For procurement teams supporting Cummins QSK23 engines, the 4062090 diesel fuel injector provides a clearly identified reference for heavy-duty fuel-system maintenance. Used on the QSK23 series 23L inline six-cylinder engine, it receives fuel from the injection system, meters the required quantity, delivers it at the correct timing and atomizes it into fine droplets to support efficient cylinder combustion. Precise metering, stable atomization, fast response and dependable sealing are essential under high-load operation.

This injector reference is commonly searched with Cummins cross numbers 4902827, 4077076, 4088431, 4076533 and 4902828. Related remanufactured or exchange references include 4062090NX, 4062090PX and 4062090RX, while Komatsu-related listings include 6560-11-1110 through 6560-11-1114 and 6560111114. These numbers support sourcing and comparison, but they do not replace fitment verification. Some catalogs also associate this injector family with Komatsu SA6D170E-3 references.

Typical QSK23 equipment coverage includes mining machines, oilfield well-servicing units, generator sets, rail equipment, industrial pumps, compressors and heavy construction machinery. Correct sealing and leak-off control help avoid problems associated with excessive return flow, poor atomization or damaged seals, including hard starting, smoke, low power and high fuel consumption. Before ordering or shipment, buyers should provide the engine serial number, CPL, old injector number, equipment model and injector photo so compatibility can be checked against the supplied unit.
