摘要：
The exhaust gases from an internal combustion pass through an exhaust system including a catalytic device that eliminates the pollutants from the exhaust. The device includes a sleeve having a catalytic surface with an abrasive structure by which periodically the catalyst surfaces on the sleeve are reactivated to assure adequate effectiveness.
