Abstract

La presente invención se refiere a montaje de un convertidor catalítico monolítico caracterizado por un dispositivo para tratamiento de gases de escape procedentes de un motor de combustión interna, que comprende: a) un alojamiento que tiene una entrada en un extremo y una salida en su otro extremo opuesto, a través del cual circulan los gases de escape; b) un monolito de cerámica frangible montado elásticamente dentro de dicho alojamiento, teniendo dicho monolito una superficie exterior y una cara extrema de entrada en un extremo, en comunicación con dicha entrada del citado alojamiento y una cara extrema de salida en su extremo opuesto, en comunicación con dicha salida del mencionado alojamiento; c) una capa de fibras cerámicas en contacto con al menos una parte de dicha superficie exterior del mencionado monolito y que la recubre; y d) una capa intumescente dispuesta entre dicho alojamiento y dicha capa de fibras cerámicas.
