The working principle of automobile fuel injection nozzle is to generate suction by energizing the electromagnetic coil, so that the needle valve is lifted and the spray hole is opened. Fuel is sprayed out at a high speed through the annular gap between the shaft needle and the spray hole of the needle valve head, forming a fog, which is conducive to full combustion. The nozzle itself is a normally closed valve that remains closed in the absence of an input control signal

Precise control of oil supply : the oil nozzle can control the amount of oil supply very precisely to ensure that the engine can have a suitable air-fuel ratio under any circumstances, so as to make the engine run smoothly, exhaust gas emission in line with environmental protection regulations, plays a key role in the engine power
prolongs service life : Regular cleaning of the fuel nozzle can extend its service life. It is recommended to clean the nozzle every 20,000 to 30,000 kilometers to avoid long-term idling, and running at a proper speed also helps to keep the nozzle working normally
