A device for use in association with a carburetor (C) of the type used for supplying fuel at the intake manifold (M) of a gasoline internal combustion engine has an annular chamber (17) at the exit port of the carburetor (C), adapted to collect uncarbureted raw gasoline particles or globules for drainage through an external vaporizing system under the influence of the vacuum created at the intake manifold (M) during operation of the engine for reintroduction as vaporized fuel at the intake manifold (M), thereby converting raw gasoline, otherwise wastefully fed to the engine, into efficiently combustible fuel. The usual throttle butterfly valve (43) of the carburetor (C) is modified to provide a collection chamber (48) for raw gasoline which is continuously withdrawn through an axial passageway (45) in the butterfly valve pivotal axle (44) for drainage through the external vaporizing system. |
