Cummins ISM11 QSM11 Engine Fuel Injector 3406604 3064881 4026222 3411752 3084589
The 4026222 fuel injector is a core high-pressure electronic fuel injection component exclusively engineered for Cummins M11, ISM11 and QSM11 diesel engines, widely applied in heavy-duty commercial trucks, mining haulers, marine generator sets, construction excavators and stationary power equipment globally.
This unit injector adopts mechanical-electronic integrated design, matching the original Cummins HEUI fuel system standard, delivering precise fuel atomization, stable injection pressure and consistent fuel supply under high-load, high-temperature and dusty harsh working conditions. Many global repair shops, fleet operators and machinery distributors regard 4026222 as the top replacement injector to solve common engine faults including black smoke, insufficient power, rough idle, hard cold start and excessive fuel consumption caused by aged or damaged original injectors.
Our factory supplies three quality grades of 4026222 injectors: brand-new aftermarket replacement, remanufactured tested unit and genuine OEM original version, fully covering different procurement budgets of B2B wholesale buyers from North America, Europe, Australia, Southeast Asia and Africa.
Every finished injector passes multi-layer bench aging test before shipment, completely avoiding inconsistent fuel supply and early failure risks of low-cost untested generic injectors from small workshops.
