Abstract
(DE)
Die Erfindung betrifft einen Katalysator zur Nachbehandlung von Abgasen eines Verbrennungsmotors, mit zumindest einem Katalysator und zumindest einer elektrisch beheizbaren Heizscheibe, wobei der Katalysator und die Heizscheibe jeweils durch einen Wabenkörper mit einer Mehrzahl entlang einer Hauptdurchströmungsrichtung durchströmbaren Strömungskanälen gebildet sind, wobei die mechanische Verbindung zwischen dem Katalysator und der Heizscheibe durch zumindest einen Stützstift (1, 7, 10) gebildet ist, wobei der Stützstift (1, 7, 10) eine innenliegende Seele (2, 8) aufweist und der Stützstift (1, 7, 10) an beiden Endbereichen jeweils eine Verdickung (3) aufweist, wobei die Seele (2, 8) durch ein keramisches Material gebildet ist und die Verdickung (3) durch ein Keramik-Metallgemisch gebildet ist.
(EN)
The invention relates to a catalytic converter for the aftertreatment of exhaust gases of an internal combustion engine, having at least one catalytic converter and having at least one electrically heatable heating disk, wherein the catalytic converter and the heating disk are each formed by a honeycomb body with a multiplicity of flow channels through which flow can pass along a main throughflow direction, wherein the mechanical connection between the catalytic converter and the heating disk is formed by at least one support pin (1, 7, 10), wherein the support pin (1, 7, 10) has an internally situated core (2, 8) and the support pin (1, 7, 10) has a thickening (3) at each of the two end regions, wherein the core (2, 8) is formed by a ceramic material and the thickening (3) is formed by a ceramic-metal mixture.

L'invention concerne un convertisseur catalytique destiné au post-traitement des gaz d'échappement d'un moteur à combustion interne, comprenant au moins un convertisseur catalytique et au moins un disque chauffant pouvant être chauffé électriquement. Le convertisseur catalytique et le disque chauffant sont formés chacun par un corps en nid d'abeilles avec une multiplicité de canaux d'écoulement à travers lesquels un écoulement peut passer le long d'une direction d'écoulement principale. La liaison mécanique entre le convertisseur catalytique et le disque chauffant est formée par au moins une broche de support (1, 7, 10) comprenant un cœur (2, 8) situé à l'intérieur et présentant un épaississement (3) au niveau de chacune des deux zones d'extrémité, le noyau (2, 8) étant formé par un matériau céramique et l'épaississement (3) étant formé par un mélange céramique-métal.
