Abstract
The invention relates to an arrangement for catalytic purification of the exhaust gases of internal combustion engines, especially two-stroke engines, consisting of a jacket tube (1) which is arranged in the exhaust path and in which there is installed a perforated inner tube (3) to form a narrow annular space (5) between the jacket tube and the inner tube. The inner tube (3) is occupied by a catalyst. <IMAGE>
