Abstract
An emissions treatment device includes a substrate having multiple parallel channels/layers of a porous material, the channels/layers including a first group of channels/layers at least partially open along their length from an upstream end to a downstream end, and a second group of channels/layers that are at least partially open at the downstream end and may be substantially blocked at an upstream end, the parallel channels having complementary geometries and/or sizes. Coated metallic fibers or fleece facilitates flow of exhaust through walls of the first group into the second group of channels. Flow diverters or scoops may be formed in the walls between the first and second groups of channels to divert exhaust flow from the first group to the second group of channels. Catalyzed mesh sheets may be supported by perforated stainless steel sheets containing small passages and/or scoops to complement the useful wallflow by structure and flow design.
