The invention concerns a structure () comprising a filtering member () comprising intake conduits () for the gases to be filtered, and conduits () for extracting the filtered gases, separated from the intake conduits () by porous filtering walls (). The intake conduits () emerge into openings () for discharging respective residues, provided downstream of the respective intake openings (). The openings discharging residues () of the intake conduits () open into a common manifold () for receiving solid filtering residues, forming counter-pressure means for the intake conduits (). Said manifold () is isolated from the extracting conduits (). The invention is applicable to particulate filters for exhaust gases of a motor vehicle diesel engine.

Structure for filtering an internal engine exhaust gases and associated exhaust line

This invention is a high strength, thermal shock resistant, high purity siliconized silicon carbide material made from siliconizing a converted graphite SiC body having at least 71 vol % silicon carbide therein.

High purity, siliconized silicon carbide having high thermal shock resistance

This invention relates to a siliconized silicon carbide-base composite comprising at least about 71 vol % converted-graphite SiC matrix having open porosity, wherein the open porosity of the matrix is essentially filled with silicon, and the composite has a total metallic impurity content of no more than 10 ppm.
