摘要： A fuel injection device is proposed which has a free piston hydraulically driven by a pump piston and controlling the relieving of the pump work chamber. To this end, the free piston is embodied in two parts, comprising a control piston and a relief piston displaceable relative thereto and oriented toward the pump work chamber. The two pistons enclose between them a relief chamber, which at the end of supply can be made to communicate via a relief conduit with a chamber of lower pressure. This free piston is also usable with fuel injection pumps which supply the injection quantity via a long pressure line to the injection nozzles located on the engine; however, it is particularly advantageously usable with a pump/nozzle, in which the injection pump and the injection nozzle are combined into a single component.

摘要： A fuel injection pump in which the injection onset is varied by means of an injection adjuster, which has a two part adjusting piston acted upon by a hydraulic control pressure, which piston is adjustable counter to a restoring spring and by means of a bolt, engages the cam drive of the fuel injection pump in order to adjust the injection onset. To reduce the highest pressure in the high-pressure chamber of the fuel injection pump and to form the course of injection pressure, the adjusting piston is embodied in two parts, with a first piston that is adjustable relative to the second piston counter to a compression spring and the second piston is connected with the bolt. This makes possible a deflection motion of the piston relative to the second piston and a reduction in the pump piston stroke speed.

摘要： 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.

摘要： The invention relates to a fuel injection pump for internal combustion engines having an injection onset adjuster with which the injection onset is adjustable toward "early", for instance in accordance with temperature. In accordance with the invention this adjustment toward "early" is made possible especially in pumps having a load-dependent injection onset adjustment, which preferably exhibit a shift toward "late" up to full load.

摘要： A distributor type fuel injection pump has a rotary magnet regulator (15) to actuate a control member (14) determining the fuel injection quantity, which rotary magnet regulator (15) is driven by a regulating signal produced in dependence on the operational parameters of the internal combustion engine. The rotary magnet regulator (15) is accommodated in a chamber (16) forming part of the pump housing (17) and filled with fuel. A damping device (25) is provided for the purpose of avoiding rotary oscillations of the rotating armature (20) in the rotary magnet regulator (15), which damping device (25) consist of a paddle (26) fixed firmly to the rotating armature (20) and of two separating walls (27,28) provided in the chamber (16). The paddle (26) extends radially from the rotating armature (20) and nearly fills the entire clear cross-section of the chamber (16) available for the swing movement of the paddle. The separating walls (27,28) separate a chamber section (161) comprising the entire range of swing of the paddle (26) from the remaining chamber section (162), whereby however throttle openings ensure a flow of fuel between the chamber section (161) and the chamber section (162) (FIG. 2).

摘要： A fuel injection pump for internal combustion engines having an electromagnetic final control element, which in order to adjust the end or onset of injection engages a control slide, located in the pump interior. Via a control shaft, the final control element chamber is hermetically sealed off from the pump interior in order to keep water contained in the fuel from reaching current-carrying parts of the final control element. As a result, fluid communication exists only via the bearing gap of the slide bearing of the control shaft and the bearing gap functions as a throttle. The throttle forms a water separator, which further reduces the concentration of water in the already small quantity of fuel reaching the final control element chamber through the throttle.
