Cummins original Diesel Common Rail Fuel Injector 4902828 for Auto Engine, 4088431 for QSK23 QSK60 QSK60 G3, Cross Reference 4928346, Replacement for 4326780 original new injector

For part-number-led Cummins sourcing, the 4088431 diesel common rail fuel injector is listed for QSK23, QSK60 and QSK60 G3 engine applications, with 4902828 also identified in the product title. Supplied in original new condition, it serves buyers sourcing Cummins fuel-injection components by OE number, engine model or cross reference. The listed cross reference is 4928346, while 4326780 is identified as a replacement reference. These numbers should be checked against the injector being removed before purchase.

For QSK60-related sourcing, engine configuration is an important part of fitment review. Cummins describes the QSK60 as a 60 L V16 diesel engine rated at 2000–2700 hp, with HPI and MCR fuel-system options and marine and mining applications. Its MCR system electronically controls fuel-pump and injector operation for injection pressure and timing, and uses an integrated accumulator at each injector to support pressure stability. This background helps buyers identify the relevant engine and fuel-system configuration without treating every QSK60 injector as interchangeable.

This overview supports procurement for engine maintenance, overhaul and spare-parts distribution, but the listing does not establish universal compatibility. Before ordering, confirm the engine serial number, CPL, old injector number, fuel-system type, calibration, emissions level and injector photographs with the supplier. Also verify whether 4088431, 4902828, 4928346 or 4326780 matches the required part. This verification helps align the injector with the actual engine and service requirement.
