An exhaust system, especially for an internal combustion engine of a vehicle, includes an exhaust gas-carrying duct () and a reactant injection device () for injecting reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying duct (). Downstream of the reactant injection device (), a mixer device () supports the mixing of reactant (R) injected by the reactant injection device () with exhaust gas (A) flowing in the exhaust gas-carrying duct (). Downstream of the reactant injection device () and upstream of the mixer device (), a reactant heating device () extends in the exhaust gas-carrying duct (). The exhaust gas (A) flows in and reactant (R) injected through the reactant injection device () flow around the heating device ().

Exhaust system, especially for an internal combustion engine of a vehicle

An exhaust gas mixer arrangement for mixing exhaust gases of an internal combustion engine with an additive comprises an exhaust gas flow duct () with an inlet area () arranged upstream and with a discharge area () arranged downstream. The exhaust gas flow duct () is bent in a coil-like manner at least in some areas between the inlet area () and the discharge area ().

Exhaust gas mixer arrangement

An injection device (), for introducing a reducing agent () into an exhaust gas stream () of an exhaust system () of an internal combustion engine (), has an exhaust pipe () for guiding the exhaust gas stream (), which has a connecting piece opening () in a wall (). A connecting piece () is inserted with an inner end () into the connecting piece opening () and is provided for connecting an injector () at an outer end (). Simplified assembly is achieved if the connecting piece () has, at an inner end (), a laterally projecting, fully circumferentially extending collar (). The collar () is in contact, on an inner side () of the wall (), with an opening edge () enclosing the connecting piece opening () and is welded to the wall ().

Injection device and corresponding method for manufacturing same

A mixer (), for an exhaust system () for mixing and/or evaporating a liquid () in an exhaust gas flow (), especially for an SCR system (), includes a plurality of guide blades () arranged in a star-shaped pattern. Simplified manufacturability of the mixer () is achieved if the guide blades () are connected each with a centrally arranged core () radially on the inside and if the guide blades (). The guide blades () and the core () are formed by an integral cast part ().
