0445120568 Injector Assembly for construction machinery

advantage

• High-precision matched internal components. The injector body is forged from high strength alloy steel. Core needle valve, nozzle and control valve are carefully selected, processed to micron tolerance. It resists dripping, internal and external oil leakage under continuous high pressure, keeps injection action sensitive and stable, reduces stuck valve risks.
• Optimized 7-hole atomization structure. The 154° spray angle creates fine and uniform mist. Diesel mixes sufficiently with air inside cylinder. Combustion efficiency is greatly improved. It maintains stable power output under heavy intermittent load, cuts black smoke and reduces harmful exhaust emissions.
• Strong adaptability for harsh construction site conditions. Designed for Cummins QSB6.7 diesel engine, fit for excavation, earthmoving and quarry worksites, coping with frequent start-stop and sudden load changes. Stable performance under wide temperature range. Better tolerance to low-quality site diesel, lowering premature failure caused by impurity abrasion.
• Upgraded composite sealing design. Multiple sealing surfaces are optimized to prevent fuel seepage. It helps eliminate common faults like rough idle, slow flameout, carbon accumulation and engine shaking, extending service life of injector assembly.
• Direct replacement with good cost performance. Installation dimensions and interfaces follow original factory specifications. No pipeline modification required. It is an economical aftermarket spare part for engine overhaul and routine maintenance, helping customers cut maintenance expense.

We have built four spare parts warehouses in Xuzhou, Jining, Kunshan and Changsha to provide customers from all over the world with a variety of high-quality spare parts. We can basically ship self-provided spare parts within three days after confirming the order. If the spare parts need to be adjusted or processed, they will be shipped within 7-30 days.
