Engine-Specific Fitment (Cummins Dongfeng XPI Platform) |
Engineered specifically for the Cummins Dongfeng XPI engine platform, this common rail diesel fuel injector (main OE 5491515) delivers a precise, factory-matched fit for ISG11.8, ISG12, QSG12, X12, industrial XPI engines, and generator drive units. Every unit is OEM calibrated to the exact flow rate required by these engines, ensuring consistent injection timing, balanced cylinder performance, and reliable operation across demanding duty cycles.
Built with precision-machined nozzles, hardened valve components, and a corrosion-resistant coating, this injector supports ultra-high injection pressure and an optimized spray pattern tailored to the target engine architecture. The result is improved combustion efficiency, enhanced fuel economy, superior cold starting, and stable performance under extreme operating conditions. Verified cross numbers 4307475, 5491515PX, 4307475RX, 4307468, 5461710, 5491531, 5572006, 5491661, and 4384786 simplify sourcing and confirm accurate replacement compatibility.
Ideal for Dongfeng Tianlong, KL, and KC series trucks, dump trucks, cargo and tractor trucks, municipal vehicles, and commercial buses, this injector serves transportation, power generation, mining, and construction fleets worldwide. It directly addresses common issues such as hard start, white or black smoke, misfire, power loss, high fuel consumption, injector leakage, and cylinder imbalance, helping operators reduce maintenance requirements and lower total operating costs.
