ABSTRACT:
An internal combustion engine carburetor is provided with means for introducing two separate types of liquid into the engine, one of the liquids being gasoline and the other a non-gasoline liquid, such as methyl alcohol, tertiary butyl alcohol, or other alcohols. The carburetor maintains the two liquids separate prior to their introduction into the Venturi to avoid problems normally incurred in blending other liquids with gasoline in liquid form and is constructed to prevent introduction of the non-gasoline liquid during normal idling and starting conditions and to introduce it in metered quantities during normal operation. To ensure vaporization of the two liquids in the primary Venturi, hot air at a temperature at least as high as the end point of the gasoline is introduced directly into the primary Venturi.
