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

557-7633 electronic unit injector adopts integrated hydraulic control and fine multi-hole nozzle structure, with unified mounting aperture to achieve seamless plug-in replacement for matched diesel power units, thickened pressure-resistant housing and composite sealing washers effectively block oil seepage under variable load pressure.
We deliver finished assemblies straight from production lines without multi-level distributors, progressive bulk pricing cuts overall maintenance costs for machinery leasing merchants and repair workshops, stable quotation eliminates hidden logistics surcharges and frequent replacement expense of low-end defective spares.
Carefully calibrated injection pulse angle achieves ultra-fine fuel atomization, fully optimizing air-fuel mixing inside cylinders. It stabilizes engine torque output under heavy loads, suppresses black exhaust fumes and cuts daily diesel consumption while shortening cold ignition delay.
All internal moving core parts undergo mirror surface precision grinding, each finished piece passes long-duration hydraulic cycle testing simulating harsh construction working conditions before packaging. Tight machining tolerance avoids uneven fuel supply and reduces unexpected engine stall faults.
This injection spare part fits medium and large excavation machines, heavy mining equipment and stationary industrial power generators equipped with matched diesel engines, widely selected by mining crews, construction contractors and professional engine overhaul stores for daily faulty component swapping and full engine refurbishment.
