ABSTRACT:
A typically monolithic particulate filter including a highly porous block made primarily of intertangled polycrystalline mullite fibers, a set of channels formed through the block, and a set of porous walls separating adjacent channels. Exhaust gas is flowed through the channels and interacts with the walls such that particulate matter carried in the exhaust gas, such as soot particles, is screened out by porous fibrous mullite walls.
