CATALYSED PARTICULATE FILTER AND METHOD FOR THE PREPARATION OF A CATALYSED PARTICULATE FILTER |
摘要 |
Wall flow particulate filter catalysed at its inlet side with a catalyst having activity in the removal of residual hydro-carbons and carbon monoxide and catalysing at rich burn engine operation conditions the reaction of nitrogen oxides with hydrogen and/or carbon monoxide to ammonia and catalysed at its outlet side with a catalyst having activity in the selective reduction of NOx by reaction with ammonia being formed in the inlet side. |
