  • How does fuel metering unit work ?
    2020-08-28

    The working principle of the fuel metering unitSo what exactly does the fuel metering unit do? The fuel metering unit is also called the fuel metering proportional valve. It is installed in the fuel inlet position of the high-pressure fuel pump, used to adjust the fuel supply and fuel pressure value.

    The fuel metering proportional valve is installed at the fuel inlet position of the high-pressure fuel pump and is used to adjust the fuel supply volume and fuel pressure value. And its adjustment requirements are controlled by ECU. When the fuel metering proportional valve is not energized, the fuel metering proportional valve is on and can provide the maximum flow of fuel.

  • How to simply judge the quality of the fuel metering unit?
    2020-10-07

    The role of the automobile metering unit is to control the oil intake and return flow of the high-pressure oil pump, thereby controlling the oil supply of the oil pump plunger to the rail, meeting the set pressure of the common rail system, and forming a closed loop control of the rail pressure with the rail pressure sensor. The internal structure of the fuel metering unit is not complicated. It consists of three parts: a housing with an electromagnetic coil, an upper cover with an oil hole, and a valve core that can move up and down. When it is damaged, just replace it with a new one.

  • How to use the decoder to read the fault code?
    2020-09-16

    The fault code is P1014,The flow rate in the fuel pressure relief valve exceeds the threshold value during reverse driving; The fault code is P0504,The signals of the brake main and auxiliary switches are not credible; P2299: The throttle and brake signals are not credible.

  • Repair and maintenance of suction control valve
    2020-09-10

    Once the electronically controlled engine fails, the fuel injector and fuel metering unit will be replaced frequently. Among them, the suction control valve is often due to the valve body being worn and stuck, which often leads to failures such as difficulty in establishing rail pressure, difficulty in starting, intermittent flameout, and speed limit at 1500 rpm.
