A vaporizer unit has an enclosing casing including a plurality of tubes therein, defining a fuel passage therethrough, including the tubes. The tubes have coiled wire screen therein. An auxiliary carburetor is positioned at the inlet end of the fuel passage, and an outlet passage leads to the main carburetor of the automobile. The casing also defines an exhaust passage therethrough, transversely of the fuel passage, providing heat transfer between the exhaust gases and the tubes. The temperature of the resulting vaporized fuel is sensed for varying the flow of the exhaust gases and thereby controlling the temperature of the vaporized fuel, which is maintained at 250°F. to 260°F. An electric crystal is used for breaking down the heavy ends of the fuel. The rate of flow of air to the main carburetor is varied for correspondingly varying the rate of intake of vaporized fuel from the vaporizer unit. Automatic and manual controls are both utilized selectively, each without interfering with the other.
