Abstract (en)
[origin: WO2005066469A1] The invention relates to a particle filter (1) consisting of an envelope (2) and at least one body (3) comprising at least one metallic fibrous layer (4) that is arranged in such a way that a plurality of spatially separated flow paths (5) are formed through the body (3), said flow paths respectively comprising a flow restrictor (6) at at least one point. The inventive particle filter is characterised in that the at least one metallic fibrous layer (4) has a superficial heat capacity of between 400 and 1200 joules per Kelvin and square metre [J/Km2], providing the particle filter with an especially high particle storage capacity and regeneration capacity.
