Alcohol and water are mixed as liquids in a volume ratio of water to alcohol in the range 0.3-1.0 to 1. The liquid mixture is heated in heat exchanging relation with the exhaust conduit of a gasoline operated internal combustion engine, to convert the mixture to a gaseous state which is then combined with a mixture of gasoline and air for introduction into the engine. The water-alcohol mixture is 3-14 vol. % of the gasoline.
