Summary:

Catalyzed diesel particulate filter systems have now been successfully introduced and implemented in Europe. In the meantime, automotive manufacturers are working on the second generation of catalytic filters with the aim of reducing the overall system costs. In particular savings in precious metal costs are focussed by the use of highly-active catalysts which are stable at high temperatures. A possible approach here is the implementation of oxidation catalysts and catalytically coated filters based on platinum and palladium. In this context, the functio-nality of platinum/palladium-based, catalyzed filters was investigated by numerous measurements on a synthetic gas and an engine bench as well as by vehicle tests on a roller dynamometer. The HC/CO oxidation activity, the poisoning resistance towards sulfur and the desulfurization capability, the exothermic behaviour due to the conversion of subsequently injected hydrocarbons and the NO2 formation potential were examined in detail. The durability of Pt/Pd based systems was demonstrated in several vehicle tests
