A test program was conducted to study the effects of ambient conditions on exhaust emissions from a variety of automobiles. Twenty-six cars, ranging from 1967 models through catalytic converter-equipped prototypes and cars powered by unconventional engines (rotary, Diesel, and stratified charge), were tested at 20, 50, 75 and 110 degrees F. Test procedure was the 1975 FTP, but with engine hoods closed and cooling air flow keyed to vehicle speed. HC, CO, NOx, total aldehydes, and reactive hydrocarbons, plus carbon balance fuel economy, were measured. The results are discussed.
