Abstract

Ein Abgasreinigungsgerät für einen Verbrennungsmotor (1) besitzt einen Kollektor (40), eine Druckdifferenz-Erfassungsvorrichtung (61), eine auf der Druckdifferenz basierende Schätzvorrichtung (S104), eine Trennwand-Freilegungs-Erfassungsvorrichtung und eine zweite Regenerationsvorrichtung. Der Kollektor (40) fängt in dem Abgas befindliche Abgaspartikel ein. Die Druckdifferenz-Erfassungsvorrichtung (61) erfasst eine Druckdifferenz in dem Kollektor (40). Die auf der Druckdifferenz basierende Schätzvorrichtung schätzt eine Ansammlungsmenge der Abgaspartikel, basierend auf der Druckdifferenz. Die Trennwand-Freilegungs-Erfassungsvorrichtung erfasst einen Trennwand-Freilegungszustand. Die zweite Regenerationsvorrichtung verbrennt die in dem Kollektor (40) gefangenen Abgaspartikel zwangsweise vollständig, wenn die Trennwand-Freilegungs-Erfassungsvorrichtung den Trennwand-Freilegungszustand erfasst.
