How It Works
ECM Signal → Solenoid energizes, opening the control valve.
High-Pressure Fuel enters, pushing the needle valve open.
Fuel Spray atomizes through the nozzle holes into the combustion chamber.
Solenoid De-energizes → Spring pressure closes the needle valve, stopping injection.
Key Features
✔ Electro-Hydraulic Operation — Uses fuel pressure for mechanical actuation.
✔ Precision Nozzle Holes — Optimized for MaxxForce 10 combustion efficiency.
✔ Leakage Fuel Path — Prevents hydraulic lock and returns excess fuel.
✔ Trim Code Dependency — Requires ECM programming for proper fueling.
Common Failure Points
Clogged Nozzle (from contaminated fuel).
Solenoid Coil Failure (electrical issues).
Needle Valve Sticking (carbon buildup).
Internal Leaks (excessive return flow).

| Component | Function & Description |
|---|---|
| 1. Solenoid Valve | - Electrically controlled by the ECM. - Opens/closes to allow high-pressure fuel into the injector nozzle. - Requires precise voltage/current signals. |
| 2. Control Piston | - Hydraulically actuated by fuel pressure. - Moves to regulate needle valve lift. |
| 3. Nozzle Needle Valve | - Precision-machined needle that seals the injector tip. - Lifts when pressurized fuel overcomes spring tension. |
| 4. Multi-Hole Nozzle Tip | - Typically has 6–8 micro-holes for fuel atomization. - Coated for wear resistance. |
| 5. High-Pressure Fuel Inlet | - Connects to the common rail (1,600–2,500 bar). - Filters debris via an integrated micro-filter. |
| 6. Return Line Fitting | - Leakage fuel (from internal clearances) returns to the tank. - Excess flow indicates injector wear. |
| 7. Calibration/Trim Code | - Unique to each injector for ECM programming. - Ensures precise fuel delivery matching. |
| 8. O-Rings & Seals | - Copper washer (nozzle-to-cylinder head seal). - Viton O-rings (for fuel rail & return line connections). |
