c-aterpillar C6 Series Fuel Injector (Part Number: 306-9390) Product Details

The c-aterpillar 306-9390 fuel injector is a high-precision OEM-grade common rail component specially developed for c-aterpillar C6 series diesel engines, with primary compatibility for C6.4 and C6.6 engine variants (matching engine codes CM570/CM870/CM2150/CM2350/CM2400) that are extensively used in construction machinery, mining equipment, industrial power units, heavy-duty engineering applic-ations, agricultural machinery, and marine auxiliary equipment. It strictly complies with EU Stage IIIA, US EPA Tier 3, and China National IV emission standards, delivering exceptional reliability and stable performance even in extreme harsh operating environments—such as high-temperature mining zones, dusty construction sites, humid industrial workshops, long-hour continuous operation scenarios, complex agricultural working conditions, and marine high-humidity environments. Crafted from high-strength heat-resistant alloy with a triple-layer anti-corrosion and anti-wear coating (enhanced with marine-grade anti-rust treatment), this injector boasts superior pressure-bearing capacity and high-temperature stability, effectively extending its service life under heavy-load, high-intensity, and multi-scenario 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 16-20%, 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 321-3605, further enhancing its versatility in maintenance and replacement scenarios.
