Product Description
Cum-mins XPI Common Rail Fuel Injector 4928421 for ISC8.3 / ISL8.9 / QSL9.3 Medium-Duty Diesel Engine
4928421 XPI high-pressure common rail fuel injector is fully OEM interchange replacement spare part for Cum-mins ISX11.9, ISX12 and QSX11.9 diesel engines equipped with CM2150 and CM2250 ECU modules, fully compliant with EPA10 & EPA13 heavy-duty vehicle emission standards for North American long-haul semi trucks.
Adopting original XPI ultra-high pressure injection technology, this injector is fitted with wear-resistant micro multi-hole alloy nozzle and fast-response integrated solenoid valve. Multi-stage precise split injection achieves micron-level ultra-fine fuel atomization, maintaining stable torque and consistent power output under full-load long-distance transportation. It effectively eliminates typical engine malfunctions: insufficient power, heavy black exhaust smoke, difficult cold startup, rough fluctuating idle speed, excessive fuel consumption, fuel leakage and ECU cylinder misfire fault codes.
Multi-layer high-temperature resistant FKM sealing rings and thickened copper pressure washers withstand long-term high working temperature and violent mechanical vibration of highway trucks and construction machinery.
Each finished injector undergoes comprehensive professional bench calibration to test injection pressure, fuel flow uniformity, spray pattern and electrical signal stability. Every unit comes with exclusive IQA calibration code; professional diagnostic scanner is required to program the matching code into ECU after installation to balance cylinder performance and pass official exhaust emission inspection.
