Abstract

Das Gehäuse eines Abgaskatalysators mit in seinem Inneren über Blähmatten (2) gelagerten katalytischen Keramikkörpern (1) ist aus einer Trägerschale (3) und einer diese umgebende Isolationsschale (9) aufgebaut, die zwischen sich einen ringförmigen Hohlraum (11) einschließen. Die Isolationsschale (9) ist in den Bereichen, in denen die Keramikkörper (1) angeordnet sind, mit Ventilationsöffnungen (12) versehen, durch welche der Fahrtwindstrom (13) zur Kühlung der Trägerschale (3) in den der Lagerung der Keramikkörper (1) dienenden Bereichen in den ringförmigen Hohlraum (11) eintritt. In den übrigen Bereichen hat der ringförmige Hohlraum (11) eine isolierende Funktion und verhindert eine unerwünschte Abkühlung des Abgases.
