c-ummins Injector N14 Series (Part Number: 3411767) Product Details

The c-ummins 3411767 fuel injector is a reliable, OEM-compliant finished electronic unit injector specifically designed for the c-ummins N14 Celect, Celect Plus & STC 14L diesel engine platform (1991–2006), with universal compatibility for N14 400-450HP heavy-duty models—the mainstream high-power configuration widely used in various industrial and transportation fields. As a fully refined and factory-tested finished product, it features three core competitive advantages tailored for versatile ultra-heavy-duty applications: broad power adaptability, reliable performance 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 (verified by Intertek), 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 from global renowned brands (Zeiss, Mahr, Hommel) in c-ummins’ advanced quality laboratories—this finished injector undergoes a comprehensive manufacturing and testing process to ensure consistent performance and reliability under high-load, high-temperature, high-dust, and high-vibration operating conditions. Its precision-machined high-power solenoid design (a premium 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 high-grade 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 3411767 injector is built to withstand the harsh ultra-heavy-duty operating conditions—sustained high pressure, extreme temperatures (up to 460℃), heavy dust, and diesel fuel impurities. As a direct-fit finished replacement, it requires no installation modifications, perfectly matches the N14 400-450HP 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, diesel generator set quality inspection specifications, and professional injector performance testing requirements) to ensure trouble-free installation and long-term stable operation. With a net weight of 5kg and standard size, this finished injector comes with original or customized packaging, backed by a 6-month limited warranty, global delivery (3-7 working days), and professional after-sales support, making it the ideal choice for maintaining peak performance in N14 400-450HP-powered heavy-duty trucks, large-scale construction machinery, high-power industrial generators, and heavy mining equipment, delivering exceptional durability, reduced downtime, and consistent high-power output[2].
