For high-horsepower QSK60 service, Cummins fuel injector 4326640 is a diesel injector assembly intended for accurate fuel metering, stable atomization and controlled injection timing. These functions support clean combustion, balanced cylinder performance and reliable operation in severe-duty environments. The QSK60 is a 60 L, Vee 16-cylinder engine rated at 2,000–2,700 hp (1,491–2,013 kW), making precise fuel delivery an important part of engine service.
For QSK60 platforms using the high-pressure Modular Common Rail system, Cummins electronically controls injection pressure and timing, while an integrated accumulator in each injector helps reduce pressure pulsation and improve stability. The engine series is also listed with HPI and MCR fuel-system options, so this injector should not be selected by engine series alone. Its target markets include mining and marine applications, with generator set, oilfield, rail and industrial power also used as common QSK60 aftermarket search fields.
The primary OE number is 4326640. Numbers 4928349, 4326639, 4088427 and 4010025 are public catalog references rather than universally confirmed interchanges; Alliant Power 4326640 also appears as a public cross-reference. Before shipment, buyers should verify the Engine Serial Number, CPL, old injector label, ECM calibration or code, fuel-system type and equipment model. This verification helps purchasing and maintenance teams align the injector with the actual engine configuration and avoid incorrect fitment.
