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. In particular for two-stroke internal combustion engines (1) certain exhaust system there is at least that to the Internal combustion engine (1) connecting part (2) from two assembled sheet metal shells (3) and contains a kata analyzer (7). To make it easy to manufacture achieve without affecting the gas dynamics is the Catalyst as flowing between the metal shells (3) directional, catalytically coated middle wall (7) trained.
