Abstract
In a solid particulate filter of honeycomb structure comprising a matrix of thin, interconnecting porous walls defining groups of inlet and outlet cells, the characteristics of fluid flow through a first subset of the thin walls, being shared in common between adjoining inlet and outlet cells, are differentially controlled relative to that of a second subset of thin walls, being shared in common between adjoining inlet cells, by forming each subset with uniform thicknesses which differ between the subsets. In a brittle solid particulate filter of honycomb structure having opposing inlet and outlet end faces and cells extending therebetween, improved thermal shock capability is provided by selecting outlet cell geometries and orientations with respect to the inlet cells so as to form flexing or movable joints between some or all of the thin walls shared by adjoining inlet and outlet cells and the thin walls shared between adjoining inlet cells.
