Abstract
An exhaust gas duct system for an internal combustion engine includes an upstream, first exhaust gas pipe area (), a downstream, second exhaust gas pipe area () adjoining the first exhaust gas pipe area () in a transition area () in an exhaust gas flow direction (G), and a liquid drain channel area () in the transition area. The drain channel area is open from the exhaust gas flow volume () in the first exhaust gas pipe area () or/and in the second exhaust gas pipe area () to a liquid collection volume ().
