||The purpose of this study is two-fold: (1) to determine if the magnitude of transient background levels could be accurately predicted at some point in time by performing total evaporative emission tests; and (2) determine if transient background levels could be artificially lowered to the point of insignificance by elevated temperatures (baking) and or driving. Tests were conducted on 4 test vehicles for which total emissions were measured intermittently over a 3-week period. Between emission measurements certain vehicles were baked and/or driven on a dynamometer to attempt to reduce their background emissions. At the end of this testing at least two repeat background emissions tests were conducted on each vehicle. The results are discussed.
