Abstract

Die Erfindung betrifft eine Abgasanlage für Kraftfahrzeuge mit einem Wärmetauscher folgender Ausgestaltung:
  • er ist aus einem Außen- und einem Innenrohr (1,2) gebildet,
  • zwischen den beiden Rohren ist ein Radialspalt (3) vorhanden, der an seinem gegen die Strömungsrichtung (4) weisenden vorderen Ende (7) eine dem Eintritt von Abgas verhindernde Abdichtung aufweist,
  • der sich an die Abdichtung anschließenden Bereich des Innenrohres (2) ist von Bypass-Öffnungen (9) durchbrochen, und
das in Strömungsrichtung weisende, eine Ausströmöffnung (23) umfassende hintere Ende (8) des Innenrohres ist nach Art einer Düse verengt, wobei die Ausströmöffnung (23) mit dem Radialspalt (3) verbunden ist.
