The Inlet Metering Valve A2C59506225 is generally installed at the fuel supply pump of the fuel injeciton system. It is a fuel-flow-control valve, controlled by the electronic control unit (ECU), which can control the flow of oil entering the high-pressure common rail, thereby controlling the oil flow into the fuel pipe. The good work of this component can not only ensure that the vehicle can run normally but also enable the engine to run in the most fuel -- efficient state to achieve the effect of saving fuel.
