next main injection determined by the closure of the first electrically controlled valve, is pumped via a second distributor line into the next succeeding injection line.

The injection pump has a pump piston driven with a constant stroke which pumps fuel at injection pressure to an injection nozzle so long as an electrically actuated overflow valve blocks the flow of the fuel overflowing via an overflow conduit to a low-pressure chamber. The overflow valve is a needle valve, the valve needle of which, opening inward toward a pressure chamber that can be placed under injection pressure, by means of a conical closing surface radially defining a needle tip controls a valve seat that widens conically toward the pressure chamber. The cone angle of the closing surface is larger than the cone angle of the associated valve seat and the closing surface forms a sealing edge, the diameter of which is equal to or only slightly smaller than the guide diameter of the guide shank on the valve member. In a preferred embodiment, the needle tip of the valve member has an external contour on its end, adjacent to the closing surface, which directs the fuel flow and reinforces the opening movement. The injection pump is particularly suitable for high-pressure injection in Diesel engines, in order to attain an exact electrical control of the supply onset and supply quantity, if a reservoir chamber defined by a deflecting piston is connected to a high-pressure chamber that includes the pump work chamber.
