Abstract
A fuel evaporator comprises a metal member composed of a pipe portion and a flange portion, a heating element made of PTC ceramic, which is closely adhered to the metal member and an electric connector for electrically connecting the heating element and an electric power source. The metal member is supported by an insulating member which is interposed between an air-fuel passage and an intake manifold. The fuel film flow flowing downwards along the wall of the air-fuel passage is received by the flange portion of the metal member and is heated by the heat transmitted from the heating element. Consequently, unvaporized fuel is effectively evaporated.
