ABSTRACT:
A catalytic converter assembly for a motor vehicle having an internal combustion engine includes a housing being penetratable by exhaust gas and having at least one inlet, at least one outlet and a given cross-sectional area. A catalytic converter, especially a starting catalytic converter, is disposed in the housing and fills a portion of the given cross-sectional area defining a bypass route remaining free for the exhaust gas traveling past the catalytic converter. At least one flow baffle is disposed in the housing in the form of a flap being adjustable under the influence of temperature. The flap occupies a first position directing the exhaust gas through the catalytic converter at relatively low temperatures. The flap occupies a second position forming a partition between the catalytic converter and the bypass route in at least in some regions for directing the exhaust gas through the bypass route at relatively high temperatures.
