Abstract

Bei einer insbesondere für Zweitakt-Brennkraftmaschinen (1) bestimmten Auspuffanlage besteht wenigstens der an die Brennkraftmaschine (1) anschließende Teil (2) aus zwei zusammengefügten Blechschalen (3) und enthält einen Kata­ lysator (7). Um eine einfache Herstellungsmöglichkeit zu erreichen, ohne die Gasdynamik zu beeinträchtigen, ist der Katalysator als zwischen den Blechschalen (3) in Strömungs­ richtung verlaufende, katalytisch beschichtete Mittelwand (7) ausgebildet.
