Engineered to meet the rigorous demands of heavy-duty diesel powertrains, the 294-3002 Fuel Injector is a precision-built Electronic Unit Injector (EUI) designed as a direct OEM replacement for C13 and C13 ACERT engines. Cross-referenced with 10R-7675, this injector assembly delivers reliable performance across industrial power units, generator sets, marine propulsion systems, on-highway trucks, and off-road construction and mining equipment. Its OEM fit and function ensure seamless integration into existing fuel injection systems without modification.

The injector operates through a five-stage process: low-pressure diesel fuel is delivered from the transfer pump into the injector body; the ECM transmits precisely timed electrical signals to the injector solenoid; internal components generate extremely high injection pressure; fuel is atomized into microscopic droplets; and optimized combustion improves power output, fuel economy, emissions performance, and engine response. Key benefits include precision fuel metering, superior spray pattern, enhanced engine performance, long service life, reduced fuel consumption, lower exhaust emissions, and industrial-grade reliability suited to excavators, wheel loaders, dozers, haul trucks, standby power systems, and workboats.

For optimal operation, clean the injector seat, replace sealing components, verify fuel rail cleanliness, follow OEM torque specifications, prime the fuel system, and conduct leak inspection using diagnostic software. Preventive maintenance includes using high-quality diesel fuel, replacing filters, monitoring injector balance rates, and performing routine ECM diagnostics to address symptoms such as hard starts, excessive smoke, misfire, and rough idle.
