c-ummins Fuel Injector 3083863 is a precision-engineered OEM-grade fuel injector exclusively developed for c-ummins M11 series diesel engines, covering M11 CELECT, ISM11, and QSM11 variants. As a pivotal 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, directly determining the engine’s power output, fuel efficiency, and emission compliance. Crafted from high-strength heat-resistant alloy steel via micron-level precision machining and stringent heat treatment, this injector boasts superior durability, corrosion resistance, and high-temperature tolerance (up to 470℃), making it ideal for harsh working environments characterized by high pressure, heavy dust, and long-term fuel erosion. It integrates advanced CELECT electronic control technology and a high-efficiency hydraulic servo system, enabling ultra-precise fuel metering (error ≤±0.8%) and rapid response, which effectively eliminates fuel supply fluctuations and ensures consistent performance across all engine speed ranges. Its high-precision dual-orifice nozzle, featuring anti-clogging, anti-carbon deposition, and wear-resistant coating, guarantees uniform and fine fuel atomization, promoting complete combustion, reducing fuel consumption by 13-16%, and minimizing harmful emissions (NOx, particulate matter) to meet Euro V, China National V, and EPA Tier 3 emission standards. 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 testing, including pressure tightness, flow rate calibration, and spray pattern inspection, 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.
