c-ummins Fuel Injector 4307516 is a premium OEM-grade precision electronic fuel injector specifically engineered for c-ummins M11 series diesel engines, including M11 CELECT, ISM11, and QSM11 variants. As a vital core component of the engine’s fuel supply system, it is responsible for atomizing diesel fuel into fine particles and delivering it to the combustion chamber with precise timing, stable pressure, and uniform distribution—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 strict heat treatment, this injector offers exceptional durability, corrosion resistance, and high-temperature resistance (up to 520℃), making it ideal for harsh working environments such as high pressure, heavy dust, long-term fuel erosion, and continuous heavy-load operations. It adopts advanced CELECT electronic control technology and a high-efficiency hydraulic servo system, enabling ultra-precise fuel metering (error ≤±0.15%) and rapid response (＜1.2ms), which effectively eliminates fuel supply instability and ensures consistent performance across all engine speed ranges. Its high-precision dual-orifice nozzle, coated with wear-resistant and anti-carbon deposition nano-ceramic material, ensures uniform and fine fuel atomization, promoting complete combustion, reducing fuel consumption by 22-25%, and minimizing harmful emissions (NOx, particulate matter) to meet Euro V, China National V, and EPA Tier 4 emission standards. The optimized internal flow channel design reduces fuel resistance, improves delivery efficiency, and extends 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 saving significant 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, complying with ISO 9001 and TS 16949 quality certific-ations. Designed for the high-load, long-hour operating characteristics of M11 series engines, it is widely used 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. It is not compatible with ISBE series engine injectors (such as 0 445 120 007) listed in relevant engine model change announcements.
