Suitable for Isuzu 6HK1 04226-E0040/294200-0670 fuel vehicle accessories

          If the fuel metering unit is damaged, the fuel injector injection will be cut off, and the oil inlet metering solenoid valve is completely closed, which can prevent the oil rail pressure from continuing to rise.

        The fuel metering unit is a very precise component, and if you usually use poor quality gasoline filter, it may cause damage to the fuel metering unit. Gasoline filter can filter the moisture and impurities in the gasoline, if the use of inferior gasoline filter, will lead to increased moisture or impurities in the gasoline, which will lead to damage to the fuel metering unit.

       The fuel metering unit is installed in the intake position of the high pressure oil pump. This part can adjust the fuel supply and pressure. This part is controlled by the ecu. If the fuel metering unit is damaged, a fault light will light on the dashboard and the ecu will cut off the fuel injection to the engine. If this failure occurs while driving, a tow truck is required at this time.

      Automotive fuel metering unit, also known as the fuel metering proportional valve, we can be seen as an adjustable size faucet, it is installed in the high-pressure oil pump inlet position, adjusted by the ECU and used to adjust the fuel supply and fuel pressure value.

     The metering unit of the oil pump is a proportional solenoid valve, which can be divided into two kinds from the design structure: one is a normally open metering unit, and the other is a normally closed metering unit.

1, normally open metering unit is mainly suitable for transport vehicles. When the control coil is not energized, the fuel metering unit is switched on to provide the maximum flow of fuel to the oil pump. The ECU increases or decreases the oil volume by changing the cross-sectional area of the high pressure oil pump with pulse signal. In short: the valve is not turned off when it is not powered on, the greater the current, the more the valve is closed!
