Abstract
An injection section () of an exhaust system for an internal combustion engine, with a channel () for guiding an exhaust gas flow (), with an injection port (), laterally on the channel to which a liquid or gas injector () can be connected, and with an injection chamber (), formed in the channel in the area of the injector port. The chamber is defined by a perforated, first flow through partition (), arranged in the channel upstream of the injector port relative to the exhaust gas flow and, and by a perforated, second flow through partition, arranged in the channel downstream of the injector port relative to the exhaust gas flow. Improved mixing and/or evaporation is achieved with the perforation portion of the first partition generating at least two partial exhaust gas flows (), which form two mutually opposite flow swirls ().
