1.Product introduction
EUI (Electronic Unit Injector) and EUP (Electronic Unit Pump) are diesel fuel injection systems used a solenoid-controlled valve, control valve, to control the injection process. The control valve is responsible for regulating the fuel pressure and timing of the injection event by opening and closing according to signals received from the engine control unit (ECU). The EUI/EUP control valve is a critical component of the fuel injection system and must be properly maintained and calibrated for optimal engine performance.
