Engineered for demanding heavy-duty diesel platforms, the 392-0214 Electronic Unit Injector delivers high-precision fuel metering and superior atomization across the entire operating range of 3512B, 3516B, and 3508B industrial engines. The injector is fully interchangeable with OE references 3920214, 20R-1275, 11R-0285, 10R-1290, 0R-8892, 0R-8690, 114-6469, 126-7995, 132-0204, 150-4456, 229-0193, 250-1314 and 386-1766, offering global sourcing flexibility for OEM buyers, aftermarket distributors, and remanufacturing suppliers.

Manufactured from premium hardened steel alloys, the injector body and precision-machined multi-hole nozzle withstand extreme combustion pressures and thermal stress. A corrosion-resistant surface treatment ensures reliable performance in marine, offshore, and mining environments. Each unit is calibrated with the correct trim codes for ECM compatibility, guaranteeing consistent droplet size, optimized spray pattern, and complete combustion. The result is lower fuel consumption, reduced emissions, and prolonged component life during continuous industrial operation on 3500 Series power units.

Typical applications include diesel generator sets for utilities, hospitals and data centers, commercial marine vessels, tugboats, cargo ships, mining trucks, crushers, drilling rigs, fracturing pumps, offshore platforms, heavy excavators, crawler cranes, and locomotive auxiliary power units. Installation requires clean injector bores, new O-rings, proper hold-down clamp torque of approximately 70-90 Nm, and ECU trim code programming. Backed by a 12-month warranty and rigorous quality control, this injector provides dependable OEM-grade replacement performance.
