ABSTRACT:
In a filter consisting of holoow cylindrical open-pore ceramic foam cylinder elements 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, bending moments which lead to breakage of the ceramic foam cylinder elements occur during fitting of the elements due to lack of surface evenness and plane-parallelism of the end faces. A filter of the aforementioned kind, in which the end faces of the ceramic foam cylinder elements are provided with temperature-resistant and thermal shock-resistant layers of material which are plastic at room temperature, avoids the bending moments.
