NREL study probes emissions impact of butanol-gasoline blends in light-duty vehicles

Green Car Congress

Summary of significant emissions results from the fuel testing. Given equivalent deployment of butanols and ethanol, the results suggest emissions of unburned alcohols would decrease, but carbonyl emissions would increase; some of these compounds have poorly understood health effects, they note.
