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

Green Car Congress

NOVEMBER 26, 2013

Ethanol produced the highest unburned alcohol emissions of 1.38 mg/mile ethanol, while butanols produced much lower unburned alcohol emissions (0.17 mg/mile n-butanol, and 0.30 mg/mile i-butanol); these reductions were offset by higher emissions of carbonyls.
