c-ummins Fuel Injector 3083846T is a premium OEM-grade precision component exclusively engineered for c-ummins N14 series diesel engines, including N14 CELECT, N14 CELECT Plus electronic control models and partial mechanical N14 variants. As a critical core part of the engine’s PT (Pressure-Time) fuel supply system, it is designed to atomize diesel fuel into ultra-fine, uniform particles and deliver them to the combustion chamber with precise timing, stable pressure, and optimal distribution—directly governing the engine’s power output, fuel efficiency, and operational reliability. Crafted from high-strength heat-resistant alloy steel with micron-level precision machining, strict heat treatment, and a specialized anti-corrosion, anti-wear coating, this injector boasts exceptional durability, capable of withstanding extreme working conditions such as high temperature (up to 550℃), high pressure, heavy dust, and high humidity. It integrates advanced CELECT electronic control technology (for electronic models) or high-precision mechanical plunger control (for mechanical variants), achieving ultra-accurate fuel metering (error ≤±0.07%) and rapid response (＜0.8ms), effectively eliminating fuel supply fluctuations and ensuring smooth engine operation even under drastic load changes. The high-precision multi-orifice nozzle, treated with anti-carbon deposition and anti-clogging nano-coating, ensures complete fuel atomization, promotes full combustion, reduces fuel consumption by 28-31%, and meets EPA Pre-2002 and relevant industrial emission standards. As a direct OEM replacement part, it perfectly matches the original engine’s installation dimensions, interface, and electrical parameters, requiring no modific-ations during installation, which significantly saves 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. Widely applied in heavy-duty trucks, industrial generator sets, construction machinery, oilfield power modules, and other equipment equipped with c-ummins N14 engines, it provides a reliable, long-lasting, and cost-effective maintenance solution for equipment operators. It is exclusively designed for N14 series engines and is not compatible with ISBE, M11, or other c-ummins engine series, ensuring optimal performance matching and operational safety. As a precision component, its design adheres to the strict working requirements of diesel injectors, ensuring stable injection pressure, reasonable spray cone angle, and rapid fuel cut-off without dripping.
