ABSTRACT:
Apparatus for reduction of pollutant emissions by internal combustion engines includes a tapered, coaxial multiconical structure used as a gas separator. The gas separator is used to provide oxygen enriched air to an engine, thus providing a reduction in the amount of nitrogen provided thereto. The resulting exhaust gas includes fewer oxides of nitrogen, reduced quantities of hydrocarbons, and decreased percentages of carbon monoxide. Air is directed through the structure, entering at a wide mouth thereof. A fan may be provided for directing the air through the structure. The air exiting at the central portion of the narrow end of the structure, which has an increased ratio of oxygen to nitrogen, is directed by a conduit to the engine inlet. The structure is inexpensive, and easily mounted on existing engines, thus providing a retrofitting device for conforming older cars to current pollution standards.
