Abstract

Rußfilteranlage im Abgastrakt einer Diesel-Brennkraftmaschine umfaßt wenigstens zwei -parallel geschaltete Rußfilter (5, 6). Zur Regenerie­ rung ist eine Regenerierungseinrichtung mit wenigstens einem Brenner (10) vorgesehen und den Rußfiltern (5, 6) der Rußfilteranlage sind Steuerklappen (8) vorgeschaltet, mittels denen der jeweils zu re­ generierende Rußfilter von der Durchströmung der Abgase im Abgastrakt abgekoppelt wird. Der Brenner (10), der für die Regenerie­ rung der Rußfilter heiße Verbrennungsgase liefert, wird mit Abgas aus der Abgasanlage betrieben, das als Sauerstoffträger dient und er ist stromab der Steuerklappe (8) angeordnet. Gemäß einer ersten bevorzugten Auslegungsform ist ein gemeinsamer Brenner (10) für alle zu regenerierenden Rußfilter vorgesehen und dieser liegt nicht direkt in den Abgas führenden Leitungen der Abgasanlage. Vorzugsweise wird er mit Abgas über gesonderte Abgaszufuhrleitungen (11) versorgt. Alternativ können jeder Zweig­ leitung (3, 4), in der der jeweilige Rußfilter (5, 6) liegt, ein gesonder­ ter Brenner zugeordnet werden, der direkt im Rußfilter im Leitungsabschnitt vorgeschaltet sein kann. Ein solcher Brenner kann direkt durch die an den Steuerklappen austretende Leck­ menge des Abgases versorgt werden. Alternativ können die Brenner, die dem jeweiligen Leitungszweig nur mit den jewei­ ligen Rußfiltern zugeordnet sind auch in einer von diesen Leitungsabschnitten abzweigenden Zweigleitung angeordnet sein und die Brenner werden dann mit einer gesonderten Abgas­ zufuhrleitung versorgt. Soot filter system in the exhaust system a diesel engine includes at least two soot filters connected in parallel (5, 6). For regeneration tion is a regeneration device with at least one burner (10) provided and the soot filters (5, 6) of the soot filter system Control flaps (8) upstream, by means of which to the right Generating soot filter from the flow of exhaust gases in the Exhaust tract is uncoupled. The Brenner (10), for regeneration tion of the soot filter provides hot combustion gases Exhaust gas from the exhaust system operated as an oxygen carrier serves and it is arranged downstream of the control valve (8). According to A first preferred embodiment is a common one Burner (10) provided for all soot filters to be regenerated and this is not directly in the exhaust gas pipes the exhaust system. It is preferably separated with exhaust gas Exhaust gas supply lines (11) supplied. Alternatively, any branch line (3, 4) in which the respective Soot filter (5, 6) is a separate one ter burner can be assigned, which directly in the soot filter in Line section can be connected upstream. Such a burner can directly through the leak emerging from the control flaps amount of exhaust gas are supplied. Alternatively, the Burners that only match the respective line branch with the respective soot filters are also assigned in one of these Line sections branching branch line arranged and the burner will then be using a separate exhaust supply line supplied.
