Cummins 307673600 Top-Stop Fuel Injector Assembly

The Cummins 307673600 is a top-stop type fuel injector engineered for the Dongfeng Cummins ISDe and ISD series 4.5-liter inline four-cylinder diesel engines. This component operates within a high-pressure common rail fuel injection system, delivering precise fuel metering and atomization for optimal combustion efficiency and emissions compliance. Constructed with hardened alloy steel nozzle needles and a solenoid actuator rated for 24-volt electrical systems, the injector withstands peak rail pressures up to 1,800 bar. The nozzle features a multi-hole spray pattern calibrated for the specific combustion bowl geometry of the ISDe/ISD platform. It serves as a direct replacement for the original equipment injector installed on Dongfeng commercial vehicles and industrial equipment powered by these engine models.
