c-ummins Injector N14 Series (Part Number: 3411765) Product Details

The c-ummins 3411765 fuel injector is a premium, OEM-compliant finished electronic unit injector specifically engineered for the c-ummins N14 Celect, Celect Plus & STC 14L diesel engine platform (1991–2006), with specialized compatibility for N14 425HP heavy-duty models—the top-tier high-power configuration in the N14 series. As a fully refined finished product, it boasts three core competitive features tailored for extreme heavy-duty applications: extreme high-power adaptability, enhanced thermal stability, and c-ummins COS (c-ummins Operating System)-compliant manufacturing quality, all engineered to meet or exceed c-ummins’ global quality standards, ISO 9001 certification requirements, and the strict quality control protocols of c-ummins’ global manufacturing facilities including CCEC, DCEC, and GCIC. Adhering to c-ummins’ OEM design specifications and rigorous production processes—including advanced manufacturing equipment such as AVL hot test benches, ABB automatic robots, and Atlas tightening tools, six sigma quality control as a problem-solving tool, and strict component screening using precision instruments—this finished injector undergoes a comprehensive manufacturing and testing process to ensure consistent performance and reliability under extreme high-load, high-temperature conditions. Its advanced high-power solenoid design (a precision electromagnetic control component) integrates seamlessly with the engine’s ECM, enabling precise control over injection timing, fuel delivery volume, and atomization effect, which optimizes combustion efficiency, reduces fuel consumption by 7-10%, and lowers harmful exhaust emissions even under long-term full-load operation. Crafted from premium high-strength heat-resistant alloy and hardened steel (strictly screened and tested in c-ummins’ advanced quality laboratories to meet global material standards), the finished 3411765 injector is built to withstand the harshest extreme heavy-duty operating conditions—sustained high pressure, extreme temperatures (up to 450℃), heavy dust, and diesel fuel impurities. As a direct-fit finished replacement, it requires no installation modifications, perfectly matches the N14 425HP engine’s electronic control and fuel supply systems, and each unit undergoes 100% pre-delivery testing (consistent with c-ummins EQA engine quality audit standards and diesel generator set quality inspection specifications) to ensure trouble-free installation and long-term stable operation. Backed by a 12-month limited warranty and professional after-sales support, this finished injector is the ideal choice for maintaining peak performance in N14 425HP-powered heavy-duty trucks, large-scale construction machinery, high-power industrial generators, and heavy mining equipment, delivering exceptional durability, reduced downtime, and consistent extreme high-power output.
