Part-number clarity is essential when sourcing heavy-duty diesel components. The Cummins 4928346 fuel injector is offered as a QSK23 market-reference product for QSK-series engine parts procurement. It receives diesel fuel, controls fuel quantity, injection timing and atomization, delivering a fine spray into the combustion chamber. Correct injector performance supports engine power, smooth idle and efficient combustion. Depending on actual stock, supply may be new, remanufactured, replacement or aftermarket, so the exact condition should be confirmed before ordering.

For sourcing and search purposes, 4928346 is the main listing number. Related references include 4326779, 4928349, 4087890, 4902828, 4326781, 4088431, 4088428 and 4076533. These numbers support cross-reference lookup but do not independently confirm direct replacement. Public listings most strongly connect 4928346 with QSK45 and QSK60 engines, while some marketplace titles also group it with QSK23, QSK45 and QSK60. It should therefore be treated as a QSK23 market-reference injector, not an unconditionally verified fitment.

The QSK23 is a 23 L inline six-cylinder, four-cycle diesel engine used in oil and gas, mining, generator, rail and industrial applications. Related equipment markets include oilfield, construction and industrial engine service. Before shipment, buyers should provide the engine serial number, CPL, old injector number, injector photo and equipment model. This verification supports accurate matching to the actual engine configuration and helps prevent orders based only on shared or neighboring part-number listings.
