Engineered for the demands of continuous heavy-duty service, the 3411767T high-pressure diesel fuel injector delivers precise fuel metering for the Cummins N14 14.0L engine family, including N14 Celect, Celect Plus, turbo variants, and medium duty configurations. Manufactured from hardened alloy steel with an anti-corrosive finish, each unit is CNC machined and micro-finished to maintain consistent injection timing across long duty cycles, with a service weight of approximately 1.1–1.3 kg.

Multi-hole nozzle technology enhances fuel atomization to reduce smoke and support cleaner combustion, while the injector operates at pressures up to ~2200 bar within a thermal range of -40°C to +250°C. Surface treatments provide wear and corrosion resistance, and every injector is bench calibrated for flow, pressure, and leak performance. Built to meet or exceed Cummins standard tolerances, the 3411767T offers an estimated service life exceeding 150,000 miles and carries a 12–24 month warranty depending on supplier.
