Abstract
A catalytic converter assembly comprises a housing having an exhaust gas inlet and an exhaust gas outlet. A first chamber enclosed by the housing receives incoming exhaust gas and a second chamber contains a catalyst bed. Gas flows from the first chamber to the second chamber through an exhaust gas passage. A perforated enclosure surrounds the gas passage within said first chamber to induce a region of turbulence in the exhaust gas flow within the enclosure immediately upstream of the passage; An injector extends into the enclosure for injecting a reducing agent into the region of turbulence so that the reducing agent is rapidly dispersed and mixed within the exhaust gas flow before reaching the catalyst bed.
