Abstract
Die Erfindung betrifft Abgasanlagen mit Katalysatoreinrichtung und einem dieser nachgeschalteten Rußfilter für Verbrennungsmotoren, bei der einer mit Abgas beaufschlagten Katalysatorstrecke (2) mit einem oder mehreren Katalysatoren (21; 22) ein Partikel- bzw. Rußfilter (4) ohne vorgeschalteten Brenner nachgeordnet ist. Am Ausgang des Partikel- bzw. Rußfilters (4) ist bzw. sind ein oder mehrere Schalldämpfer (5) angeschlossen. DOLLAR A Der Erfindung liegt die Aufgabe zugrunde, bei derartigen Abgasanlagen die Funktion des Partikelfilters mit geringem Aufwand zu verbessern. DOLLAR A Erfindungsgemäß wird dies dadurch erreicht, dass zwischen dem Ausgang der Katalysatorstrecke (2) und dem Partikel- bzw. Rußfilter (4) eine Zuführungsanordnung (3) für Zusatzluft (ZL) mündet. DOLLAR A Vorteilhaft kann die Zuführung von Zusatzluft (ZL) eine vom Abgas durchströmte Injektoranordnung (31) sein oder über ein zwischengeschaltetes, gesteuertes Regelventil (8) aus einen Luftbehälter (7) oder von einem Luft fördernden Aggregat erfolgen.
