Abstract
A.L'INVENTION CONCERNE UN CONVERTISSEUR CATALYTIQUE DES GAZ D'ECHAPPEMENT D'UN MOTEUR A COMBUSTION INTERNE DESTINE A TRANSFORMER LES PRODUITS NOCIFS DE FACON A LES RENDRE INOFFENSIFS. B.CE CONVERTISSEUR EST FORME D'UN BOITIER CYLINDRIQUE 1 PORTANT A SES EXTREMITES DEUX COUVERCLES CONIQUES 2, UN ENROULEMENT CATALYSEUR 5 ETANT FIXE ENTRE DEUX PLAQUES SUPPORT 3, 3A, 3B ET UN TUBE 4 AMENANT LE GAZ A EPURER. ON PRATIQUE SUR LE TUBE 4, SUR L'ENVELOPPE DE L'ENROULEMENT 7, SUR LES PLAQUES 3, 3A, 3B DES PERFORATIONS APPROPRIEES POUR OBTENIR LES DIRECTIONS VOULUES DE L'ECOULEMENT DU GAZ DANS LE CATALYSEUR. C.CE CONVERTISSEUR PERMET D'OBTENIR DE TRES BONNES ACTIVITES CATALYSANTES AVEC UN ECOULEMENT TRES REGULIER ASSURANT UN BON CONTACT DU GAZ AVEC LE CATALYSEUR.
