Engineered for demanding industrial workloads, the Cummins fuel injector 4928346 is a precision component built to support reliable operation of QSK23 series diesel engines. Positioned as an original reference part with broad cross-number coverage, it serves fleets and workshops across oil and gas, mining, generator, rail, construction and industrial power applications. The QSK23 platform is a 23 L inline 6-cylinder, 4-cycle engine with 170 mm bore and 170 mm stroke, using a full set of 6 injectors and rated at 545–725 kW prime and 600–800 kW standby depending on configuration.

This injector delivers controlled atomization, accurate fuel metering and heavy-duty durability that help reduce downtime in continuous-duty environments. Extensive cross-reference support, including 4326779, 4928349, 4087890, 4902828 and 4326781, simplifies global part number searchability and sourcing. Available as new, remanufactured, replacement or aftermarket depending on stock, it is ideal for full-set (6-piece) supply to mining, oilfield service, generator maintenance and industrial remanufacturing operations.

For accurate fitment, confirm the ESN, CPL, old injector number and equipment model before ordering; public listings most strongly connect 4928346 with QSK45 / QSK60, so QSK23 use requires verification. Follow the official Cummins service manual for torque values, keep the injector bore clean, replace all sealing parts, and perform return flow, cylinder balance and fault code testing during diagnosis.
