ことを特徴とする燃料噴射ノズル。 In a fuel injection nozzle in which a needle is slidably housed in a nozzle body, a plurality of main injection holes are arranged radially around the outer periphery of the tip of the nozzle body, a through hole is opened at the tip of the nozzle body, and a through hole is opened at the tip of the needle. A throttle part that always opens an annular sub-nozzle hole toward the outer periphery is provided between the main and sub-nozzle holes, which inject fuel by lifting the needle. A fuel injection nozzle characterized in that conical sprays from the nozzle holes are set so as to partially overlap.
