Fuel injection nozzle

Abstract

A fuel injection nozzle of the present disclosure is a multi-hole type fuel injection nozzle where a plurality of injection holes are arranged along a circumferential direction about an axis of a nozzle body, and inject fuel radially outward from the axis of the nozzle body. Among two of the plurality of injection holes that are mutually adjacent along the circumferential direction, one injection hole has a larger spray angle and a shorter spray distance as compared to an other injection hole, and the other injection hole has a smaller spray angle and a longer spray distance as compared to the one injection hole. By arranging these injection holes alternately along the circumferential direction, a required inter-spray distance may be maintained and, at the same time, a space utilization ratio may be improved.
