Built for demanding diesel operations, the 2C0273 fuel injector assembly is a new OEM/OEM replacement component for selected 3412 Series engines and related heavy-duty applications. Also referenced as 2C-0273, it is designed for installation in the cylinder head and manufactured from high-strength alloy steel with precision-machined internal components. Its heavy-duty construction and corrosion resistance support reliable fuel delivery in high-load industrial and marine environments.

Within the diesel fuel injection system, high-pressure fuel enters the injector body and the internal needle valve remains closed until the specified pressure is reached. The nozzle then opens, atomizing fuel into fine droplets for delivery to the combustion chamber, before closing to help prevent fuel leakage. This precise metering and uniform spray pattern support controlled fuel quantity, improved combustion efficiency, reduced fuel consumption, lower exhaust emissions, stable performance, and enhanced engine durability. Advanced nozzle design and OEM-level dimensional and performance compatibility help maintain consistent injection characteristics under varying loads.

The 2C0273 is intended for 3412, 3412E, and 3408 engine applications, including industrial diesel, marine propulsion, and generator set engines. Equipment uses listed for this injector include mining trucks, marine engines, generator sets, excavators, industrial power units, oil and gas equipment, and other heavy-duty diesel equipment. Compatibility varies by configuration and should be verified using the engine serial number and arrangement number before ordering.
