Engineered for demanding heavy-duty service, the Cummins 1846350 diesel fuel injector delivers precision fuel metering for QSK15, QSKX15, QSX15, ISX15, and X15 engines. This original-type replacement supports the 15L platform rated at 450–675 hp and 1650–2050 lb-ft, offering fine atomization, stable idle support, and reliable power recovery across industrial diesel applications.
With strong cross-reference value, this injector matches numbers 4076965, 4076912, 574860, 579262, 1529790, 1846351, 4954648, 579261, 1481827, 1521977, 1731091, and 1764365. It serves truck repair, excavator maintenance, generator set service, mining equipment, oilfield machinery, construction equipment, and rail-related engines, backed by global aftermarket supply flexibility and optional testing support.
Proper maintenance sustains performance: use clean diesel fuel, replace fuel filters on schedule, drain the water separator, and keep tanks and lines clean. For QSX15 engines, service oil, filter, and fuel filter at 500 hours per the engine manual. When hard starting, rough idle, black or white smoke, power loss, or high fuel consumption appear, apply fuel-pressure testing, return-flow testing, ECM fault-code reading, and cylinder cut-out testing to confirm injector condition.
