Abstract

Es wird ein Verfahren zur Regeneration eines Partikelfilters vorgeschlagen, bei dem das Filter bei ausgeschalteter Brennkraftmaschine regeneriert werden kann (Schritt 100). Bei stehender Brennkraftmaschine müssen im Abgastrakt keine Abgase erhitzt werden, um die gesamte Filteranordnung auf die für die Regeneration erforderliche Temperatur zu bringen; dies ermöglicht eine energetisch effiziente Durchführung der Regeneration.
