Engineered for demanding power generation and off-highway duty cycles, the Cummins 4928347 fuel injector delivers precise fuel metering for the QSK23 platform, a 23 L inline 6-cylinder, 4-cycle diesel engine with 170 mm bore and 170 mm stroke, turbocharged and charge-air-cooled design. This engine supports well-servicing ratings of 760–950 hp / 567–708 kW and 2558–2897 lb-ft torque, plus generator ratings of 545–725 kW prime, 600–800 kW standby, and 545–725 kW data center continuous power. Public listings also connect this injector with QSK45, QSK60, and QSK19 applications.

Built for high-pressure injection compatibility, the injector provides a stable spray pattern, effective leakage control, and improved combustion efficiency for reliable engine protection. Durable construction and heavy-duty application design suit oilfield service, mining, construction machinery, industrial power units, and marine auxiliary power. Broad cross-reference coverage—including 4928346, 4928345, 4087889, 4087888, 4010029, and 4088428—simplifies procurement for distributors and rebuild shops.

Service life depends on clean fuel, correct filtration, water control, and proper installation. Replace fuel filters on schedule, drain the water separator, monitor smoke and starting performance, test return fuel flow, and scan ECM fault codes. Final compatibility must be confirmed by ESN, CPL, original injector number, and injector photo to ensure accurate fitment.
