Keller, R W

A fuel vaporizer assembly is described for vaporizing the fuel/air aerosol mixture produced by a carburetor for delivery to the intake manifold of an internal combustion engine. The fuel vaporizer assembly consists of a housing having sidewalls enclosing a heat transfer chamber, inlet and outlet fittings for circulating heat transfer fluid through the heat transfer chamber, flow dividing means received within the heat transfer chamber for dividing the fuel/air mixture produced by the carburetor into multiple fluid flow streams for delivery into the intake manifold, and an air circulation tube coiled within the heat transfer chamber, the coiled portion of the air circulation tube being exposed to the heat transfer fluid as it is circulated through the heat exchange chamber. The air circulation tube has a first open end portion adapted to receive ambient air flow and having a second open end portion for venting the ambient cooling air out of the air circulation tube and into the surrounding environment.
