Cummins 4062569 Fuel Injector Assembly

The Cummins 4062569 is a high-pressure common rail fuel injector designed for 15.0 liter displacement diesel engines utilizing HPI (High Pressure Injection) and XPI (Extreme Pressure Injection) fuel systems. It features electronic solenoid actuation for precise fuel delivery timing and quantity control, supporting EPA Tier 4 Final and Euro Stage V emissions standards with integrated DPF, SCR, and EGR aftertreatment compatibility. Unit weight is 2.2 kg with lightweight alloy construction to reduce reciprocating mass. The injector assembly includes the nozzle, solenoid valve, and control valve group calibrated to Cummins factory specifications. OEM cross-references include part numbers 4010346 and superseded variants 4062569RX, 4062569PX, 4062569NX. Remanufactured units typically carry a 6 to 12 month warranty with core charge requirements. Primary applications span heavy-duty on-highway tractors, off-highway construction machinery, mining haul trucks, and marine propulsion. Verified fitment includes platforms powered by ISX15, QSX15, and X15 engine series across OEMs such as Terex mining trucks, Komatsu and Shantui excavators, and various vocational trucks. Professional installation and fuel system contamination inspection are required prior to commissioning.
