This report summarizes the results of a study done to evaluate how 1981 model year motor vehicle emission systems react to ambient temperatures. Five different vehicles with mileages between 500 and 700 miles were tested using the EPA Cold Environmental Test Cell (CETC). Each vehicle was tested according to the Federal Test Procedure (FTP) and the Highway Fuel Economy Test (HFET) at ambient temperatures of 20, 60, 75, and 100 degrees F. The results show that the lower the ambient temperature is, the higher the emission levels for city driving are. In addition, ambient temperatures do not affect exhaust emission levels drastically for highway driving.
