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

Green Car Congress

Results of a study led by a team from the National Renewable Energy Laboratory on the impact of butanol-gasoline blends on light-duty vehicle emissions suggest that widespread deployment of n-butanol or i-butanol in the gasoline pool could result in changes to the estimated emissions of alcohols and carbonyls in the emissions inventory.

Team from GM, Ford, FCA reviews how to calculate engine efficiency benefits of high octane fuels

Green Car Congress

Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value. Practically, however, the range of regular-grade gasoline in the US is 89 to 96 RON; vehicles need to be designed to accommodate fuel with the lowest expected octane rating. Higher octane fuels and legacy vehicles.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The Brazilian government’s dedication to the ethanol industry declined and incentives given by the government wore off, causing hydrous ethanol-fueled vehicle production to decline in the late 1980s to early 1990s. Named flex-fuel vehicles (FFVs), these automobiles run on gasoline, ethanol, or any blend of the two. 40 CFR § 80.27
