Abstract:
1. A device for introducing a liquid into a gas flow, for an exhaust system of an internal combustion engine comprising: a chamber in which in operation of the device, a gas flow flows in a main flow direction; an injection device arranged on the chamber, which in operation, injects a liquid into the chamber, with a main injection direction which is inclined relative to the main flow direction; a channel connected to the chamber opposite the injection device which channel in operation discharges the gas flow from the chamber in a channel longitudinal direction which is inclined relative to the main flow direction; wherein the channel comprises an inlet section which on the face end is beveled relative to the channel longitudinal direction so that a first circumferential region of the inlet section located downstream with regard to the main flow direction in the channel longitudinal direction protrudes deeper into the chamber than a second circumferential region of the inlet section located upstream with respect to the main flow direction; and wherein the channel in the inlet section on an inner side of the first circumferential region facing the gas flow comprises a surface which comprises at least one region offset to the inside opposite a profile of the channel which the channel has in a channel section adjoining the inlet section.
