The objective of the overall program was to provide light-duty vehicle emission data. These data are used by the EPA to calculate average emission factors from which emission source inventories and emergency episode pollution abatement procedures are developed. Other objectives included the development of short cycle emission test data and on the costs and effectiveness of high altitude vehicle maintenance specific to the Denver site. The short cycle evaluation task data are used by the EPA to establish correlations between selected short cycle emission tests and the more sophisticated emission testing procedures. Tests were performed on a sample of six-hundred and seventy-nine (679) 1972 through 1976 model-year vehicles operating in the Denver metropolitan area. Ten 1975 model light-duty trucks were used in connection with emission factors development, short cycle evaluation and a task designed to develop data on emission related costs and effectiveness of high altitude vehicle maintenance specific to the Denver area.
