    摘要: In a fuel injection pump in which the fuel quantities delivered for injection are controlled by bypassing one part of the fuel from the pump work chamber during the pressure strokes of the pump piston by a control edge of a slidable member that controls a bypass channel in an rpm-dependent manner, for reducing the delivered fuel quantities in the low rpm range at any load condition, said bypass channel is first opened by a throttle and subsequently opened by said control edge.

    摘要: In a fuel injection pump a pump-and-distributor member is axially movably and rotatably disposed between two axially parallel compression springs which are spaced apart 180* with respect to the pump axis and which, through a common yoke, oppose the pressure strokes of said member. A control sleeve is slidably and rotatably arranged on said pump-and-distributor member for altering the starting moment and the period of injection. The angular and axial displacement of the control sleeve is effected by actuating elements connected to said control sleeve and arranged radially outwardly thereof.

    摘要: A load timer mechanism of a fuel injection pump includes a governor shaft, which is secured to a housing, and a governor sleeve, which is axially slidably supported around the governor shaft. The governor shaft includes a fuel relief passage, which is communicated with a low pressure side of the pump and has an outer opening in an outer peripheral surface of the governor shaft, and a first annular groove, which is recessed in the outer peripheral surface of the governor shaft such that the first annular groove is axially displaced from the outer opening. The governor sleeve includes a port, which extends between an outer peripheral surface and an inner peripheral surface of the governor sleeve, and a second annular groove, which is recessed in the inner peripheral surface of the governor sleeve such that the second annular groove is axially displaced from the port.

    摘要: A diesel engine comprises a combustion-temperature control device for adjusting a combustion temperature of the engine depending on an engine operating condition, and an ignition-delay-duration control device for adjusting an ignition delay duration depending on the engine operating condition. An engine-temperature sensor is provided for detecting an engine temperature. During cold-engine warm-up period, an electronic control unit effectively compensates for both the combustion temperature and the ignition delay duration depending on the engine temperature, to reconcile the slow initial combustion in the early combustion stage and the sharp combustion in the middle or later combustion stage and so as to realize a so-called low-temperature premixed combustion with an increased rate of premixed combustion to diffusion combustion under a condition of low combustion temperatures.

    摘要: A fuel injection timing control system for a diesel fuel injection pump with a duty-cycle controlled electromagnetic solenoid valve associated with an injection-timing-control timer piston to change a timer-piston axial position or a set position of a pump plunger in response to a duty cycle of the electromagnetic solenoid valve, comprises a control unit for transiently permitting the entry of a duty cycle of the electromagnetic solenoid valve into a predetermined dead-zone for a predetermined period of time during a fuel injection timing closed-loop control in which an actual injection timing is feed-back controlled toward a target injection timing. In addition, the control unit limits the duty cycle of the electromagnetic solenoid valve to a predetermined limiting value as soon as the predetermined time period has been elapsed, during the fuel injection timing closed-loop control.
