Exhaust gas to be cleaned is introduced into a conversion and mixing duct and the exhaust gas flows through the duct along a predetermined longitudinal direction. A reducing agent, such as aqueous urea solution, is injected into the exhaust gas stream in the conversion and mixing duct. The exhaust gas stream is then deflected into a reaction duct which extends parallel to or coaxially around the conversion and mixing duct. The exhaust gas then flows in the opposite direction through the reaction duct. A reduction catalyst is disposed in the reaction duct, where the reducible components of the exhaust gas are reduced. The exhaust gas cleaned in this manner is then discharged from the reaction duct.
A device for cleaning exhaust gas,
In combination with a device for cleaning exhaust gas, the device having a single duct being a combined conversion and mixing duct with a longitudinal axis defined therein and an exhaust gas inlet being obliquely angled to the longitudinal axis and a feed apparatus for injecting a reducing agent in the single duct, a reaction duct extending substantially parallel to the single duct, and a deflector disposed between the conversion and mixing duct and the reaction duct, the deflector deflecting the exhaust gas from a flow direction in the single duct into an opposite flow direction in the reaction duct, a catalytic converter, comprising:
