ABSTRACT:
An electrically conducting ceramic composition is described which can be utilized in an exhaust gas filter. The ceramic composition is compacted into discs or ceramic plates, are subsequently fired or sintered and then equipped with electrodes. Electrode leads are attached to the sintered filter discs or plates bearing electrodes which are subsequently connected to a power source. The ceramic filter discs or plates are supported and enclosed in a metallic housing. In another embodiment an insulator ring is placed between the housing and the ceramic filter plate. The housing enclosing the ceramic filter or filters, and equipped with electrodes and appropriate leads, is incorporated in the exhaust system of an internal combustion engine. The ceramic filter is used for trapping combustible carbon particles carried by the exhaust gas emanating from the engine. The carbon particles collected by the filter can be eliminated by heat generated electrically by means of an electrical current being passed through the filter between the electrodes when so desired.
