It completely fixes typical long-distance logistics faults including insufficient torque under full trailer load, uneven cylinder combustion, white smoke on cold mornings, frequent DPF forced regeneration and abnormally high fuel consumption caused by worn original injectors. Plug-and-play installation without engine pipeline or ECU modification for European heavy truck repair workshops.

Unique Core Product Competitive Advantages
Highway Optimized Three-Stage Multi-Injection For 13L Large Displacement
Custom DLLA146P1722 multi-hole nozzle delivers segmented pre, main and post injection, optimizing combustion efficiency during constant highway cruising and steep mountain climbing. Effectively cut exhaust soot and lower overall fleet fuel cost compared with agricultural machinery injectors designed for intermittent low-speed field work.
Reinforced Anti-Coking Internal Assembly Adapt To Long-Hour Continuous Operation
Deep carburized alloy needle and valve seat greatly slow carbon deposit accumulation under thousands of kilometers of non-stop cross-border transport, resist sulfur impurities in standard European commercial diesel and avoid early nozzle clogging triggering engine power limitation.
Dedicated DXI13 Truck Bench Full Parameter Calibration Before Shipment
Every injector undergoes long-duration full-load flow stability test, cold start response inspection and solenoid rapid response detection on exclusive DXI13 heavy truck test bench. Each unit locked to original Ren-ault injection curve to eliminate ECM abnormal fault codes after installation.
OEM Consistent Mounting & Electrical Interface Complete With Seal Kit
Identical thread size, sealing surface and 3-pin electrical plug as factory original injector, brand-new high-temperature resistant copper sealing washer pre-equipped per unit, eliminate extra accessory purchasing and shorten vehicle downtime for logistics fleet maintenance centers.
Two Cost-Effective Quality Grades For Different Fleet Operation Modes
Brand-new injectors with all brand-new nozzle, valve and needle core parts for year-round 24/7 cross-border logistics fleets; remanufactured injectors fully replace all worn precision components and re-calibrated, ideal for seasonal construction tipper regular maintenance to control overhaul expenditure.
