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 fuel injection pump which has a shutoff device for the fuel supply to the pump work chamber, comprising a magnetic valve, which controls an intake bore to the work chamber of the fuel injection pump. The fuel injection pump further has a relief conduit, which is connected by an annular slide on the pump piston with the suction chamber in order to terminate the effective supply stroke of the pump piston. In order to assure reliable shutoff of the fuel supply to the pump work chamber, a check valve is further disposed in the connection between the pump work chamber and the suction chamber, which check valve is closed, during the intake stroke of the pump piston, with the collaboration of the pressure drop from the suction chamber to the pump work chamber.

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： An improved r.p.m. regulator of a fuel injection pump for internal combustion engines includes an improved control spring mechanism. The control spring mechanism is connected to one end of a control lever which in turn is connected at its other end to a fuel supply quantity setting member. The control lever serves to actuate the fuel supply quantity setting member in accordance with the forces applied to the control lever by the control spring mechanism and an r.p.m.-dependent force applying structure which applies a force to the control lever in opposition to the force applied by the control spring mechanism. The control spring mechanism in one embodiment of the invention includes axially aligned tandem springs mounted between the control lever and a setting lever, a first connecting member and a second connecting member. In another embodiment of the invention a single spring is mounted between the control lever and a setting lever and tandem springs are mounted adjacent to one end of the second connecting member in a perforated pot that is associated with the control lever.

摘要： A fuel injection pump having a hydraulic injection onset adjustment apparatus is proposed, in which a supplementary variation of the injection onset is obtained by means of the variation in pressure deviating from proportionality. This variation is obtained by means of varying a relief channel of a work chamber of the injection adjusting system. The cross-sectional variation is effected in accordance with the hydraulic pressure of the supply pump as well as an adjusting member which varies the initial stress of the restoring spring of the control valve.

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.
