ABSTRACT:
A low-microcracked porous cordierite honeycomb ceramic particulate filter having a high strength in combination with a very low pressure drop, a very high filtration efficiency, and a high thermal shock resistance. Little or no microcracking, a fine median pore diameter, and a narrow pore size distribution contribute to high strength. A thin channel wall, high wall permeability, and narrow pore size distribution, contribute to low pressure drop. A fine pore diameter and narrow pore size distribution with a minimum of coarse pores contribute to high filtration efficiency. A high strain tolerance, MOR/E, contributes to high thermal shock resistance. Particulate filters disclosed herein can be useful as a hot gas particulate filter, and particularly as an internal combustion engine exhaust gas particulate filter, such as an exhaust gas filter for a gasoline direct injection engine.
