Measurements of the cold start and warm-up emissions of more than one hundred in-use motor vehicles in the Fairbanks area were performed during the winter of 1974-75. It was found that, for densely populated areas of the city where large numbers of vehicles are started and allowed to warm-up daily, the major portion of the carbon monoxide (CO) emitted to the ambient is produced during the cold start and warm-up phase of vehicle operation. It appeared that none of the pollution control devices presently in common use were effective in reducing the cold start CO emissions, and that older vehicles were not greater emitters of CO than were the newer vehicles. This investigation also shows that the most effective way of reducing cold start emissions on a per vehicle basis is to utilize smaller engine size.
