Abstract

a. Dispositif pour l'épuration catalytique de gaz d'échappement, en particulier des gaz des moteurs à combustion interne des véhicules automobiles. b. Dispositif caractérisé en ce qu'il comprend un ou plusieurs tubes métalliques, établis ou équipés de façon à perturber l'écoulement et/ou en modifier le sens, qui produit une élévation de la pression dynamique de 0,3 à 2 500 mm de hauteur de colonne d'eau par rapport à un tube ou système tubulaire correspondant, non équipé de façon à perturber l'écoulement et/ou sa direction, cette pression dynamique étant mesurée avec une vitesse d'écoulement de l'air de 12 m/sec., à la température ambiante, ce tube étant revêtu totalement ou partiellement d'une masse catalytique. c. Dispositif applicable à des moteurs à combustion interne d'automobiles.
