The invention relates to a static mixer for an exhaust gas system of an internal combustion engine-driven vehicle, with a plurality of flow guide elements which influence the flow of an exhaust gas stream and which are inclined at a given angle relative to the mixer plane and are held in the exhaust gas channel by means of at least one retaining strip. According to the invention the at least one retaining strip is made resilient at least in partial regions and/or is elastically supported in the plane of the mixer.

In a filter consisting of hollow cylindrical open-pore ceramic foam and an end plate made of gas-impermeable material, as an insert in a filter cup for cleaning exhaust gases of diesel engines, in which the exhaust gases flow through the active filter section essentially perpendicularly to the cylinder axis, a larger ceramic foam portion such as is used e.g. as an exhaust filter for a diesel engine for a truck or passenger service bus can be made from one piece only with increased requirements, because the necessary dimensional accuracy necessitates increased requirements, and hence the economy of using the ceramic foam is greatly impaired. Also, the back pressure increases considerably. In a filter of this type these disadvantages are avoided by providing a filter which includes two or more axially arranged ceramic foam cylinder elements between which is located a lamella made of gas-impermeable material with at least approximately the same diameter as the ceramic foam cylinder elements and with at least one opening in the ceramic foam cylinder-free region.
