c-ummins Fuel Injector 3083622 is a high-performance OEM-grade precision component specifically developed for c-ummins N14 series diesel engines, covering N14 CELECT, N14 CELECT Plus electronic control models and partial mechanical N14 variants. As a vital core part of the engine’s PT (Pressure-Time) fuel supply system, it is engineered to atomize diesel into fine, uniform particles and deliver them to the combustion chamber with precise timing and stable pressure, directly determining the engine’s power output, fuel economy, and operational stability. Crafted from high-strength heat-resistant alloy steel with micron-level precision machining, strict heat treatment, and a special anti-corrosion and anti-wear coating, this injector exhibits exceptional durability, withstanding extreme working conditions such as high temperature (up to 545℃), 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 ≤±0.08%) and rapid response (＜0.9ms), effectively avoiding fuel supply fluctuations and ensuring smooth engine operation under varying load conditions. 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 27-30%, 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 greatly 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 used 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.
