    Abstract: When motor vehicles are driven, discontinuities that lead to load spikes arise between overrunning and running under load. The load spikes are avoided by means of a discontinuous increase in fuel quantity, which makes it possible for the engine to come gently to rest in its suspension, to bypass the drive play, and to convert the changes in increased fuel quantity without bucking. By incorporating drag elements into the connection between the arbitrary actuation of an intermediate lever, which affects the fuel injection quantity, and an idling stop, a discontinuous adjustment of the intermediate lever is attained.

    Abstract: A fuel injection pump for internal combustion engines has a fuel-quantity adjusting member, and an adjusting device associated with the adjusting member and operative for altering a possible travel of the fuel-quantity adjusting member as a function of an atmospheric pressure. The device has a pivotally mounted two-armed stop lever against which the fuel-quantity adjusting member can be brought to rest. A circuit is provided with a working element which acts on the stop lever and changes its position or length following a closure and opening of the circuit. The adjusting device has a switching element which is acted upon by the atmospheric pressure and, as a function of atmospheric pressure closes and opens the circuit.

    Abstract: A fuel injection apparatus for definite pilot and main injection in internal combustion engines. A hydraulic auxiliary pump is supplied via a pressure line with fuel from a high-pressure injection pump, which fuel reaches a main injection nozzle and simultaneously drives the hydraulic auxiliary pump. The hydraulic auxiliary pump contains a differential piston comprising a reservoir piston and a pilot injection piston with different diameters and with a spring prestressing such that between the end of supply of the pilot injection and the onset of supply of the main injection, an injection-free spacing stroke (DH) which can be predetermined by means of mechanical stops results, during which spacing stroke (DH) the reservoir piston by retracting further, receives the supply quantity which is pumped during the injection interval by the high-pressure injection pump.

    Abstract: A fuel injection pump for internal combustion engines has a pump piston that is axially and rotationally movable in a cylinder and has a control edge and a diversion edge that defines a recess in the jacket face of the pump piston. To limit and adjust the effective supply stroke, the control edge and the diversion edge cooperate with a control opening in the cylinder, which opening communicates with a fuel-filled low-pressure chamber. To prevent cavitation damage during the diversion process, a pre-diversion groove, which extends approximately parallel to the diversion edge, is provided in the portion of the jacket face of the pump piston defined by the control edge and the diversion edge. It is disposed at a distance from the diversion edge such that immediately before the entry of the diversion edge into the control opening, representing the onset of diversion, it connects the pump work chamber, which is at high pressure, to the control opening.

    Abstract: A fuel injection pump for internal combustion engines having a cup-shaped pump housing and a pump head enclosing the housing. The pump head has a cylinder in which a pump piston, which is set into simultaneous reciprocating and rotary motion by a cam drive, in the course of which it simultaneously acts as a distributor, encloses a pump work chamber that is filled with fuel upon an intake stroke and communicates with one of a plurality of injection lines upon the supply stroke. The resultant reaction forces and moments are supported according to the invention via a roller race supported directly on the pump head, and as a result the induction of force to the pump housing can be avoided.
