| Popis: | Experiments were performed to examine cluster formation when simulated engine exhaust gas passes through an atmospheric pressure plasma discharge cell at 180 °C. The gas composition included N2, NO, CO, CO2, C3H8, C3H6, Ar, H2, H2O, O2 and SO2. Aerosol particles or clusters were measured after the gas was treated with a dielectric barrier discharge, although the quantity of clusters generated was several orders of magnitude smaller than normal engine emissions. The clusters were not formed when water was not present in the mixture. The number and size of clusters increased when hydrocarbons were not present, although the quantity was still very small. Methods to describe cluster formation phenomena are discussed. |
