Abstract

Un manchon (24) qui est rempli d'une matière catalytique (10) constituée d'un mélange de nylon générant des ions négatifs et d'un matériau céramique, est raccordé à un conduit de combustible (18) reliant un réservoir de combustible (16) à un moteur thermique (14), de sorte qu'une charge négative soit appliquée au combustible liquide (12) tel que du pétrole destiné à l'alimentation. Ainsi, un catalyseur permettant d'effectuer un traitement de précombustion sur le combustible liquide est placé dans le conduit de combustible reliant le réservoir de combustible au moteur thermique, ceci permettant de réduire la quantité des substances nocives dans les gaz d'échappement émanant du moteur thermique.
