Abstract

Abstract A liquid for vaporizing and subsequent introduction, downstream from the carburetor, into the fuel stream of a gasoline-fired internal combustion engine, the liquid comprising water and a concentrate mixed with said water, the concentrate including methanol and nitro-methane. The concentrate may also include a suitable blender or blenders such as acetone and nitro-benzene. The acetone is effective to prevent separation of the nitromethane and methanol.
