ABSTRACT:
The exhaust gas equipment for an internal combustion engine contains an exhaust pipe, an exhaust gas cleaner and an adsorption filter, to whose filter body exhaust gas is admitted by a controlled exhaust gas butterfly. In order to prevent damage to the filter due to overheating, in an arrangement of the exhaust gas equipment which is economical in installation space where the adsorption filter is located along the course of the exhaust pipe and a filter body surrounds the latter coaxially, a thermal insulation element is provided between the filter body and exhaust gas flow. The thermal insulation element has transfer openings at least partially outside the exhaust pipe section surrounded by the filter body for guiding the exhaust gas flow through the filter body.
