Exhaust emission control device

The invention relates to an exhaust emission control device for internal combustion engines operated with leaded and/or unleaded fuel. Since in the current situation a transitional phase is to be anticipated in the case of motor vehicles, in which both leaded and unleaded fuel is used, this means a considerable shortening of the service life of conventional catalytic converters. In order to increase this service life of conventional catalytic converters, a device is created in which due to cross-section continuity as flow ducts become smaller or whether or not there are internal cross-connections the greatest possible inherent activation coupled with the smallest possible pressure loss, is achieved and in addition there is a multi-stage filtration effect for solid particles, in which clogging is largely prevented.
