  • How to judge the quality of the suction control valve?

    If you have a metering valve adjustment device. Use the suction control valve adjusting device (signal generator) on the pump to adjust the driving current of the suction control valve to see the change of rail pressure.The diesel suction control valve can be removed from the pump, and the driving current of the valve can be adjusted by the suction control valve common rail diesel adjusting device (signal generator) to see the movement of the spool.

  • How to deal with pressure limiting valve failure?

    Common rail pressure limiting valve opening failure is one of the most common failures in diesel vehicles. Once the common rail pressure limiting valve opening failure occurs, the engine will enter the limp function. The engine limits the torque.

  • How does fuel metering unit work ?

    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.

  • Bosch Fuel Metering Valve in Common Rail System

    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 remove and install the fuel injection pressure sensor?

    Full explanation what is a fuel pressure sensor, working principle of the fuel pressure sensor, installation method, how to troubleshoot and detect the fuel pressure sensor failure.
    The fuel pressure sensor is also called a fuel pressure regulator, which is used to control the fuel pressure in the fuel circuit, maintain a constant fuel supply pressure from the fuel injector, and send excess fuel back to the fuel tank. Fuel pressure sensors are divided into high pressure fuel sensors and low pressure fuel sensors.

  • The role of common rail pressure sensor

    Common rail pressure sensor is one of the important components of the diesel engine fuel system. A sensor is used to measure the pressure in the fuel rail and provide electrical signals to the electronic control unit.

  • Why is precise machinery so hard to manufacture?

    Why is precise machinery so hard to manufacture?
    Because the production of any precision machinery cannot be produced 100% without error, just as humans cannot produce an absolutely smooth and frictionless surface.

  • High pressure common rail system for diesel engine

    The common rail system is one of the most sustainable fuel injection systems due to its unique advantages. The high-pressure common rail system realizes the separation of pressure build-up and injection process, so that the control process is more flexible, can more accurately realize the precise control of small oil volume, and better realize multiple injections.
