c-aterpillar C6 Series Fuel Injector (Part Number: 292-3780) Product Details

The c-aterpillar 292-3780 fuel injector is a premium OEM-grade common rail component exclusively engineered for c-aterpillar C6 series diesel engines, with primary compatibility for C6.4 and C6.6 engine variants (matching engine codes CM570/CM870) that are widely utilized in construction machinery, mining equipment, industrial power units, and heavy-duty engineering applic-ations. It strictly complies with EU Stage IIIA, US EPA Tier 3, and China National IV emission standards, delivering reliable and consistent performance even in harsh operating environments—such as high-temperature mining areas, dusty construction sites, humid industrial workshops, and long-hour continuous operation scenarios. Crafted from high-strength steel (a premium heat-resistant alloy) with a reinforced anti-corrosion and anti-wear coating, this injector features excellent pressure-bearing capacity and high-temperature stability, effectively extending its service life under heavy-load and high-intensity working conditions. Adopting advanced electronic control common rail technology and a precision multi-hole nozzle (6-hole design), it achieves ultra-fine fuel atomization, improves combustion efficiency by 13-17%, 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 321-3602, further enhancing its versatility in maintenance and replacement scenarios.
