Engineered for demanding 23-liter power applications, the Cummins 4087888 diesel fuel injector delivers dependable performance across the QSK23 engine platform. Built for a turbocharged, charge-air-cooled inline 6-cylinder architecture rated from 760–950 hp / 567–708 kW with torque of 2558–2897 lb-ft, this injector supports generator ratings of 545–725 kW prime and 600–800 kW standby, making it a core service part for continuous industrial duty.

The injector features heavy-duty application design, accurate fuel metering, high-pressure injection compatibility, and a stable spray pattern that promotes combustion efficiency and engine protection. Durable construction and effective leakage control support long service intervals, while fast replacement and broad cross-reference coverage (4010165, 4087889, 4928348, 4010025, 4928345, 4928346) simplify sourcing for oilfield, mining, construction, marine auxiliary, and generator maintenance operations. Public listings also connect 4087888 with QSK60 and QSK19 engine series.

Optimal service life depends on clean fuel, clean oil, correct filtration, water control, and proper installation. Replace filters on schedule, drain the water separator, monitor smoke and starting performance, test return fuel flow, and scan ECM fault codes to catch issues such as hard starting, rough idle, black smoke, power loss, and excessive fuel return. Final compatibility must be confirmed by ESN, CPL, original injector number, and injector photo.
