Abstract

An exhaust system, especially for an internal combustion engine of a vehicle, includes an exhaust gas-carrying duct (14) and a reactant injection device (20) for injecting reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying duct (14). Downstream of the reactant injection device (20), a mixer device (22) supports the mixing of reactant (R) injected by the reactant injection device (20) with exhaust gas (A) flowing in the exhaust gas-carrying duct (14). Downstream of the reactant injection device (20) and upstream of the mixer device (22), a reactant heating device (24) extends in the exhaust gas-carrying duct (14). The exhaust gas (A) flows in and reactant (R) injected through the reactant injection device (20) flow around the heating device (24).
