Abstract
The present invention relates to a mixing apparatus for introducing and distributing a liquid additive into a gas flow, in particular for an exhaust gas system of an internal combustion engine. The mixing apparatus comprises a gas-guiding section for guiding the gas flow and a metering-in device for introducing the additive into a metering-in region of the gas-guiding section. Furthermore, a heating device for actively heating at least one heating section of the gas-guiding section is provided. The heating section is arranged in the metering-in region and/or downstream of the metering-in region. The gas-guiding section has, in the heating section, at least one elevated portion projecting radially into the gas flow for influencing the flow of the gas flow and thus the preparation of the additive.
