Abstract
In an internal combustion engine, an amount of spray attaching onto an inner wall surface of an intake pipe is reduced by forming a two-directional spray of highly atomized fuel. The highly atomized two-directional spray can be obtained by a spray forming means constructed by piling a fuel in-plate forming fuel passages, a swirl plate forming fuel passages for adding swirl forces to the fuel, and an injection plate for determining injection directions of the fuel. Further, penetrations of the sprays injected toward two directions are made different from each other.
