摘要： To provide for accurate alignment of a housing (10) retaining a fuel injection element (12, 15), and a second housing (23) retaining a control element controlling a function of the fuel injection element, in which the relative positions of the pump housing (10) and of the control element housing (23) are determinative of adjustment and alignment of interengagement between the injection element and the control element, the two housings are provided with attachment screws to attach them securely together, while permitting respective removal, for example for replacement of a sealing gasket (26), and to insure precisely aligned re-assembly, the housings include position locating means (27-34, 35') such as interengaging projection-and-recess means (40, 50, 60, 70, 80, 90, 100, 110; 37, 47, 57, 67, 77, 87, 97, 107) which accurately position the housings with respect to each other, and which are positionable after the housings have been first assembled and aligned to provide for said adjusted and aligned interengagement of the injection element and the control element and reestablishment of said aligned position after separation of the housings. The housings may, also, be spot-welded at selected points beyond break-away zones so that, upon breaking away of the spot welds, they can be separated, with subsequent re-alignment based on the break-away zones.

摘要： An rpm regulator of a fuel injection pump for internal combustion engine includes a single-arm drag lever and an intermediate lever which are bent to define a space into which a compression spring extends. The stroke of the compression spring is limited in both directions by stops defined by the intermediate lever and the drag lever, respectively. The regulator also includes a control spring arrangement which engages one end of the drag lever, a fuel quantity setting member which engages one end of the intermediate lever and controls due to its movement the quantity of fuel delivered by the fuel pump and an rpm governor which exerts an rpm defendent force against the intermediate lever in opposition to the force of the control spring arrangement. With this regulator the pump can deliver an excess fuel quantity for starting purposes and an automatically reduced normal fuel injection quantity when the rpm increases. This result is accomplished without increasing the dimensions of the fuel pump.

摘要： A fuel injection pump having a device for adjusting the injection timing having a work chamber defined by an adjusting piston and communicating via a throttle bore with a pressure source from which the pressure to adjust the adjusting piston is drawn. In order to modify the pressure in the work chamber, the work chamber can be made to communicate via a pressure limiting valve with the relief side of the pump. The control force of the pressure limiting valve is adjustable by means of a stepping motor. An influence on the pressure controlling the adjusting piston is thereby obtained which is restricted to the work chamber.

摘要： A fuel injection system is proposed which has a high-pressure pump, a fuel reservoir determining the injection pressure, and an intermediate piston, during whose first half-stroke meters fuel under low pressure and during a second half-stroke, driven by the reservoir, injects the metered fuel. In order to vary the duration of injection, the pressure in the reservoir is determined either by means of the supply quantity of the high-pressure pump or by means of an appropriate pressure control valve in an outflow conduit.

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.
