c-ummins Injector N14 Series (Part Number: 3411764) Product Details

The c-ummins 3411764 fuel injector is a high-performance, OEM-matched 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 400HP heavy-duty models—one of the most powerful configurations in the N14 series. As a fully optimized finished product, it features three core competitive advantages tailored for high-power heavy-duty applications: high-power adaptive performance, ultra-stable fuel delivery, and c-ummins COS (c-ummins Operating System)-integrated 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. Adhering to c-ummins’ OEM design specifications and rigorous production processes—including advanced manufacturing equipment such as AVL hot test benches and ABB automatic robots, six sigma quality control, and strict component screening using precision instruments from Zeiss and Mahr—this finished injector undergoes a comprehensive manufacturing and testing process to ensure consistent performance and reliability under high-load conditions. Its upgraded high-power solenoid design 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 7-9%, and lowers harmful exhaust emissions even under full-load operation. Crafted from 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 3411764 injector is built to withstand the harshest high-power heavy-duty operating conditions—sustained high pressure, extreme temperatures (up to 440℃), heavy dust, and diesel fuel impurities. As a direct-fit finished replacement, it requires no installation modifications, perfectly matches the N14 400HP 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) 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 400HP-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.
