Measurement of running loss emissions from in-use vehicles (CRC project E-35). Final report
Technical Report
·
OSTI ID:678874
A total of one hundred and fifty randomly procured in-use vehicles were tested in Mesa, Arizona during the summer months of 1997. Running loss hydrocarbon emissions were measured using a dynamometer enclosed in an evaporative emissions enclosure (SHED). New vehicle evaporative emission certification test equipment specifications, test procedures, and quality control limits were used, with specified exceptions required to test publicly owned in-use vehicles. A thorough inspection of vehicle components related to evaporative emissions was performed on each vehicle following the initial test with the vehicles in the `as-received` condition. Thirty vehicles were selected for repairs and were retested following repairs. Ten vehicles were selected for as-received replicate testing.
