发明名称 CERAMIC FILTER ELEMENT AND METHOD OF MANUFACTURE
摘要 A method of manufacturing a ceramic diesel particle filter (DPF) and a DPF manufactured by the method, the DPF having a ceramic filter body (1) including gas channels (18, 18′) with planar and porous filter segments (3), which are provided for the exhaust gas stream (2) to flow through them transversely to the face of the filter segments (3). The filter body (1) is formed by sintering at least one ceramic-impregnated fiber web (4) in a firing step under heat such that fibers (5) of the fiber material are burned off and the ceramic material (6) is sintered together to form the porous filter segment (3) between its two surfaces (7, 8). At least one fiber web (4) is corrugated to form the gas channels (18, 18′) and rolled up to form the filter body (1), and the cross section of at least a portion of the gas channels (18, 18′) changes from an inlet end (33) to a discharge end (34).
