PARTICULATE FILTER WITH CATALYST |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a particulate filter with a catalyst which has high combustion efficiency of PM and can effectively suppress CO emission. <P>SOLUTION: The filter includes as the catalyst: a Pt-supported active oxygen discharge material in which an active oxygen discharge material supports the Pt; and a Pt-supported alumina in which an active alumina supports the Pt. The Pt-supported active oxygen discharge material and the Pt-supported alumina are separated in an upstream region 1a and a downstream region 1b in the filter 1, and the former is supported in the upstream region 1a and the latter is supported in the downstream region 1b. <P>COPYRIGHT: (C)2013,JPO&INPIT |
