Built to sustain the demanding operating profiles of Cummins M11 platform diesel engines, the 3411756 Electronic Unit Injector is a precision-engineered heavy-duty fuel injection component designed for CELECT and CELECT Plus systems. This ECM-controlled, solenoid-actuated injector delivers precise fuel metering, optimized spray atomization, and controlled combustion efficiency, supporting reduced exhaust emissions and long-term operational reliability under severe duty cycles across the 10.8L engine platform.

Engineered to OEM manufacturing standards, the 3411756 operates in coordination with the engine control module, which analyzes engine speed, load demand, intake air temperature, coolant temperature, throttle position, boost pressure, and fuel demand. As the internal control valve activates, fuel pressure rises, the nozzle needle lifts, and atomized fuel enters the combustion chamber. Verified cross references include 3411756RX, 3411756PX, EX631756, 209981EX, 209981X, DT3411756R, CK3411756RX, MD0328R, 3609922, and 3083849, ensuring accurate fitment.

This injector serves heavy duty trucks, construction and mining equipment, marine vessels, generator sets, and industrial power systems. For maximum service life, use OEM-grade fuel filters and clean diesel fuel, avoid water contamination, monitor fuel pressure, perform electronic diagnostics, inspect wiring harnesses regularly, and replace damaged seals immediately.
