たことを特徴とする燃料噴射弁。 Fuel is injected inward from an annular fuel injection hole formed by a valve and a valve seat placed inside the valve, and the flow rate is controlled by an air needle from an air injection hole located inside the fuel injection hole. The fuel injection valve is configured to promote atomization of injected fuel by injecting air in which the air has been adjusted, wherein the tip of the air needle is formed into a cylindrical shape, and the tip is inserted into the air nozzle. and a tip of the air needle extends downstream to a position where the injected fuel injected from the fuel injection hole can collide.
