1. High-Strength Alloy Forged Body

   The injector main body adopts high-precision alloy steel integral forging, excellent resistance to high temperature and ultra-high fuel pressure. Stable performance under long-distance continuous heavy-load transportation, no deformation or internal fuel leakage under harsh road vibration conditions.

2. Ultra-Precision Multi-Stage Injection Nozzle Assembly

   Equipped with micro multi-hole precision nozzle assembly, multi-stage variable injection control structure. Each injector undergoes strict flow, atomization and dynamic balance testing before delivery, achieving fine fuel atomization, improving combustion efficiency, lowering black smoke and NOx emissions.

3. 100% OEM Dimensional & Calibration Standard

   Fully follows Cumm ins original machining and calibration standards, consistent internal oil channel size and injection control parameters with OEM injectors. Direct plug-and-play replacement without ECU parameter modification, perfectly matched with Cumm ins N14 engine.

4. Multi-Layer High Pressure Sealing System

   Multi-layer composite fluorine rubber sealing rings are installed at all oil circuit joints, with outstanding oil resistance, high temperature resistance and anti-aging performance. Effectively prevent internal and external fuel leakage, extend injector service cycle and reduce maintenance frequency.

5. Optimized Power & Fuel Economy Performance

   Accurate control of injection timing and fuel delivery volume, effectively solve engine power shortage, unstable speed, excessive fuel consumption and exhaust black smoke faults. Maintain original power output of N14 engine, reduce cylinder liner and piston wear.

Delivery: Multiple reliable shipping channels available, including air freight and sea freight. Each injector is individually oil-sealed and packed with anti-collision foam, complete inspection documents and traceable tracking number for global delivery.

Import duties, local consumption taxes and extra handling fees are not included in quoted price and freight. Buyers shall bear all related fees in accordance with local customs regulations.
