Abstract |
Particulate emissions from a vehicle equipped with a variety of commercial and prototype catalyst systems were measured and characterized. Nine catalysts including four monolithic and three pelleted oxidation catalysts and two NO(x) reduction catalysts were screened on three test fuels over the 1975 FTP driving cycle and three study states. Particulate emissions increased due to the formation of sulfuric acid from exhaust SO2. This sulfuric acid together with bound water accounted for most of the particulate emitted. Sulfate was the only form of sulfur detected in the particulate. Substantial differences between oxidation catalysts in their sulfuric acid formation tendency were detected. Additional information on the particle size distribution and metals content of the particulate is included. |
