Data on exhaust emissions were obtained from two vehicle fleets (1970 and 1979 model-year) operating over a range of ambient temperatures. The work is providing a baseline against which current-production vehicles can be compared, thus enabling a more complete assessment of automotive emissions reduction achievements. The baseline fleet represented the 1970 MY nationwide mix. The 37 cars were tested at 25, 75, and 100 F over the urban Federal Test Procedure, Highway Fuel Economy Test, and New York City Cycle. Both temperature and driving cycle were found to have significant effects on exhaust emissions. The conditions which yielded the greatest adverse effects on emissions were (1) low temperature--urban driving cycle, and (2) high temperature--New York City driving cycle. The data also indicate that the use of air conditioners causes increased emission levels. These results apply directionally to both fleets. However, the influences of temperature and driving cycle on emission rates of the current model-year fleet were significantly less than on those of the baseline fleet.
