A vaporization device is provided which is adapted to be mounted in an intake passage between a carburetor and combustion chambers in an internal combustion engine. The device comprises a porous member partially extending into the intake passage to create a pressure difference between the front up-stream side and the back down-stream side of the porous member wherein the porous member has porosity fine enough to substantially restrict the flow of mixture of air and vaporized fuel therethrough.
