ルエンジンのスロットル型燃料噴射ノズル。In a throttle type fuel injection nozzle in which a nozzle hole is provided in a nozzle body and a tip of a needle valve is disposed within the nozzle hole with a predetermined gap, the outer circumferential surface of the tip of the needle valve is aligned with the axis. The nozzle is formed into a parallel straight part and a tapered part whose cross-sectional area gradually decreases above the nozzle body, while the nozzle hole area gradually decreases upward from the tip of the nozzle hole inner peripheral surface of the nozzle body. Formed into a tapered part that becomes smaller and a straight part parallel to the axis above the tapered part, both tapered parts face each other when the diagonal needle valve has a low lift, and both straight parts face each other when the diagonal needle valve has a high lift. A throttle type fuel injection nozzle for a diesel engine, characterized in that it is configured to.
