Cummins 3283160 Fuel Injector Assembly

The Cummins 3283160 fuel injector assembly is a solenoid-actuated high-pressure common rail injector designed for the 8.3L 6C, 6CT, 6CTA, and 6CTAA engine series. It features a multi-hole nozzle (type DLLA140P629) for optimized fuel atomization and combustion efficiency. The injector body is constructed from high-strength alloy steel to withstand peak rail pressures exceeding 1600 bar. It serves as a direct replacement for Cummins OEM part numbers 3283160 and C3283160, ensuring OEM fit, form, and function for heavy-duty on-highway and off-highway equipment. This component is compatible with Bosch interchange numbers 0445120238 and 0986435505. It is engineered for diesel fuel operation in engines such as the Cummins ISC, QSC, ISL, and QSL 8.3L/8.9L platforms. Applications include heavy-duty trucks (Dongfeng Tianlong, Dodge Ram 2500/3500) and construction machinery (Komatsu PC400-7). Each unit undergoes flow testing and calibration to meet Cummins CPL specifications for emissions compliance and engine performance.
