| Popis: | A test program was conducted to study the effect of ambient conditions on exhaust emissions from a wide variety of automobiles. Ambient temperatures above and below 75 degrees F were found to have significant effects on exhaust emissions. The Diesel and stratified charge cars were affected less than production and catalyst-equipped cars by changes in ambient temperature. The use of air conditioners at the 110 degrees F test temperature led to increased emissions and fuel consumption. Hydrocarbon reactivity and aldehyde emissions were not affected by temperature and were lower from the catalyst cars at all temperatures. /GMRL/ |
