Cummins original 4902828 Common Rail Fuel Injector 4087887 Replacement for OEM 4076533, 4077076 for QSK23 QSK60 K Series Engine Construction Machinery Parts 1983-2006 original new injector

Accurate fuel delivery is the focus of the Cummins 4902828 diesel fuel injector, listed for selected QSK23 and QSK60 heavy-duty engine applications. Its primary cross references are 4062091 and 4077077, with documented NX, PX and RX suffix variants supporting inquiry matching, quotation and warehouse searches. The injector is intended for diesel fuel injection systems where correct component identification is essential to engine service and repair.

As the final stage of fuel delivery, the injector meters diesel, controls injection timing, atomizes fuel into fine droplets and distributes the spray inside the combustion chamber. Its stated heavy-duty features include high-pressure injection compatibility, accurate fuel metering, a stable spray pattern, durable construction and leakage control. A correctly matched injector supports complete combustion and cylinder balance, helping maintain stable power, smoother idle, better starting, lower fuel consumption and reduced smoke while helping protect pistons, valves, the turbocharger and cylinder liners.

Applications targeted by this product include generator maintenance, mining and construction equipment repair, oilfield service, industrial power units, marine auxiliary power, engine rebuild shops, heavy equipment fleets and diesel parts distribution. For fitment control, buyers should provide the machine model, engine serial number, CPL, original injector number and injector photos before purchase. Final compatibility must be confirmed using these details, together with ECM calibration and supplier stock data; cross-reference numbers alone do not establish interchangeability.
