Features & Advantages

3083863

c-ummins Fuel Injector

3083863, 308-3863, 3411758, 3411401, 4026222, 492825, 3081319, 3083849

1. Advanced CELECT electronic control technology achieves ultra-precise fuel metering (error ≤±0.8%) and accurate injection timing, flexibly adjusting parameters according to engine load and speed to adapt to the complex working conditions of M11 series engines; 2. High-strength heat-resistant alloy steel with stringent heat treatment enhances wear resistance and corrosion resistance, extending service life to 12,000+ working hours in harsh high-temperature, high-pressure environments; 3. High-precision dual-orifice nozzle with wear-resistant coating ensures uniform, fine fuel atomization, promoting complete combustion, reducing fuel consumption by 13-16%, and meeting global emission standards; 4. 100% pre-delivery testing (pressure, flow, spray) ensures zero leakage, no dripping, and long-term reliable operation, fully complying with OE performance standards; 5. OEM-compatible design, direct replacement without modific-ation, easy to install and maintain, significantly reducing maintenance time and labor costs; 6. Optimized hydraulic servo system ensures rapid response (＜1.8ms) and stable performance under heavy loads, reducing engine vibration and noise for improved operation comfort; 7. Strong compatibility, suitable for both original and rebuilt M11 engines, perfectly matching the engine's fuel supply system and ensuring consistent power output and fuel efficiency.

Quality & Maintenance

3083863

c-ummins Fuel Injector

3083863, 308-3863, 3411758, 3411401, 4026222, 492825, 3081319, 3083849

6-month standard warranty (extended warranty up to 12 months available); 100% pre-delivery pressure, flow, and spray quality testing to ensure compliance with OEM working requirements and stable performance. Maintenance guidelines: Use clean high-grade low-sulfur diesel (max 10ppm sulfur) to protect internal precision components; replace fuel filters every 6,000-8,000 working hours; inspect for leaks, wear, and carbon deposits every 350 working hours; avoid disassembling the injector without professional guidance to prevent damage to solenoid valves, nozzles, and hydraulic components. Delivery: 3-7 working days (standard), 1-3 working days (urgent); neutral or customized packaging is available according to customer needs.
