Exhaust gas system for an internal combustion engine

An exhaust gas system for an internal combustion engine, the exhaust gas system comprising:

• a first exhaust gas treatment unit having an upstream inlet region and a downstream outlet region;
• at least one second exhaust gas treatment unit having an upstream inlet region and a downstream outlet region;
• and,
• a connecting housing connected to said downstream outlet region of said first exhaust gas treatment unit and to said upstream inlet region of said second exhaust gas treatment unit, said connecting housing including a first housing element having an inlet opening and an outlet opening, said downstream outlet region of said at least one first exhaust gas treatment unit being connected to said connecting housing in a region of said inlet opening of said first housing element, said upstream inlet region of said at least one second exhaust gas treatment unit being connected to said connecting housing in a region of said outlet opening, said connecting housing including a second housing element which, with said first housing element, encloses a connecting volume, through which exhaust flows;
• a component provided by said connecting housing and having an outer wall delimiting said connecting volume, said outer wall including said first housing element and said second housing element;
• said outer wall having an inner side facing said connecting volume;
• said component supporting at least two shielding elements on said inner side of said outer wall, a first shielding element and a second shielding element of said at least two shielding elements being arranged in an adjoining region wherein they mutually partially overlap and conjointly define an intermediate space therebetween, said first and second shielding elements being provided on an inner side of said second housing element in a region which lies in accordance with at least one of the following:
• i) opposite said inlet opening;
• ii) opposite said outlet opening;
• and,
• iii) opposite a transition region formed between said inlet opening and said outlet opening;
• and,
• said outer wall and said at least two shielding elements conjointly defining an intermediate space therebetween;
• said exhaust gas system further including:
• at least one first connecting molding provided on a shielding element of said at least two shielding elements and directed toward said outer wall;
• and,
• at least one second connecting molding provided on said outer wall and directed toward a shielding element of said at least two shielding elements and fixedly connected to said at least one first connecting molding.
