摘要： 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.

摘要： Atomization and vaporization of spray in a fuel supply system is promoted at the time of cold startup and the amount of fuel depositing on the inner wall of the intake manifold is reduced, thereby ensuring improved startability of an internal combustion engine of a car, reduced fuel costs and improved purification of exhaust gas. A very fine groove is formed on a heat transfer surface in a fuel vaporization promoting apparatus, wherein this groove is shaped in such a way that fuel is dispersed by the surface tension of the heat transfer surface and the fuel. This configuration ensures uniform dispersion of fuel on the heat transfer surface and effective promotion of vaporization.
