Cummins 5347134 Fuel Injector Assembly

The Cummins 5347134 is a common rail diesel fuel injector designed for the ISF2.8 and ISF3.8 engine platforms. It utilizes Bosch solenoid valve actuation technology to deliver precise fuel metering and multi-event injection strategies required for modern emissions compliance. The injector body is manufactured from high-strength alloy steel to withstand peak rail pressures up to 1800 bar. Internal components include a precision-machined control valve, nozzle needle, and stainless steel nozzle tip with micro-drilled orifices for optimized spray pattern and combustion efficiency. This assembly serves as a direct replacement for Cummins OEM part number 5589195 and Bosch part number 0445110808. It is calibrated to factory flow specifications to ensure correct idle stability, power output, and exhaust aftertreatment compatibility. Applications span light-duty commercial vehicles including Foton Tunland, Foton Auman series, JAC light trucks, and GAZ light trucks equipped with the Cummins ISF engine family.
