Abstract

Eine Abgasanlage für einen Kolbenmotor umfasst eine Oxidations-Katalysatoreinrichtung und einen nachgeschalteten Partikelfilter. Die Katalysatoreinrichtung umfasst eine Katalysatorstruktur (20) mit einer Vielzahl paralleler und an beiden Enden offener Kanäle (22). Es wird vorgeschlagen, dass die Wände (24) zwischen den Kanälen (22) eine Porosität von mindestens 30 % aufweist.
