A spray angle of 30.degree. or less is obtainable, and a rate of change in fuel flow between an air-injection time and a non-air-injection time can be reduced. Further, the relation between the diameter D.sub.1 of the upstream portion and the diameter D.sub.2 of the downstream portion is determined to be D.sub.1
