Abstract: A fuel injection device of a diesel engine capable of smoothly starting the diesel engine to match an environment around the engine by saving fuel, reducing the exhaustion of carbon dioxide, and suppressing black smoke in starting the diesel engine. A rack is operated by an actuator from a lowest rack position to a starting increased fuel amount position at a lower speed than that at which the rack is operated by the actuator from the lowest rack position to the starting increased fuel amount position at the maximum operating speed. The operating speed of the rack is set in two stages, and the later operating speed of the rack is reduced less than the operating speed of the rack up to a set intermediate rack target value P2. Then, the operating amount of the rack per hour is reduced after the ignition of the engine is recognized. Also, the operating speed of the rack is controlled according to an atmospheric temperature in starting the engine.

Abstract: A pump nozzle for a diesel engine, in which an injection pump element including a pump piston driven by a cam-shaft via a thrust element and a pump element bushing is combined with an injection nozzle to provide a unit to be associated to one motor cylinder. The pump piston is surrounded by a control sleeve which is non-rotatable relative to the pump element busing. The pump piston can be rotated for adjusting its orientation relative to the control sleeve for the purpose of adjusting the supplied amount of fuel. An adjuster for adjusting the amount is disposed at substantially the same level as of the thrust element. The control sleeve is arranged completely within a pump spring, which partly surrounds the pump element bushing. The pump dement bushing is formed integrally with a blind longitudinal bore which receives the pump piston. The pump spring extends from the level of the adjuster for adjusting the amount of fuel to be injected per injection, to the level of the working chamber of the pump piston. This provides an overlapping arrangement of the separate parts of the pump nozzle, so that the structural dimensions of the pump nozzle may be kept small.

Abstract: The control magnet is secured with cap screws on a cap of a control mechanism of an injection pump by means of a holder element, which is a two-armed leaf spring having pre-stressing. The leaf spring has a middle section which comes to rest flush on the magnet core and both arms come to rest flush on a support face of the cap. The spring force spring stressing of the two-armed leaf spring pre-stressed in this manner has an effect of keeping the control magnet secured such that it is not jarred loose even in the event of high acceleration peaks of the injection pump.

Abstract: A control rack for driving the fuel injection quantity control member of an injection pump which supplies fuel to a diesel engine is driven by a magnetic actuator mechanism. The position of the control rack is transmitted to a position sensor via a tie bar which is pivotally supported by a support shaft. The sensor detects a signal corresponding to an actual amount of fuel to be injected. The support shaft is supported by a control member which is pivotally supported. The control member sets a reference position of the support shaft, and hence, sets the relative positional relationship between the control rack and the position sensor. A portion of the control member extends outside a housing, so that the reference position of the tie bar can be corrected outside the housing. The actuator mechanism is controlled by an instruction from a control circuit which calculates an optimal amount of fuel to be injected. A detection signal from the position sensor is used as a feedback signal for calculating an optimal quantity of to be injected.

Abstract: A fuel injection pump for internal combustion engines is disclosed, in which a profiled governor rod of a supply quantity adjusting member, the latter controlled by a final control element, is extended at its end toward the final control element out of the pump housing and is supported in a displaceable manner at the point where it emerges. For the sake of sealing the support point, a cylindrical slide bearing sheath is secured in the pump housing at the location where the governor rod emerges from the pump housing. A cylindrical governor rod guide means which is joined to the profiled governor rod and closes it off or surrounds it in a sealing manner is guided displaceably, with the least possible play, in the slide bearing sheath.

Abstract: In a method and apparatus for controlling the fuel metering for an internal combustion engine, an electrical displacement sensor is used for fuel injection pumps with an injection quantity control element, which is adjusted, via a control lever, proportionally to the electrical displacement sensor, whose displacement change causes an electrical signal proportional to this displacement change, this electrical signal being fed into an electronic control unit for readjusting the injection quantity control element.In order to avoid supply quantity scatter, control can be directed towards a calibration point situated on a supply quantity characteristic of the fuel injection pump, this calibration point preferably being located in the region of the maximum fuel supply quantity, and the output voltage of the electrical displacement sensor can be compared with a specified required value.
