Abstract

A device for exhaust-gas treatment near an engine includes an annular structure and a guide structure disposed in an exhaust line. An inner wall forms an inner flow passage and an outer flow passage in the annular structure. The inner wall and the guide structure form a gap in such a way that only a limited secondary flow of the exhaust gas is conducted through the inner flow passage. A motor vehicle having the device is also provided.
