For procurement teams maintaining Cummins QSK engines, the 4076533 fuel injector assembly offers a cross-referenced option for diesel fuel-system servicing. It is presented primarily for QSK23 applications, while supplier data also associates the 4076533 / 4088431 / 4087889 group with QSK23 CM2250 K109, QSK23 CM500, QSK19 CM500, QSK19, and K19 engines. Since configurations differ, confirm compatibility using the engine serial number, CPL, old injector number, ECM or fuel-system type, equipment model, and injector photographs before shipment.
Within the QSK23 High Pressure Injection system, the injector supports fuel metering, high-pressure delivery, atomization, combustion balance, and cylinder protection. Correct fuel quantity and timing under changing load and speed conditions support engine response, fuel economy, and emissions performance. Cummins states that QSK23 high-pressure injection can operate up to 29,000 psi, while G-Drive versions use the HPI-PT full-authority electronic fuel system.
Industrial-grade features include heavy-duty construction, precision metering, high-pressure compatibility, fine atomization, heat resistance, and sealing reliability. Cross-reference support, export-ready packaging, and referenced remanufactured or set-of-six supply options add procurement flexibility. Applications span mining excavators, generator sets, oilfield power units, construction machinery, rail and intermodal power, stationary engines, marine auxiliary power, and fleet spare-parts programs.
