ABSTRACT:
A device for controlling engine exhaust emission for use on an internal-combustion installation, in which a soot filter is arranged in an exhaust-gas system. The soot filter is made up of a flexible filter band that is traversed by the flow of exhaust gas in a first zone and which can be moved forward and renewed, continuously or intermittently, by a drive mechanism. The filter band is supported at least in the first zone by a flexible, moveable, endless conveyer belt that is permeable to gas and that absorbs tensile stresses. The filter band and the particles separated out of the exhaust gas by the filter band are burned together in a second zone.
