c-ummins Fuel Injector 3411845 is a high-performance OEM-grade precision electronic fuel injector specifically engineered for c-ummins M11 series diesel engines, including M11 CELECT, ISM11, and QSM11 variants. As a core component of the engine’s fuel supply system, it undertakes the critical task of atomizing diesel fuel into ultra-fine particles and delivering it to the combustion chamber with precise timing and stable pressure, which directly determines the engine’s power output, fuel economy, and emission compliance. Manufactured from high-strength heat-resistant alloy steel through micron-level precision machining and strict heat treatment processes, this injector boasts excellent durability, corrosion resistance, and high-temperature tolerance (up to 505℃), making it highly adaptable to harsh working environments such as high pressure, heavy dust, long-term fuel erosion, and frequent heavy-load operations. It integrates advanced upgraded CELECT electronic control technology and a high-efficiency hydraulic servo system, enabling ultra-precise fuel metering (error ≤±0.25%) and ultra-fast response, which effectively eliminates fuel supply fluctuations and ensures consistent, stable performance across all engine speed ranges. Its high-precision quad-orifice nozzle, equipped with anti-clogging, anti-carbon deposition, and wear-resistant nano-ceramic coating, ensures uniform and fine fuel atomization, promoting complete combustion, reducing fuel consumption by 19-22%, and minimizing harmful emissions (NOx, particulate matter) to meet Euro V, China National V, and EPA Tier 3 emission standards. The optimized internal flow channel design enhances fuel delivery efficiency and reduces internal resistance, further improving fuel economy and extending service life. As a direct OEM replacement part, it perfectly matches the original engine’s dimensions, installation interface, and electrical parameters, requiring no modific-ations during installation, thus significantly saving maintenance time and labor costs. Each unit undergoes 100% pre-delivery comprehensive testing, including pressure tightness, flow rate calibration, spray pattern inspection, and fatigue resistance testing, adhering to ISO 9001 and TS 16949 quality certific-ations. Tailored to the high-load, long-hour operating characteristics of M11 series engines, it is widely applied in heavy-duty trucks, large excavators, industrial generator sets, heavy construction machinery, and marine auxiliary engines, providing a reliable, efficient, and cost-effective maintenance solution for equipment operators.
