Research was conducted to develop test methodology to determine the effect of fuel and fuel additives on control devices for automotive exhaust emissions. Monolithic and beaded noble metal catalysts were tested on engine dynamometers. Two fuel additives, a manganese octane improver and an amine detergent, were evaluated and the data compared with data from baseline fuel tests. The results of this comparison were then compared with results obtained from three vehicles equipped with beaded catalysts operated on the three fuel combinations. A testing procedure is recommended. In addition to gaseous emissions, a very limited number of particulate samples was collected and analyzed for trace elements. No significant catalyst attrition was noted.
