ABSTRACT:
A fuel vaporizer for internal combustion engines is disposed at a suitable position in an intake passage of a carburetor or an intake manifold. The fuel vaporizer comprises a heating cylinder installed in registry with a barrel of the carburetor or a heating plate embedded in a wall of the intake manifold. The heating cylinder or plate includes a base body of electrically and thermally insulative ceramics coated on a surface thereof with a thin film of electrically resistive material such as metal capable of being heated when an electric current flows therethrough, the thin film lying substantially flush with the wall of the intake passage and being electrically connected to a power supply via a switch. When the heating cylinder or plate is heated, it effectively and reliably evaporates fuel in liquid phase flowing down the intake passage into contact with the heated thin film.
