パワーピストンが制御されること。 を特徴とする電子制御油圧式ガバナ。[Claims for Utility Model Registration] A power piston connected to a control rack of a fuel injection pump for controlling the amount of fuel to be injected, and a pilot valve for controlling the hydraulic pressure for operating the power piston,
The pilot valve is controlled by an electrical mechanism such as a solenoid, and processes a control rack position detection sensor, a pilot valve position detection sensor, an engine rotation speed detection sensor, an accelerator position detection sensor, and their detection signals to generate a control output. An electronic control unit (CPU) is provided to control the power piston so that the engine rotational speed relative to the accelerator position is regulated according to a predetermined speed fluctuation rate.
