Title (EN) DEVICE FOR CATALYTICALLY PURIFYING EXHAUST GASES FROM A COMBUSTION ENGINE
(FR) DISPOSITIF POUR L"EPURATION CATALYTIQUE DES GAZ D"ECHAPPEMENT D"UN MOTEUR A COMBUSTION
Abstract: front page image
(EN)Device for catalytically purifying exhaust gases from a combustion engine, and process for implementing such device A porous catalytist body bears against the inner walls of a casing above a winding of a metal wire netting. The annular space between the catalyst body (1) and the casing (2) is obturated by means of an annular seal made of a non-inflammable ceramic fibre material, so that such fibre material is pressed inside and between the windings of the wire netting (3). Further, the wire netting is wound with a superposed layer of fibre material.
(FR)Dispositif pour l"epuration catalytique des gaz d"echappement d"un moteur a combustion ainsi qu"un procede pour la mise en oeuvre d"un tel dispositif. Un corps catalyseur poreux est appuye contre les parois internes d"un boitier au-dessus d"un enroulement d"un treillis de fils metalliques. L"espace annulaire entre le corps catalyseur (1) et le boitier (2) est obture au moyen d"un point annulaire fait d"un materiau fibreux ceramique ininflammable, de maniere que ce materiau fibreux est comprime a l"interieur et entre les enroulements du treillis (3). De plus, le treillis de fils metalliques est enroule avec une couche de materiau fibreux superposee.
