c-ummins Fuel Injector 4307516N is a premium OEM-quality new aftermarket component exclusively engineered for c-ummins N14 14.0L diesel engines, specifically optimized for enhanced performance and durability in heavy-duty industrial and automotive applic-ations. As a critical core component of the engine’s fuel supply system, it is precision-manufactured to meet original c-ummins standards and comply with ISO 9001, TS 16949 certific-ations, ensuring exceptional reliability, fuel efficiency, and emission control. The injector features an upgraded electromagnetic actuator with faster response speed and a precision-machined 6-hole nozzle with anti-carbon and anti-clogging nano-coating, delivering ultra-fine fuel atomization (3–7 microns) for complete combustion. This design not only reduces fuel consumption by up to 10% compared to standard injectors but also minimizes carbon deposits and nozzle wear, extending the service life of both the injector and the engine. Crafted from high-strength nickel-chromium heat-resistant alloy with a reinforced tungsten-carbide nozzle tip and high-temperature resistant seals, it boasts superior anti-corrosion, anti-wear, and high-temperature resistance, capable of withstanding extreme operating conditions including a working temperature range of -45℃ to 420℃ and a maximum injection pressure of 2800bar. With a net weight of 1.9kg, it is robust and durable, designed to endure heavy vibration, high dust, and continuous heavy-load operation—making it ideal for construction, mining, oilfield, and industrial generator applic-ations. Each unit undergoes 100% pre-delivery testing, including ultrasonic cleaning, pressure tightness, flow calibration, spray pattern inspection, and fatigue testing, with individual testing reports provided to ensure zero defects before shipment. As a direct bolt-on OEM replacement part, it requires no modific-ations during installation, significantly saving maintenance time and labor costs. It comes with a 12-month OEM standard warranty and professional technical support, supported by fast delivery and flexible packaging options, making it a cost-effective and reliable solution for N14-equipped equipment maintenance. Additionally, the 4307516N model features an upgraded control valve design for more stable fuel metering (error ≤±0.2%), ensuring consistent engine power output even under sudden load changes, which distinguishes it from the standard 4307516 model.
