An exhaust system for a v-configured transverse-mounted internal combustion engine includes a first passage for the first, front manifold exhaust gas stream having a adsorber structure disposed therein and a second passage for the second exhaust gas stream having an catalyst structure disposed therein. The catalyst and the adsorber comprise a single honeycomb adsorber-catalyst structure having a plurality of partition walls extending along an axial direction of the honeycomb structure. The partition walls form at least two portions including a catalyst portion having a catalyst layer provided thereon and an adsorber portion having a adsorber layer supported thereon. Specifically, the portions are separate from each other in a cross-section extending perpendicular to the aforementioned axial direction. The system further includes burn-off catalyst disposed downstream adsorber-catalyst structure. |
