Cummins original 2894920 Common Rail Fuel Injector for ISX15 QSX15 Diesel Engine Replacement for OEM 2897320 5579417 5579415 Auto Engine Parts Car Systems original new injector

Engineered for the demanding operating envelope of Cummins XPI fuel systems, this 2894920 diesel fuel injector delivers the metering precision and durability required by ISX15 and QSX15 heavy duty engines. Manufactured to OEM standards using precision machining technology and micron-level tolerances, the injector supports XPI fuel pressures exceeding 30,000 PSI while maintaining reliable, repeatable fuel delivery across the full duty cycle. It is fully cross-referenced to 2894920PX, 2894920NX, 2894920RX, 5579415, 0445120203, 209989EX, M-2894920 and AP55102 for straightforward fleet sourcing.

Built for severe-duty commercial and industrial applications, the unit combines advanced metallurgy and surface treatment for corrosion resistance and extended service life. Ultra-fine fuel atomization improves combustion efficiency, enhances power output, reduces particulate emissions and lowers engine noise. Designed to support EPA10 and equivalent emission platforms, it maintains compliance while contributing to improved fuel economy and reduced operating costs across CM2250 and CM2350 configurations.

This injector suits heavy duty trucks, mining and oilfield equipment, construction machinery, generator sets, marine auxiliary power and agricultural applications, with vehicle coverage spanning Freightliner Cascadia, Kenworth T680, Peterbilt 579, Volvo VNL and Mack Pinnacle. For optimal performance, replace fuel filters on OEM schedules, use clean ultra-low sulfur diesel, maintain proper fuel pressure and perform periodic injector balance testing.
