WHITBY FREE PRESS, WEDNESDAY, APRIL 22,1992, PAGE 21 (NC) A joint research Program of North America's three mgaor auto companies and 14 cil companies bas corne up with 'intriguing' data that mht help regulators ip rove air quality. The initial findings of the prormt mrv air quality reveatl ta canesin gasoline composition can t'avouirably affect vehicle exhaust emions, but they are not equally effective in ail vehicles. For example, 'the program found.that adding oxygenates to gasoline reduced exhaust enilsaons, both hydrocarbons and carbon monoxide. Conversely, it discovered that changing the level of olefins in gasoline doesn't have rnuch effeet on vehicle exhaust emissions. Under the prograin, more than 2,200 emissions tests are being conducted on 53 vehicles, uMUn 29 different reformulated gaones. Tests are being done at laboratories at General Motors, and Ford. Findings from these initial tests will be used in air-quality modeling for Lws Angeles, New York and Dallas-Fort Worth * NOW AT YOUR GOLDEN HORSESHOE * CHEVROLET* GEO~ OLDSMOBILE DEALERS.
