Abstract

Die Erfindung betrifft ein Abgassystem (1) für eine Brennkraftmaschine (2), insbesondere für eine Dieselbrennkraftmaschine, mit einem Abgasstrang (3), in welchem zumindest eine Abgasnachbehandlungseinrichtung angeordnet ist, mit zumindest einer stromabwärts eines ersten Oxidationskatalysators (4) angeordneten Denox-Einheit. Um die NOx-Emissionen zu reduzieren ist vorgesehen, dass stromaufwärts der Denox-Einheit ein zweiter Oxidationskatalysator (5) angeordnet ist.
