Talbert, W L

This patent describes a low Reid Vapor Pressure liquid gasoline for use in a standard carbureted internal combustion engine. It comprises: a priming agent and a hydrocarbon mixture having an intermediate carbon range relative to C{sub 4}-C{sub 12} fuel; the intermediate carbon range consisting essentially of C{sub 6}-C{sub 10} hydrocarbons with C{sub 9} and C{sub 10} paraffinic hydrocarbons being present in the mixture; the gasoline having a boiling point range of 121{degrees} F.-345{degrees} F. at 1 atmosphere pressure; and the priming agent consisting of a hydrocarbon selected from the priming agent consisting of C{sub 4} and C{sub 5} hydrocarbons and mixtures thereof and the priming agent being present in a minimum effective amount for raising the front end volatility of the gasoline to a minimum level for cold engine starting with the minimum effective amount being less than that required for C{sub 4}-C{sub 12} gasoline.
