Title: Fuel catalyst apparatus for exhaust gas purification

Abstract: The present invention relates to a catalyst apparatus for exhaust gas purification which decreases toxic substances included in the exhaust gas of internal combustion engines, by interposing a catalyst in a fuel pipe connecting a fuel tank and the internal combustion engine and charging the fuel with negative electric charges thereby improving the combustion efficiency, to be used in the field of exhaust gas purification for internal combustion engines of automobiles, watercraft and aircraft. The catalyst device 20 or 30 is installed for giving negative electric charges to a liquid petroleum fuel 18 which is sent through a fuel pipe 12 running from a fuel tank 11 to the internal combustion engine 14.
