Abstract
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.
