Product Description

cum-mins XPI High Pressure Common Rail Fuel Injector 1933612 for ISX15 / QSX15 / X15 Heavy Duty Diesel Engine

This high-performance XPI high-pressure common rail fuel injector 19933612 is a fully OEM interchangeable replacement spare part matching Cum-mins ISX11.9, ISX12 and QSX11.9 diesel engines fitted with CM2150 and CM2250 control modules. It fully complies with EPA10 and EPA13 emission standards applied on North American long-haul semi trucks.
Built with advanced XPI ultra-high pressure injection technology, this injector adopts precision wear-resistant micro multi-hole alloy nozzle and fast-response integrated solenoid valve to achieve multi-stage accurate micro fuel injection and micron-level ultra-fine atomization. It maintains steady power output under long-distance full-load transportation and resolves a full set of common engine faults: insufficient power, black exhaust smoke, hard cold startup, rough fluctuating idle speed, high fuel consumption, fuel leakage and ECU cylinder misfire trouble codes.
Multi-layer high-temperature resistant FKM sealing rings and thickened copper pressure washers effectively resist sustained high operating temperature and violent mechanical vibration of highway trucks and construction vehicles.

Each finished injector undergoes full professional bench calibration, covering tests of injection pressure, fuel flow uniformity, spray pattern and electrical signal consistency. Every injector is equipped with exclusive IQA calibration code; professional diagnostic scanner is required to program the code into ECU after installation to balance cylinder power output, stabilize torque and pass official exhaust emission inspection.
We have brand new and remanufactured injectors in stock. Neutral export carton packaging, flexible MOQ and tiered bulk wholesale discounts are supported. Our 12-month global warranty provides reliable after-sales service for worldwide diesel spare parts distributors, truck repair shops and fleet maintenance service yards.
