The present invention relates to an exhaust gas treatment device () and an exhaust system () having such an exhaust gas treatment device (), wherein the exhaust system () has at least one exhaust-gas-conducting exhaust gas feed line (), which is attached to an inlet region () of the exhaust gas treatment device (). Improved mixing of the exhaust gas and a space-saving configuration result if the exhaust gas treatment device () has at least one inlet () which is open towards the inlet region () and if a mixing element () is provided, which connects the inlet region () to a through-flow region () by means of input openings (), wherein at least one first input opening () faces a first side () of the inlet region () and at least one second input opening () faces a second side () of the inlet region ().

Exhaust gas treatment device

A mixing and/or evaporating device () for an exhaust system () of a combustion engine (), in particular of a motor vehicle, includes a support body (), which encloses a flat cross section through which a flow can flow running transversely to the axial direction () of the device () in the circumferential direction (). The support body () comprises two long side walls () located opposite each other and two short side walls () located opposite each other, wherein the short side walls () each connect the two long side walls () with each other. At least on one long side wall () at least on one axial end (), a plurality of guide blades () is arranged. The guide blades () stand away in a direction of the other long side wall () and are angled relative to the axial direction ().

Mixing and/or evaporating device

A mixing and/or evaporating device () for an exhaust system () of a combustion engine (), in particular of a motor vehicle, includes a support body which encloses a cross section of the device () through which a flow can flow and which runs transversely to the axial direction () of the device () in the circumferential direction. The support body () has at least one guide blade () which extends away transversely to the axial direction (). An improved efficiency is obtained with the guide blade () having a roof-shaped profile (), including two guide surfaces () that are interconnected via a ridge () or apex.

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.

Device for introducing a liquid into a gas flow

The present invention relates to a mixing element and an exhaust system of an internal combustion engine. The mixing element has two inlet openings and two outlet openings, wherein each inlet opening communicates with both outlet openings.
