摘要： A device for the aftertreatment of exhaust gases from an internal combustion engine has a tubular first flow section, a deflecting region and a annular second flow section, the second flow section being arranged between an inner wall delimiting the first flow section and an outer wall delimiting the second flow section. At least one annular honeycomb body is arranged in the second flow section, and at least one annular heating disk is arranged in the second flow section, the heating disk being electrically contactable by at least two electrical feedthroughs, which are arranged on the outer wall.
