The use of copper fuel additives results in a higher catalytic activity for soot oxidation compared with the use of powdered copper oxide catalysts as a model for catalytic coatings on particulate filters. Diesel engine exhaust tests revealed that with the use of copper fuel additives, constant temperatures of 365 - 435°C are sufficient to establish an equilibrium between soot collection and soot oxidation. When a copper oxide coating on a filter is used, significantly higher temperatures are needed to burn the accumulated soot from the filter.
This study shows that copper fuel additives have a high enough activity and are in principle suitable for application in practice. Explanations for this high activity are given.
