The Cummins QSK60 Fuel Injector 432678 page supports buyers searching for QSK60 diesel injector numbers beginning with 432678. This requested number should be treated as a likely shortened or incomplete public search number, not as a fully confirmed injector part number. Possible full-number candidates include 4326780, 4326781 and 4326784, while related public search numbers include 4928346, 4088428, 4087887, 3766446 and 4902828. The product category covers diesel fuel injectors, injector assemblies and fuel injection nozzle assemblies for Cummins applications.

This injector category targets the Cummins QSK60, officially specified as a 60 L Vee 16-cylinder engine rated at 2000–2700 hp (1491–2013 kW), with TA/TTAA aspiration and HPI/MCR fuel system options. In the QSK60 high-pressure Modular Common Rail system, electronic control of injection pressure and timing supports controlled fuel delivery. Each injector’s integrated accumulator helps reduce pressure pulsation and improve stability, providing a system-level advantage for severe-duty operation.

Typical application searches include mining equipment, marine engines, generator sets, rail power, oilfield power units and industrial power systems. Related listings also associate some injector numbers with QSK23 and QSK45, but compatibility must not be assumed. Before quotation or shipment, buyers should submit the old injector label number, Engine Serial Number, CPL number, ECM calibration or code, fuel system type and equipment model. This verification helps identify the correct full part number and reduces the risk of ordering an unsuitable injector.
