ABSTRACT:
A catalytic converter for purifying the exhaust gases from an internal combustion engine, wherein a plurality of catalytic layers are arrayed in series and spaced apart by a predetermined distance from each other, and bypass paths are provided in such a way that except for the last catalytic layer, a part of the exhaust gases may bypass each catalytic layer without making contact therewith and may directly flow into the next catalytic layer.
