An exhaust system for an internal combustion with a catalytic converter connected to the exhaust pipe for cleaning the engine exhaust gas in the presence of a reducing agent also includes a condensation water collector into which the exhaust gases are diverted prior to reaching the catalytic converter. The collector condenses moisture in the exhaust gas to produce liquid water condensate that is held in a reservoir. The water condensate is combined with a reactant capable of forming a reducing agent and the aqueous solution of the reactant is introduced into the exhaust gas upstream of the catalytic converter.

1. An exhaust system for an internal combustion engine having an exhaust pipe for moisture-containing engine exhaust gas and a catalytic converter connected to the exhaust pipe for cleaning the exhaust gas in the presence of a reducing agent, the exhaust system comprising:a condensation water collector for accepting the exhaust gases and condensing moisture therein as liquid water condensate; a reservoir for holding said water condensate; and a storage chamber for combining said water condensate with a reactant to form the reducing agent, said storage chamber having a connection to the exhaust pipe for introducing the reducing agent into the exhaust gas upstream of the catalytic converter.
