Diesel Fuel Injector 7E-6408 7E9983 0R-3052 Diesel Engine Fuel Injector for C/a-t 3512 3516 3508 Excavator

Wuhan Jinhong Auto Parts Co., Ltd. is a manufacturer and exporter of common rail fuel injectors integrating manufacturing,processing and R & D.

 

7E-6408 heavy-duty unit fuel injector adopts integrated thick spring and multi-layer sealing ring design, matching original engine mounting structure perfectly with zero extra machining during replacement. Direct factory supply skips multi-level middle distributors, offering stable low unit price for bulk fleet maintenance and individual equipment repair without cutting core functional standards. Optimized multi-orifice nozzle delivers fine uniform fuel mist under long-duration high-pressure operation, shortening cold start delay and stabilizing power output under variable heavy load shifts. Precision carburized internal needle components resist high-temperature oxidation and fuel impurity abrasion, each finished unit undergoes full flow calibration, sealing and long-cycle aging testing to avoid early dripping or engine jitter. Suited for large stationary generator sets, heavy mining haulers and offshore industrial power units running round-the-clock under extreme working loads, effectively solving hard startup and excessive fuel consumption troubles.
