c-ummins Fuel Injector 3083849 is a high-performance OEM-grade precision fuel injector specifically engineered for c-ummins M11 series diesel engines, including M11 CELECT, ISM11, and QSM11 variants. As a critical 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 at the optimal timing, directly influencing the engine’s power output, fuel efficiency, and emission levels. Manufactured with high-strength heat-resistant alloy steel through precision machining and strict heat treatment processes, this injector exhibits excellent durability and corrosion resistance, capable of withstanding extreme working conditions such as high temperature (up to 460℃), high pressure, and long-term fuel erosion. It integrates advanced CELECT electronic control technology and an optimized hydraulic servo system, enabling precise fuel metering and fast response, which effectively solves the problem of unstable fuel supply in traditional injectors and ensures consistent performance at different engine speeds. Its high-precision multi-orifice nozzle (with anti-clogging, anti-carbon deposition, and wear-resistant design) ensures uniform and fine fuel atomization, promoting full combustion, reducing fuel consumption by 12-15%, and minimizing harmful emissions such as NOx and particulate matter, complying with 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 and installation interface, requiring no modific-ations during installation, thus saving maintenance time and labor costs. Each unit undergoes 100% pre-delivery testing, including pressure testing, flow rate testing, and spray pattern testing, adhering to ISO 9001 and TS 16949 quality certific-ations. Designed to adapt to the high-load, long-hour working characteristics of M11 series engines, it is widely used in heavy-duty trucks, construction machinery, industrial generator sets, and marine auxiliary engines, providing a reliable and cost-effective maintenance solution.
