Fuel metering valve Fuel measurement valve The fuel metering unit is also called the fuel metering proportional valve. It is installed at the oil inlet position of the high-pressure oil pump, and is used to adjust the fuel supply amount and fuel pressure value, and is controlled by the ECU. The control process is influenced by the value measured by the rail pressure sensor. Simply put, the metering unit can be compared to a throttle valve or a faucet that can adjust the size of the agent. Fuel metering units are precision components. Improper maintenance or use of inferior filter elements will often lead to excessive water or impurities in the fuel, which will cause the fuel metering spool to wear or stick, resulting in the engine not working properly. Fuel metering valve 0928400848 can be used on fuel pumps to controls the amount of fuel entering the pump. The fuel metering valve regulates the fuel quantity which is fed to the high-pressure chambers of the high-p…
