Abstract
Abstract THERE IS DISCLOSED A METHOD OF PROVIDING HIGH OCTANE ANTI-KNOCK GASOLINE WITHOUT UTILIZING LEAD COMPOUNDS, WHICH WHEN UTILIZED IN A TYPICAL AUTOMOTIVE INTERNAL COMBUSTION ENGINE, WILL SIGNIFICANTLY REDUCE THE LEVELS OF OBJECTIONABLE AND, IN SOME CASES, DANGEROUS ATMOSPHEREIC POLLUANTS. ALSO DISCLOSED ARE MIXTURES OF CERTAIN ALCOHOLS, WATER AND GASOLINE HYDROCARBONS WHICH HAVE A SUFFICIENT OCTANE RATING BUT AT THE SAME TIME, EXHIBIT LOWER EMISSION LEVEL. SPECIFICALLY, THE METHOD COMPRISES THE COMBINED USE OF TYPICAL GASOLINE HYDROCARBONS, CERTAIN SPECIFIC ALCOHOLS AND WATER. THE ANTI-POLLUTION FUEL AND METHODS OF UTILIZING THE SAME ARE ALSO DISCLOSED.
