Popis:	An exploratory study was carried out with respect to the performance of a copper fuel additive in combination with monolithic wall flow filters for the removal of soot from diesel exhaust gas. Cordierite filters, copper coated cordierite filters, and silicon carbide filters were studied. Model experiments have been performed to investigate the influence of contact between soot and catalyst on the oxidation rate. The observation that the effect of a copper coating on the filter performance is marginal compared to the influence of the copper additive is supported by the model experiments. The contact between soot and catalyst is a crucial parameter for the performance of a catalyst. The contact between a copper coating applied to a filter and soot collected on this filter is not sufficient to achieve continuous, complete soot oxidation under realistic diesel engine exhaust conditions.
