Beschreibung
Zusammenfassung:	A system comprises a main housing 502, a first inner housing 512, and a second inner housing 542. The first inner housing has an inlet 508 and an outlet, the outlet being in fluid communication with a volume defined by the main housing. The second inner housing has an inlet and an outlet 552, the inlet being in fluid communication with the volume. The inner housings each have a centreline axis which are parallel and offset to each other. The inlets of the inner housings are both positioned at a first end of the main housing. A diesel particulate filter (DPF) 506 is disposed in the first inner housing, and a selective catalytic reduction catalyst (SCR) 540 is disposed in the second inner housing. The volume defined by the main housing may be a decomposition chamber 520. The DPF may comprise one or more silicon carbide (SiC) filters 510. The SCR may comprise one or more extruded SCR catalysts 546.
