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-term full-load continuous operation of construction and mining equipment, no deformation or internal fuel leakage under harsh vibration conditions.
Adopts original HEUI hydraulic electronic control structure, micro multi-hole precision nozzle assembly with multi-stage variable injection control. Each injector undergoes strict flow, atomization and dynamic balance testing before delivery, realizing uniform fuel atomization, improving combustion efficiency, reducing black smoke and NOx emissions.
Fully follows CAT original machining and calibration standards, consistent internal oil channel size and electromagnetic control parameters with OEM injectors. Direct plug-and-play replacement without ECU parameter modification, perfectly matched with CAT C7 engine.
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.
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 C7 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.
This heavy-duty HEUI diesel fuel injector is specially developed for CAT C7 engine with OEM part number 387-9427, widely applied in CAT 324D/325D/329D excavators and mining articulated trucks. It features alloy forged body, original HEUI control structure, precision multi-stage injection nozzle and factory original calibration data, fully meeting OEM matching standards. It is an ideal core replacement spare part for engine overhaul, greatly cutting equipment downtime and long-term maintenance costs.
