Abstract |
An exhaust emissions test program was conducted in Portland, Oregon on a sample of privately-owned 1975-77 model year passenger cars. The objective of the program was to collect data on the correlation between short inspection tests and the 1975 Federal Test Procedure (FTP). Fifty-nine different groups of cars were tested, in numbers ranging from 32 to 45 cars per group, for a total of 2207 cars. In its as-received condition, each car was subjected to the inspection employed by the Oregon Department of Environmental Quality (DEQ), which includes an idle-mode exhaust concentration measurement, at a DEQ inspection station. Another idle-mode test, the FTP, the Federal Short Cycle (FSC) and the Federal Three-Mode (F3M) tests were then run on each car at an emissions test laboratory. About half of the cars were also subjected to the FSC and F3M tests conducted by DEQ personnel at a DEQ inspection station. Emissions and fuel economy data are presented for each vehicle group and for model year and DEQ pass-fail status within each group. Correlation coefficients have not been calculated. |
