Abstract
The present invention relates to a catalytic converter element having a plurality of essentially parallel channels through which gas flows during operation of the catalytic converter element. The channels are bordered by channel walls which have a catalytically active coating arranged thereon in at least some areas where it is exposed to the gas. In some channels the coating thus begins with an axial offset from the admission end. This allows an improved temperature management within the catalytic converter element.
