    • A fuel pump control device is for a fuel supply system for an engine. The system includes a fuel tank, a subtank, a fuel pump pumping fuel in the subtank for supply to the engine, a pressure regulator regulating fuel pressure from the fuel pump within a set pressure, and a jet pump pumping fuel in the fuel tank into the subtank through pumping action by a fuel ejection flow to the fuel tank through a return pipe of the regulator. The device includes a fuel level detecting unit for detecting fuel tank level and a control unit for controlling fuel discharge amount from the fuel pump. The control unit sets jet pump drive correction amount of fuel for driving the jet pump based on the fuel tank level. The control unit increases the fuel discharge amount from the fuel pump by the correction amount to drive the jet pump.
    • 燃料泵控制装置用于发动机的燃料供给系统。 该系统包括一个燃料箱,一个子容器,一个燃料泵,在子容纳槽中抽出燃料以供给发动机;一个压力调节器,调节来自燃料泵的燃料压力在一个设定的压力范围内;一个喷射泵将燃料箱中的燃料泵入 子容器通过通过调节器的返回管的燃料喷射流向燃料箱的泵送作用。 该装置包括用于检测燃料箱液位的燃料液位检测单元和用于控制来自燃料泵的燃料排出量的控制单元。 控制单元基于燃料箱水平设定用于驱动喷射泵的喷射泵驱动校正量的燃料。 控制单元将来自燃料泵的燃料排出量增加到驱动喷射泵的校正量。
