🔌 Function

The nozzle is the final element of the fuel injector, spraying finely atomised diesel into the combustion chamber at the correct pressure and spray pattern. Correct atomisation governs combustion quality, power delivery and exhaust emissions.

⚠️ Common Signs of Failure

• Black or excessive smoke from the exhaust under load
• Rough idle, misfire or uneven running on one cylinder
• Hard starting and loss of power
• Increased fuel consumption or diesel knock
• Fuel leakage or dripping from the injector caused by a worn or stuck needle

🛠️ Service Notes

• Work scrupulously clean — a nozzle is a precision component with fine machined orifices, and grit carried in on a fingertip or a rag is enough to ruin it
• Never poke, ream or wire-brush the holes or the seat; if a nozzle is blocked or its spray pattern is disturbed, renew it
• Cap or plug the open fuel or oil way while the nozzle is out so nothing can drop into the passage
• Fit new sealing washers, seals or O-rings, clean the seat in the housing and check that seat is undamaged before the nozzle goes back
• Tighten to the figure and sequence given in the workshop manual for your engine; a nozzle pulled down unevenly or over-tightened will distort and leak
