DLLA146P2478 is supplied as a remanufactured replacement nozzle. Cross-reference numbers: DLLA146P2478, DLLA140P2483, DLLA133P2491, DLLA128P2490. The nozzle is where atomisation actually happens: fine holes metering fuel into the combustion chamber at high velocity. The rest of the injector decides when and how much; this component decides whether the spray penetrates properly and burns cleanly or leaves unburnt fuel and soot behind. Typical indicators are visible smoke particularly at idle or under light load, hard starting, uneven running, increased consumption and coked deposits on the nozzle tip or in the injector bore. Confirm the diagnosis first: look for contamination elsewhere in the system and verify supply condition. A nozzle that cokes up again within weeks is a symptom of something else, not a defective nozzle. Cleanliness decides the outcome here. Work with the bore and seat scrupulously clean, fit new copper washers and seals, torque to specification, and check whether the engine needs injector coding after reassembly. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
