heal.abstract This paper describes the impact of two exhaust after treatment devices, an oxidation catalytic converter and a diesel particulate filter, on the particulate emissions of a heavy-duty diesel engine, the emphasis being on diesel particulate composition and size distribution. The analysis showed that the catalytic converter did not alter the size distribution significantly, except for an increased production of nanosized particles below 30 n miles in mean diameter. On the other hand, the ceramic monolith wall flow filter reduced the emitted particle number up to 100 times. The results again indicated that a diesel particulate filter can also increase the number of nanosized particles. Further investigations, however, revealed that the formation of nanosized particles downstream of the oxidation catalytic converters and diesel particulate filters, respectively, is biased by inadequate sampling conditions. As long as realistic sampling conditions are applied, both catalyst and filter reduce particle emissions over the entire size range. en
