The c-aterpillar 10R-7939 fuel injector is a high-precision, heavy-duty common rail injector exclusively designed for the c-aterpillar C6 White Series diesel engines, adhering to c-aterpillar’s stringent OEM quality standards and core principles of reliability, efficiency, and long-term durability. As an authentic OE-grade replacement part (available in both genuine and aftermarket options), it is meticulously engineered to perfectly match the fuel system of C6 White Series engines—equipped with a 6.0L displacement, 145-185kW power range, and compliant with strict emission standards including China National IV, EU Stage IIIA, and US EPA Tier 3. It is also compatible with C6.6 engines as a replacement part (replacement for part number 321-3601). Distinguished by its specialized white anti-corrosion, anti-high-temperature, and anti-oxidation coating, this injector is constructed with high-strength heat-resistant alloy material, enabling it to withstand extreme working conditions such as high temperature, high pressure, and heavy load commonly encountered in construction, mining, and industrial fields. Adopting advanced electronic control common rail technology and c-aterpillar-customized multi-hole nozzles, it achieves ultra-precise fuel atomization and stable injection volume, effectively optimizing combustion efficiency, reducing fuel consumption by 8-12% compared to ordinary injectors, and cooperating with the C6 engine’s ECU to realize intelligent injection control—critical for ensuring low emissions, stable power output, and smooth engine operation. Each 10R-7939 injector undergoes 100% factory qualific-ation testing, including high-pressure sealing detection, precision calibration, and long-term durability verific-ation, fully complying with ISO 9001, Intertek certific-ation, and c-aterpillar’s strict quality assessment criteria. It effectively resolves common faults such as difficult starting, black smoke, power decline, and increased fuel consumption caused by injector aging or damage, providing cost-effective and reliable support for global users of c-aterpillar C6 White Series equipment. With flexible procurement terms, sufficient inventory, and professional technical after-sales service, it has become the preferred replacement part for maintaining the efficient, stable, and low-emission operation of C6 White Series engines.
