ABSTRACT:
In an injection hole plate of a fuel injection apparatus, a second-side hole section of each injection hole extends from a downstream end of a base wall of the injection hole plate and is communicated with first-side hole sections, which extends from an upstream end of the wall of the injection hole plate to an axially intermediate point of the wall. The first-side hole sections may discharge fuel into the second-side hole section in a manner that forms a swirl fuel flow in the second-side hole section. The injection hole plate may includes a collision portion, in which fuel flows supplied from the first-side hole sections collide with one another.
