Abstract

An exhaust system for an internal combustion engine, especially for a vehicle, includes an exhaust gas-carrying pipe (12) and a reactant release unit (14) for releasing reactant (R) into exhaust gas (A) flowing in the exhaust gas-carrying pipe (12). The reactant release unit (14) includes a reactant injection unit (20), a reactant delivery unit (18) delivering reactant (R) from a reactant reservoir to the reactant injection unit (20) and a heating unit (24) for heating reactant (R) being delivered to the reactant injection unit (20). The heating unit (24) includes an exhaust gas/reactant heat exchanger unit (26) for transferring heat, being transported in the exhaust gas (A), to the reactant (R).
