Cummins 4062569 HPI Fuel Injector Assembly

The Cummins 4062569 is a High Pressure Injection (HPI) fuel injector designed for 15.0 liter ISX, QSX15, and X15 series diesel engines. It features solenoid-actuated direct injection technology, delivering precise fuel metering and atomization for optimal combustion efficiency and emissions compliance in heavy-duty applications. The injector body is constructed from high-strength alloy steel to withstand extreme cylinder pressures and thermal cycling inherent in mining and long-haul operations. This assembly replaces OEM part numbers 4010346, 4928260, and 4954434. It is calibrated for Cummins QSX15 Tier 3 and ISX15 engine configurations. Primary fitment includes the MCC400A mining dump truck and Terex mining trucks equipped with QSX15 or ISX15 power units. Each unit undergoes flow testing and calibration verification against OEM specifications to ensure consistent spray pattern and opening pressure.
