Pre-cooled aerosol spray fuel/air mixture is discharged through an array of metering tubes which are housed within a heat exchange chamber. Engine coolant is circulated through the heat exchange chamber. As the aerosol fuel/air mixture is drawn from the carburetor through the metering tubes and into the manifold, heat transfer from engine coolant circulating through the heat exchange chamber causes the aerosol mixture in the metering tubes to vaporize. In a preferred embodiment, the temperature rise within the heat exchange chamber is limited by heat transfer to an air circulation tube which is coiled within the heat exchange chamber.

A fuel vaporizer assembly for vaporizing the fuel/air aerosol mixture produced by a carburetor for delivery to the intake manifold of an internal combustion engine, said fuel vaporizer assembly comprising a housing having sidewalls enclosing a heat transfer chamber, inlet and outlet fittings for circulating heat transfer fluid through said heat transfer chamber, flow dividing means received within said 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 said heat transfer chamber, the coiled portion of said air circulation tube being exposed to said heat transfer fluid as it is circulated through the heat exchange chamber, said air circulation tube having 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.
