Abstract
In the device provided, air/fuel mixture for an internal combustion engine passes through a conventional carburetor where vaporized fuel and aspirated liquid fuel droplets are mixed witth the air. The device comprises a conduit for conveying the carbureted mixture from the carburetor to an intake manifold. The conduit has an upper opening and a lower opening. A rotatable turbulence producing means, such as a freely rotatable impeller, is disposed in the conduit near the lower opening. The rotatable means rotates about a vertical axis by passage of the carbureted air/fuel mixture therethrough and turbulence of the mixture is produced. Liquid fuel droplets are engaged by a collector and vaporizing means which is disposed in the conduit near the upper opening and above the rotatable means. The collector and vaporizing means has a substantially enclosed central portion disposed axially above the vertical axis of the rotatable and outer portions slopingly connected to and disposed above the central portion. The outer portions have openings in at least the uppermost parts thereof for receiving and collecting aspirated liquid fuel droplets. A fuel droplet discharge opening is in the centr…
