c-ummins Fuel Injector 4307516 is a high-performance OEM-quality new aftermarket component exclusively engineered for c-ummins N14 14.0L diesel engines, integrating advanced piezoelectric actuator technology to meet the rigorous demands of heavy-duty applic-ations. As a critical core component of the engine’s fuel supply system, it is precision-manufactured to comply with original c-ummins standards and ISO 9001, TS 16949 certific-ations, ensuring exceptional reliability, fuel efficiency, and emission control. The injector is equipped with a high-precision piezoelectric actuator that enables ultra-fast response and accurate fuel metering (error ≤±0.3%), delivering fuel atomization into ultra-fine droplets (2–6 microns) for complete combustion, which reduces fuel consumption by up to 8% compared to standard injectors. Crafted from nickel-chromium heat-resistant alloy with a tungsten-carbide nozzle tip and reinforced high-temperature seals, it boasts excellent anti-corrosion, anti-wear, and high-temperature resistance, capable of withstanding extreme operating conditions including a working temperature range of -40℃ to 400℃ and a maximum injection pressure of 2500bar. With a net weight of 1.8kg, it is robust and durable, designed to endure heavy vibration, high dust, and continuous heavy-load operation, making it ideal for construction, mining, and oilfield applic-ations. Each unit undergoes 100% pre-delivery testing, including ultrasonic cleaning, pressure tightness, flow calibration, and spray pattern inspection, 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 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[3].
