Engineered for demanding heavy-duty diesel operations, the Cummins 2872544 fuel injector delivers precise fuel metering and reliable performance across the full operating range of ISZ13, ISX12, ISX15, and QSZ13 engine platforms. This common rail injector assembly is built to OEM specifications and is cross-referenced with authorized numbers including 2872544NX, 2872544PX, 2872544RX, 2872289, 209956X, 209956EX, AP55117, R-2872544, and D2872544, giving procurement teams a dependable sourcing solution for fleet and industrial maintenance programs.

Precision Fuel Metering ensures accurate fuel quantity delivery under all operating conditions, while Advanced Nozzle Technology provides optimized spray cone geometry for complete combustion. Superior Durability is achieved through high-strength alloy materials resistant to corrosion, thermal fatigue, fuel contamination, and mechanical wear. Each injector undergoes OEM calibration testing for injection quantity accuracy, leakage control, response speed, and spray consistency, resulting in improved combustion efficiency, higher torque output, lower fuel consumption, reduced particulate emissions, and improved cold-start performance.

Suited to long-haul transportation, mining, construction, agriculture, marine auxiliary, and power generation applications across North America, Europe, Asia Pacific, the Middle East, and Africa, this component supports diverse global fleet requirements. For optimal service life, use OEM fuel filters and ultra-low sulfur diesel, avoid water contamination, monitor rail pressure regularly, and perform periodic injector balance tests.
