Abstract

DANS CE CONVERTISSEUR CATALYTIQUE EST PREVU EN AMONT DU CATALYSEUR D'OXYDATION 12 UN TUBE D'INJECTION D'AIR 80 QUI S'ETEND EN TRAVERS DU PASSAGE DES GAZ D'ECHAPPEMENT. CE TUBE PRESENTE TROIS RANGEES RECTILIGNES DE TROUS 94 ET 94, LES TROUS 94 FAISANT FACE VERS L'AMONT TANDIS QUE LES TROUS 94 DEBOUCHENT DANS LES DIRECTIONS OPPOSEES ET TRANSVERSALES AU FLUX DE GAZ D'ECHAPPEMENT. LES TROUS DE CHAQUE RANGEE SONT REGULIEREMENT REPARTIS SUR LA LONGUEUR DU TUBE ET LEURS DIMENSIONS DECROISSENT VERS L'EXTREMITE FERMEE 92 DU TUBE DE MANIERE A DEBITER DES QUANTITES D'AIR A PEU PRES UNIFORMES. LES TROUS 94 DEBITENT ENVIRON 80 A 90 DU DEBIT TOTAL D'AIR.
