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.

The present invention relates to a device for introducing a liquid into a gas flow, more preferably for an exhaust system of an internal combustion engine. The device includes a chamber, an injection device and a channel. The channel with a circumferential region of an inlet section protrudes into the chamber and there on an inner side facing the gas flow has a surface. Said surface is arranged offset to the inside with respect to a channel profile. The proposed design results in improved evaporation of the liquid introduced into the gas flow.
