1. Product Introduction
A unit pump solenoid valve is a key part in a Unit Injector System (UIS) or Unit Pump System (UPS), commonly used in diesel engines. It controls the precise timing and amount of fuel injected into the combustion chamber.
Function of the Solenoid Valve in a Unit Pump System:
1. Fuel Control – The solenoid valve opens and closes to allow high-pressure fuel into the pump chamber.
2. Injection Timing – It determines when fuel is delivered to the injector.
3. Quantity Regulation – By adjusting the duration the valve stays open, it controls the fuel volume injected.
4. Pressure Build-Up – Works with the pump plunger to generate the high pressure needed for injection.
