Fuel vaporization promoting device for an internal combustion engine
 A fuel vaporization promoting device comprises a heater vessel arranged in the collecting portion of the intake manifold of an engine. The heater vessel contains therein at least one PTC element and is shaped in the form of a flat plate. The heater element is spaced above the bottom wall of the collecting portion by a support member having a small cross-sectional area so that an air gap is formed between the lower face of the heater vessel and the bottom wall of the collecting portion. The heater vessel is actuated after the engine is operating under its own power and is turned off when the warm-up of the engine is completed.
