EFFECT OF AMBIENT TEMPERATURE VARIATION ON EMISSIONS AND FUEL ECONOMY -- AN INTERIM REPORT

This paper summarizes the emission and fuel economy data obtained when ten dissimilar cars were run using the 75 Federal Test and the Highway Fuel Economy Test Procedures. The soak and test temperatures used for the modified standard procedures varied from 0 to 110 F. The influence of the cars' air conditioners was also determined. The purpose of the program was to determine how well the emission control equipment designed to be effective at normal FTP test temperatures would work at temperatures ranging betweeb 0 to 110 F.
