2009 journal article

Comparison of Flexible Fuel Vehicle and Life-Cycle Fuel Consumption and Emissions of Selected Pollutants and Greenhouse Gases for Ethanol 85 Versus Gasoline

JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION, 59(8), 912–924.

By: H. Zhai n, H. Frey  n, N. Rouphail n, G. Goncalves & T. Farias

Contributors: H. Zhai n

MeSH headings : Air Pollutants / analysis; Bioelectric Energy Sources; Carbon Dioxide / analysis; Ethanol / chemistry; Gasoline / analysis; Models, Theoretical; Vehicle Emissions / analysis
TL;DR: Evaluated differences in fuel consumption and tailpipe emissions of flexible fuel vehicles (FFVs) operated on ethanol 85 (E85) versus gasoline imply that replacing gasoline with E85 reduces CO emissions, may moderately decrease NOx tail pipe emissions, and may increase HC tailpipe emission.
