Product Introduction

1. Upper solenoid valve assembly: an ECM controlled solenoid valve that controls the inlet/outlet of high-pressure engine oil; The coil resistance is about 13-16 Ω (high resistance). 2. Hydraulic servo piston oil driven plunger: High pressure oil pushes this large piston, then presses down on the fuel plunger, compressing diesel to generate injection pressure. 3. Fuel plunger pair: Low pressure diesel enters and is pressurized by the servo piston. 4. Nozzle components: C9 nozzles are mostly precision needle valve fittings with 5 holes, and the atomization cone angle matches the C9 combustion chamber. 5. Multiple sets of sealing gaskets: the oil side sealing gasket and diesel side sealing gasket are the most easily damaged and vulnerable parts; Once it fails, there may be engine oil entering diesel or diesel entering the oil pan to dilute the engine oil. 6. External sealing ring, insulation gasket, electrical plug.
