Diesel Common Rail Fuel Injector 0445120238 For  Dodge Ram Cummins 5.9L

 The fuel injector assembly is composed of injector body, coupling parts, push rod, spring and pressure regulating bolt. There is an oil passage on one side of the nozzle body, which leads into the cavity at the lower end of the needle valve. Normally, the needle valve is closed under the action of spring. When the pressure oil enters, the needle valve rises against the spring’s elastic force under the push of the pressure oil, and the fuel is sprayed out from the oil hole at the tip of the needle valve. Due to the special damping effect, the fuel will be foggy.
