Abstract
For the NOx-assisted diesel soot abatement, the trend of decreasing engine-out NOx emission will become a serious threat unless NOx can effectively be utilised. A filter candidate consisting of Pt-containing ceramic foam and a wall-flow monolith configuration (an optimised catalytic filter) is proposed to employ an optimal usage of NOx. By design this configuration is capable to employ two stages of filtration, namely: deep bed filtration on the foam and surface filtration on the wall-flow monolith. At the same time, two modes of soot oxidation reactions will operate. In Pt/ceramic foam multiple NO oxidation to NO2 and trapped diesel soot oxidation by NO2 take place, while part of NO2 is released as NO2-slip and this NO2-slip is subsequently utilised to oxidise trapped soot on a wall-flow monolith. In laboratory tests, this concept is clearly demonstrated that it outperforms the activity of conventional regenerating trap, based on upstream NO-NO2 conversion.
