Abstract
A catalytic reactor for an internal combustion engine having a cooling jacket surrounding multiple catalyst elements. A thermal barrier layer is formed between the catalyst elements and the cooling jacket to prevent over cooling of the catalyst elements. The thermal barrier layer can be formed from insulating elements such as fibrous material, a plurality of annular rings disposed around the catalyst elements, a corrugated layer, or can be formed by an empty space.
