  • Patent number: 5148789
    Abstract: In a governor device of a diesel engine, a control rack of a fuel injection pump is adapted to be controllably actuated by a balance between a governor spring and an engine revolution speed responsive means. A speed control member is adapted to be manipulated for adjusting a tension force of the governor spring. A fuel limiting actuation member serves to prevent an excessive fuel flow from being injected when the speed control member is manipulated for a quick acceleration. A quick acceleration state detecting means serves to detect a quickly accelerated state of the engine so as to selectively change over the fuel limiting actuation member to a fuel limiting position and to a fuel limitation cancelling position depending on the lapse of time.
