ABSTRACT:
A fuel injection valve having an adapter 50 molded from resin and mounted to an extreme end of an injection valve main body 1; a plurality of air/fuel mixing passages 51 formed in the adapter 50 at equal pitches about a first center line drawn axially through the fuel injection valve, having passage centers defined from cross-sectional areas of the air/fuel mixing passages 51 which provide second center lines through each of the passage centers; the second center lines intersect at one point on the first center line, the intersection point being positioned on an upper stream side of the adapter 50, each of the passages 51 being disposed at a same angle of inclination with respect to the first center line; air passages 52, formed in the adapter 50 which communicate with the air/fuel mixing passages 51 to introduce air into the passages 51; a plate 24, disposed between the injection valve main body 1 and the adapter 50; and orifice holes 24a, formed in the plate 24 to confront openings of the plurality of air/fuel mixing passages in order to distribute the fuel from the injection port to the plurality of air/fuel mixing passages 51, wherein the plurality passages 51 are formed having virtual edge portions at the openings thereof which contact each other, without overlapping, at the upstream end surface of the adapter and wherein a cross section of each of the passages 51 is linearly shaped and approximately parallel with a tangential line of an adjacent virtual edge portion forming a partition wall 53 of prescribed thickness between adjacent passages 51.
