摘要： A process for delaying the axial movement of the pump piston of a fuel injection pump of an internal combustion engine and fuel injection pump for completing the process are proposed. The fuel injection pump consists of a pump piston placed in a movable and rotating mode within a cylindrical bore of a cylindrical sleeve. The pump piston is designed as a combination piston with a damping piston of larger diameter, which will upon completion of the fuel injection period of the turn with the damping shoulder, border the damping chamber within damping bore of the cylindrical sleeve. This further allows only throttled amounts of fuel to flow through the throttling pintle into the suction chamber; the throttling pintle runs in a longitudinal direction and is located on the damping piston. This will produce supplementary hydraulic capacity extending from the damping shoulder, which has a supporting effect on the pump piston even at high turn speeds, and further allows for capacity increases of the fuel injection pump.

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 quantity measuring apparatus, preferably for a Diesel engine, is proposed in which the course of the fuel pressure is evaluated. A specialized pressure gradient of a first polarity marks the onset of supply or injection, and the maximum of the pressure gradient of the other polarity represents the end of injection or supply. The question of which designation prevails, whether injection onset and end or supply onset and end, is determined by the measurement location, that is, whether it is in the direction of the injection valve or in the direction of the supply element of the fuel supply pump. The injection quantity, for example, may be determined via the integral of the pressure during the metering period. It is recommended, when a piezoelectric pressure receptor is used, that a resistor-capacitor element be switched parallel thereto.

摘要： A control device for varying the supply onset of a fuel injection pump, in which the supply rate at the lower full-load point is increased without overloading the pump at the rated capacity point. A control of this kind is effected by the use of a deflection piston as well as by use of a prestressed check valve. Regulation serving the same purpose can be achieved with the aid of an element pressure sensor and two magnet valves. The control device is intended for use in an internal combustion engine.

摘要： A fuel injection pump for internal combustion engines comprising a pump housing, a distributor piston guided axially and rotatably, a rotating drive shaft supported in the pump housing, a transmission coupling the drive shaft to the distributor piston and a claw clutch and an eccentric disk rolling on a roller race with cams, and a lubricating oil circulation loop, which has a lubricating oil feed line discharging into a lubricating oil groove and a lubricating oil return line that returns from the transmission chamber which is partly filled with lubricating oil. To assure adequate supply of lubricating oil to the heavily loaded drive faces of the claw clutch, there is a flow lubricating oil through the drive shaft from the lubricating oil groove on into the claw clutch; via lubricating oil openings in at least those claw faces of the claw clutch that transmit a torque, the flow emerges into the transmission chamber.

摘要： 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.

摘要： A fuel injection apparatus for internal combustion engines in which beyond a predetermined remaining stroke during the supply stroke of the pump piston, a relief conduit is opened via a control edge. The same control edge closes the relief conduit once again during the intake stroke. During the subsequent effective intake stroke, the quantity of fuel to be injected upon the following compression stroke is metered by means of the electrically actuatable valve. The magnetic valve here is already opened before the closure of the relief conduit by the control edge, so that in the opening phase of the relief conduit, the pump work chamber of the fuel injection apparatus is flushed. In this manner, precise metering of the quantity of fuel to be injected is attained.
