Title:
PM浄化装置の製造方法
Document Type and Number:
Japanese Patent JP4839773
Kind Code:
B2
Abstract:
To provide a particulate matter purifying device which is capable of providing excessive deposition pf particulate matter. In the particulate matter purifying device, a catalyst element 11 is carried on a porous filter substrate 10 through which an exhaust gas passes. The particulate matter purifying device traps particulate matter contained in the exhaust gas, and oxidizing the trapped particulate matter to remove. This particulate matter purifying device is characterized in that active oxygen producing fine particles 12 are carried on a surface of the filter substrate 10 between the catalyst elements 11. Therefore, the particulate matter is partially damaged by the active oxygen produced by the active oxygen producing fine particles 12. Consequently, oxidization of the particulate matter is promoted so that deposition of the particulate matter is prevented or minimized.
