DIESEL PARTICLE FILTER WITH A CERAMIC FILTER BODY

摘要

Disclosed is a diesel particle filter with a ceramic filter body and a method for producing the filter body. The ceramic filter body includes gas channels provided in a filter section with planar and porous filter walls. The filter walls provide throughflow of the exhaust gas flow perpendicular to the surfaces thereof. The filter body includes at least one catalytic section for catalytic purification of the exhaust gas flow. The filter body together with the filter section and the at least one ceramic section are made in one-piece from at least one ceramic impregnated fiber web. Gas channels are formed by sintering the fiber web at a temperature such that fibers of the fiber material are burned away and the ceramic material is monolithically sinter-bonded in one-piece with the at least one catalytic section and the filter section to produce the filter body.
