The function of fuel injector

Injector function, injector gasket manufacturers small make up for you to introduce it:

Is diesel spray into a finer particles, and their distribution in the combustion chamber, according to the requirement of the mixture formation and combustion, injection pressure and fuel injector should be range, and suitable spray cone Angle, in addition, the injector in the regulation of stop injection time should be able to quickly cut off the supply of fuel oil, dripping phenomenon does not occur. The fuel injector assembly consists of fuel injector body, fuel injector coupling parts, tight cap, push rod, pressure regulating screw, etc. How the injector works: when the axial force of the high-pressure fuel acting on the nozzle needle valve exceeds the pre-tightening force of the pressure-regulating spring, the needle valve is lifted (opened) and the fuel is sprayed into the combustion chamber through the nozzle orifice. When the oil supply is interrupted, the needle valve of the nozzle, under the action of the pressure-regulating spring, is pressed tightly on the sealing cone of the nozzle body (closed), and the fuel injection stops.
