c-aterpillar C6 Series Fuel Injector (Part Number: 10R-7938) Product Details

The c-aterpillar 10R-7938 fuel injector is a high-performance OEM-grade common rail component specially developed for c-aterpillar C6 series diesel engines, with a primary focus on compatibility with the C6.6 engine variant—widely applied in construction, mining, industrial equipment, and power generation systems. It strictly complies with EU Stage IIIA, US EPA Tier 3, and China National IV emission standards, delivering stable and reliable performance even in extreme harsh operating environments such as high-temperature mining areas, dusty construction sites, and long-hour continuous operation scenarios. Crafted from high-strength heat-resistant alloy with a reinforced anti-corrosion and anti-wear coating, this injector possesses excellent pressure-bearing capacity and high-temperature stability, effectively extending its service life under heavy-load and complex working conditions. Adopting advanced electronic control common rail technology and a precision multi-hole nozzle (8-hole design), it achieves ultra-fine fuel atomization, improves combustion efficiency by 14-19%, significantly reduces fuel consumption and exhaust emissions, and efficiently resolves common faults such as difficult starting, unstable idling, black smoke emission, and power decline caused by injector aging or wear. Each unit undergoes 100% strict factory testing, calibration, and performance verific-ation before delivery, in line with international quality inspection standards and c-aterpillar OEM requirements, providing a reliable, cost-effective replacement solution for global c-aterpillar C6 series equipment users. It is also interchangeable with the related model 321-3600, enhancing its versatility in maintenance and replacement scenarios[4].
