摘要:
A filter for filtering particulate matter (PM) from exhaust gas emitted from a compression ignition engine, which filter comprising a porous substrate having inlet surfaces and outlet surfaces, wherein the inlet surfaces are separated from the outlet surfaces by a porous structure containing pores of a first mean pore size, wherein the porous substrate is coated with a wash coat comprising a plurality of solid particles comprising a molecular sieve promoted with at least one metal wherein the porous structure of the wash coated porous substrate contains pores of a second mean pore size, and wherein the second mean pore size is less than the first mean pore size.
摘要(中):
一种用于从压缩点火发动机排放的废气中过滤颗粒物质(PM)的过滤器,该过滤器包括具有入口表面和出口表面的多孔基材,其中入口表面通过多孔结构分离,该多孔结构含有孔 第一平均孔径,其中多孔基材涂覆有包含多个固体颗粒的洗涤涂层,所述固体颗粒包含用至少一种金属促进的分子筛,其中所述洗涤涂覆的多孔基材的多孔结构含有第二平均孔径的孔, 并且其中所述第二平均孔径小于所述第一平均孔径。
