Abstract
The University of Denver's remote sensor for on-road motor vehicle carbon monoxide (CO) and hydrocarbon (HC) emissions was used in August and October, 1991, at two different locations in the Denver area. The results of analysis for HC emissions show a similar skewed distribution for the two data sets, although the average HC emissions are very different for the two data sets because different driving modes (no-load/load) existed at the locations where the data sets were collected. There was no significant difference between HC emissions from those vehicles from counties in Colorado with and without an annual emission testing program. The fraction of high emission polluters increases with vehicle age. The evidence suggests that proper maintenance and elimination of tampering are very important even for those new vehicles which are equipped with the latest emission control technology.
