Abstract

Abstract A fuel for internal combustion engines is composed of a mixture of alcohol and gasoline in which the alcohol content is 70 to 85 volume % and the gasoline consists essentially of aromatic, alkanic and cycloalkanic hydrocarbons and, optionally, olefinic hydrocarbons the hydrocarbons having 3-11 carbon atoms, the aromatic hydrocarbons constituting 35 to 45 weight % of the gasoline and the aromatic and any olefinic hydrocarbons constituting cumulatively 35 to 60 weight % of the gasoline.
