• Specification

• Function

1.High - Pressure Fuel Delivery: The plunger reciprocates within the barrel, creating a precise volume of high - pressure fuel. As the plunger moves upward, it closes the inlet port and forces fuel through the delivery valve to the injector, ensuring accurate injection timing and pressure.

2.Flow Control: The barrel features an inlet port and a control helix on the plunger. The helix determines the effective stroke length, controlling the amount of fuel delivered per injection. By rotating the plunger relative to the barrel, the engine management system can adjust the fuel injection quantity based on load and speed.

3.Sealing and Durability: The plunger and barrel are lapped to an extremely fine tolerance, creating a seal that can withstand high pressures (up to 600 bar or more) without additional seals. This precision fit reduces wear and ensures consistent performance over time.
