Cummins original For SA6D170E Diesel Engine Fuel Injector Nozzle 47446RX 6560111113 for Engineering Construction Machinery Engine Parts, for heavy duty diesel engine application original new injector

The Cummins QSK60 Fuel Injector 47446RX is a heavy-duty diesel injector assembly intended for QSK60 high-horsepower engine application searches. Designed around the fuel-injection requirements of the 60 L-class V16 platform, it supports maintenance and overhaul work across mining machinery, marine engines, generator sets, rail power, oilfield units, and large industrial diesel installations. The QSK60 platform covers 2000–2700 hp (1491–2013 kW), with HPI or MCR fuel-system options depending on engine configuration.

For QSK60 engines equipped with the high-pressure Modular Common Rail system, electronic control manages injection pressure and timing. Each injector incorporates an integrated accumulator to help reduce pressure pulsation and improve operating stability. These system-level characteristics make correct injector identification essential when sourcing parts for severe-duty service. Product condition and supply format may vary by stock, including genuine, remanufactured, new replacement, or aftermarket replacement options, with original, neutral, export-carton, or wooden-case packaging available.

Public catalogs associate 47446RX with several reference numbers, but these listings are not fully consistent. Numbers including 4928345 and 4088428 appear more directly connected in public listings; other cross numbers should be treated as search references rather than guaranteed official interchanges. Before order confirmation or shipment, buyers should provide the engine serial number, CPL, ECM code or calibration, old injector label and number, fuel-system type, and equipment model. This verification-led approach helps reduce fitment risk and supports accurate B2B procurement.
