c-aterpillar C6 Series Fuel Injector (Part Number: 320-0677) Product Details

The c-aterpillar 320-0677 fuel injector is a high-precision OEM-grade common rail component specifically designed 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). It is widely applied in construction machinery, mining equipment, industrial power units, and heavy-duty engineering applic-ations, strictly complying with EU Stage IIIA, US EPA Tier 3, and China National IV emission standards. Crafted from high-strength heat-resistant alloy with a double-layer anti-corrosion and anti-wear coating (enhanced with anti-oxidation treatment), this injector boasts exceptional pressure-bearing capacity and high-temperature stability, adapting perfectly to harsh working environments such as high-temperature mining zones, dusty construction sites, humid industrial workshops, and long-hour continuous operation scenarios. Adopting advanced electronic control common rail technology and a precision 8-hole nozzle design, it achieves ultra-fine fuel atomization, improves combustion efficiency by 17-21%, significantly reduces fuel consumption and exhaust emissions, and effectively resolves common faults like 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 meeting c-aterpillar OEM quality standards and providing a reliable, cost-effective replacement solution for global c-aterpillar C6 series equipment users. It is also interchangeable with related models such as 321-3607, further enhancing its versatility in maintenance and replacement scenarios.
