Alternate fuel influences on emission test procedures
The vehicles were tested on neat methanol and a blend of 5.5% mass isopentane in methanol for improved cold weather performance. Modifications of testing procedures for gasoline-powered vehicles were required. From analysis of the exhaust and other calculations, the following conclusions seem most significant: (a) the higher water content in the exhaust of alcohol fueled vehicles may result in condensation the dilute exhaust mixture. Further study is needed; (b) higher aldehyde emissions of the alcohol fuels relative to that of gasoline is the greatest environmental drawback to the use of alcohol fuels. Further understanding of their contribution to photochemical smog production is needed. 6 tables.
