Engineered for demanding continuous-duty operation, the 4928349 diesel fuel injector supports the Cummins QSK23 platform, a 23 L inline 6-cylinder, 4-cycle engine with 170 mm bore and 170 mm stroke, turbocharged and charge-air cooled. Cummins lists QSK23 well-servicing ratings from 760–950 hp, with generator prime ratings of 545–725 kW and standby ratings of 600–800 kW. A full engine set normally uses 6 injectors, making this component essential for complete overhauls and scheduled maintenance programs.

This injector delivers precision fuel delivery and controlled atomization, contributing to stable combustion, reliable starting and reduced fuel consumption. Public listings connect part 4928349 with Cummins QSK and K-series engines including QSK23, QSK19, K19, KTA19, QSK45 and QSK60, while broad cross-reference coverage (4326779, 4928346, 4087890, 4902828, 4326781 and more) simplifies global part number searchability. Fitment must always be verified by ESN, CPL and old injector number.

Widely applied across oil and gas, mining, generator, rail, construction and industrial power sectors, this injector suits diesel repair workshops, engine rebuilders, mining contractors, generator service providers and diesel parts wholesalers worldwide. Before replacement, perform fault code reading, return flow, cylinder balance and fuel pressure testing. Use clean fuel, replace filters on schedule and follow official Cummins torque values to maximize service life and reduce downtime.
