초록 ▼

A honeycomb body, especially a particulate filter, particularly for motor vehicle exhaust purification, includes inner walls defining passages with an entry and exit. Cavities free of walls in at least one subregion contain at least one spherical free space having a largest cross-sectional area at least 10 times a cross-sectional area of the passages in the subregion. The honeycomb body is wound, twisted or layered from at least one metal sheet having layers with a structuring forming the passages, at least in the subregion. The sheet-metal layers have holes with an area greater than 10 times the cross-sectional area of the passages in the subregion. The holes form cavities in at least 5 successive layers overlapping with an area at least 10 times the cross-sectional area of the passages in the subregion. The holes are double or more than triple the hydraulic diameter of the passages opening into the cavity.

The invention claimed is: 1. A honeycomb body, comprising:an entry surface and an exit surface defining a honeycomb body width therebetween;subregions disposed between said entry surface and said exit surface;an inner region of said honeycomb body;layers, including adjacent layers, extended continuously across said honeycomb body width, having inner walls defining passages leading from said entry surface to said exit surface, said passages having a mean cross-sectional area;a plurality of cavities disposed in said layers in at least one of said subregions, said cavities each being defined by a plurality of mutually aligned holes in said adjacent layers, being free of said inner walls and being shaped and dimensioned to contain at least one spherical free space, said plurality of cavities being accumulated in said inner region of said honeycomb body;said at least one spherical free space having a largest cross-sectional area amounting to at least 10 times said mean cross-sectional area of said passages in said at least one subregion; andnot all of said passages intersect a cavity.
