Abstract
Description
- Fig. 1
- einen Längsschnitt durch eine erfindungsgemäße Abgasanlage in einem Bereich, in dem ein Abgasrohr an eine Katalysator- oder Partikelfiltereinheit angeschlossen ist,
- Fig. 2
- eine Darstellung wie in Fig. 1, jedoch bei einer anderen Ausführungsform.
Claims (5)
- Abgasanlage für eine Brennkraftmaschine, insbesondere eines Kraftfahrzeugs,mit einem Abgasrohr (2), das an eine Katalysator- oder Partikelfiltereinheit (3) angeschlossen ist, die in einem Gehäuse (4) wenigstens einen Monolithen (5) oder wenigstens einen Partikelfilter (5) enthält, dessen Querschnitt (9) größer ist als ein Querschnitt (11) des Abgasrohrs (2) an einem Mündungsende (12) des Abgasrohrs (2),wobei die Katalysator- oder Partikelfiltereinheit (3) einen Trichter (6) aufweist, an dem das Abgasrohr (2) angeschlossen ist,wobei der Trichter (6) an seinem an das Abgasrohr (2) angeschlossenem ersten Ende (7) eine erste Längsmittellage (15) und an seinem, dem Monolithen (5) oder dem Partikelfilter (5) zugewandten zweiten Ende (8) eine zweite Längsmittelachse (16) aufweist, die gegenüber der ersten Längsmittelachse (15) geneigt ist,wobei das Abgasrohr (2) mit seinem Mündungsende (12) durch das erste Trichterende (7) hindurch in ein Trichterinneres (17) freistehend hineinragt,wobei das Abgasrohr (2)an seinem Mündungsende (12) so geformt und dimensioniert ist, dass es in das erste Trichterende (7) einsteckbar ist.
- Abgasanlage nach Anspruch 1,
dadurch gekennzeichnet, dass das Abgasrohr (2) im Trichterinneren (17) eine geradlinig verlaufende Längsmittellinie (14) aufweist. - Abgasanlage nach Anspruch 1,
dadurch gekennzeichnet, dass das Abgasrohr (2) im Trichterinneren (17) ein gebogen oder gekrümmt oder abgewinkelt verlaufende Längsmittellinie (14) aufweist. - Abgasanlage nach einem der Ansprüche 1 bis 3,
dadurch gekennzeichnet, dass das Mündungsende (12) in einer Ebene (21) liegt, deren Normale gegenüber der Längsmittellinie (14) des Abgasrohrs (2) im Mündungsende (12) geneigt ist. - Abgasanlage nach einem der Ansprüche 1 bis 4,
dadurch gekennzeichnet, dass das Mündungsende (12) in einer Ebene (21) liegt, deren Normale im wesentlichen parallel zur Längsmittelachse (13) des Monolithen (5) oder des Partikelfilters (5) verläuft.
