摘要： 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.
摘要翻译： 具有高强度的低微裂纹多孔堇青石蜂窝陶瓷颗粒过滤器，结合非常低的压降，非常高的过滤效率和高耐热冲击性。 很少或没有微裂纹，中等细孔直径和窄孔径分布有助于高强度。 薄的通道壁，高壁渗透性和窄的孔径分布有助于低压降。 具有最小粗孔的细孔径和窄孔径分布有助于提高过滤效率。 高应变公差，MOR / E，有助于高耐热冲击性。 本文公开的颗粒过滤器可用作热气体微粒过滤器，特别是作为内燃机废气微粒过滤器，例如用于汽油直喷式发动机的废气过滤器。
