When you use our products, you may not know what the basic principle of the fuel injector is? Today I will introduce you to the basic principle of the fuel injector. I hope that it will be better when you use it. For help.
    Before the fuel injection pump starts to supply fuel, the injector needle valve is closed and maintained in this state by a spring. After the fuel injection pump starts its pumping stroke, the high-pressure diesel enters the fuel injection nozzle assembly through the fuel inlet pipe joint, and enters the oil cavity around the pressure cone of the needle valve through the oil passage in the fuel injection nozzle body. When the diesel pressure reaches the set pressure When the oil pressure acts on the pressure-bearing cone of the needle valve, the upward thrust of the needle valve will open the needle valve. Diesel will reach the injection hole from the small oil cavity called the oil sac under the needle valve, and the finely divided oil will be dispensed from these injection holes. The mist sprayed out. When the pump oil pressure drops, the needle valve spring makes the needle valve fall on the valve seat, and the fuel injection process ends.
    The above is the basic principle of the operation of the injector.
