Cummins 3084108 Fuel Injector Assembly

The Cummins 3084108 is a PT (Pressure-Time) type fuel injector designed for heavy-duty diesel applications. It utilizes a mechanical actuation principle where fuel metering is controlled by the pressure and time the injector plunger is open, ensuring robust performance in severe operating environments. This injector assembly serves as a direct replacement for Cummins NTA855, NT855, L10, VTA1710, G28, and V28 engine series. It features a multi-hole nozzle configuration optimized for combustion efficiency and emissions compliance applicable to the engine platform. The component is manufactured to OEM specifications for fit, form, and function, supporting reliable cold starts and consistent power output.
