Abstract

Convertisseur catalytique du genre comportant une calandre extérieure et un corps catalyseur intérieur. Un manchon 5 en matériau d'isolation thermique contenant de la fibre est interposé sous compression radiale entre le corps catalyseur 1 et la calandre 3. Ce manchon peut être, au moins en partie, en fibres inorganiques polycristallines et présenter une couture longitudinale ouverte 6. Il réduit la transmission de chaleur du corps catalyseur 1 à la calandre et, étant monté sous compression, n'a pas tendance à se séparer de la calandre ni du corps 1 sous l'effet de vibrations. Application à l'épuration de gaz d'échappement de moteurs à explosion.
