c-aterpillar C6 Series Fuel Injector (Part Number: 10R-7939) Product Details

The c-aterpillar 10R-7939 fuel injector is a premium OEM-grade common rail component exclusively engineered for c-aterpillar C6 series diesel engines, with broad compatibility covering C6.0, C6.4, and C6.6 engine variants that are widely utilized in construction machinery, mining equipment, industrial power units, and heavy-duty transportation. It strictly adheres to EU Stage IIIA, US EPA Tier 3, and China National IV emission standards, delivering exceptional stability and reliability even in the most extreme harsh operating environments—including high-temperature mining zones, dusty construction sites, humid industrial workshops, and long-hour continuous operation scenarios. Manufactured from high-strength heat-resistant alloy with a dual-layer anti-corrosion and anti-wear coating, this injector boasts superior pressure-bearing capacity and high-temperature resistance, effectively extending its service life under heavy-load, high-intensity working conditions. Adopting advanced electronic control common rail technology and a precision multi-hole nozzle (7-hole design), it achieves ultra-fine fuel atomization, improves combustion efficiency by 15-20%, 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, precision calibration, and comprehensive performance verific-ation before delivery, fully complying 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 related models such as 321-3601, further enhancing its versatility in maintenance and replacement scenarios.
