Abstract
This liquid fuel vaporizing apparatus is so designed that liquid fuel is vaporized by a heating plug disposed in a tubular body when the temperature in a combustion chamber is low while it is vaporized by a radiant heat of the combustion chamber received by heat-receiving fins provided in the outer-peripheral part of the tubular body when the temperature in the combustion chamber is high. Particularly, an open-cellular member having intercommunication porosity which has numerous intercommunicating pores being excellent in heat conducting properties is disposed in a fuel passage in the tubular body, and the heat transfer area of said member is increased to make uniform the state of reception of heat from the heat-receiving fins. The liquid fuel is turned into a thin films by intercommunicating pores in the tubular body to improve a vaporizable property and thereby to prevent the bumping of oil droplets in the tubular body, thus making the vaporized fuel jetted excellently at all times from a fuel injection pipe.
