Abstract

Selon l'invention, le combustible gazeux (1) ou un mélange combustible-air, lorsqu'il est injecté, est traité avec un champ de décharge (2) de haute tension alternative électrique de townsend (silencieuse) et subit un traitement catalytique (8) qui augmente la teneur en radicaux hydrocarbonés et atomes d'hydrogène pendant la combustion. Les additifs contenant de l'oxygène (4) sont ajoutés avant le traitement du combustible gazeux et/ou du mélange combustible-air pour accroître la teneur en radicaux contenant de l'oxygène pendant la combustion. En outre, un type spécial de décharge électrique -décharge de townsend (silencieuse) - est fourni aux électrodes qui sont enrobées de diélectrique et qui ont, posés sur elles, des catalyseurs. De plus, la décharge (silencieuse) de townsend possède le potentiel alternatif, tandis que la tension de 2 à 20 kilovolts est maintenue de façon à produire des radicaux hydrocarbonés avec le champ de haute tension alternatif électrique. De plus, les radicaux hydrocarbonés sont produits par la décharge gazeuse de fréquence accrue et potentiel alternatif.
