Common Rail Injector 5571980 Condition Fuel Pump Injector Dongfeng 5571980 Fuel Pump Injector For Truck Engine Application High-pressure Common Rail Electronically Controlled Injector

The Cummins 5571980 Fuel Injector Assembly is an original equipment (OE) high-pressure common rail injector designed for advanced diesel engines utilizing Cummins’ XPI (Extra High Pressure Injection) fuel system. As one of the most critical components in modern diesel powertrains, this injector delivers ultra-precise fuel metering and atomization under extreme pressures — directly influencing engine performance, fuel efficiency, emissions compliance, and noise control.

Engineered to meet Euro V/VI, EPA, and China 6 emission standards, the 5571980 supports multiple injection events per combustion cycle (pre-, main, and post-injection), enabling cleaner combustion, reduced particulate matter (PM), and lower nitrogen oxides (NOx). It is widely used across heavy-duty commercial vehicles, industrial machinery, and specialty transport applications where reliability and precision are paramount.
