Study of Vapor Pressures of Gasoline-Alcohol Blends Finds That Dual-Alcohol Blends Can Result in RVPs Identical to That of Gasoline

Green Car Congress

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. A research team from Ford Motor Company and the University of Copenhagen has performed a systematic study of the vapor pressures of single and dual-blends of different alcohols with potential to be used as biofuels, including methanol; ethanol; 1- and 2-propanol; and 1-, 2-, i -, and t -butanol.

Study Finds Strong Synergy Between Spark Ignition Engine Downsizing and Low-to-Moderate Alcohol Blend Fuels

Green Car Congress

A study by engineers from Mahle Powertrain Ltd and BP found strong synergy between spark ignition (SI) engine downsizing and fuel containing low-to-moderate amounts of alcohol, including ethanol and butanol. When alcohol was added to the blend, fuel consumption over the drive cycle increased in direct proportion to the reduction in calorific value of the fuel. The addition of alcohol did not improve excess air tolerance.

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. Ethanol produced the highest unburned alcohol emissions of 1.38 Summary of significant emissions results from the fuel testing.

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

Green Car Congress

The preflame reactions are a strong function of temperature, so evaporative cooling from the fuel can also play a significant role, which is particularly important for fuels containing alcohol. To achieve continued improvement in engine efficiency and CO 2 emissions, it is critical to quantify the roles of fuel octane rating and alcohol content. Alcohol and gasoline-alcohol blends also offer efficiency benefits independent of their octane value.

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

Green Car Congress

The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989. Although it previously used a hydrous ethanol blend, Brazil shifted toward the aforementioned anhydrous ethanol, which is used in a ratio of ethanol to gasoline of 20-24:80-76. Named flex-fuel vehicles (FFVs), these automobiles run on gasoline, ethanol, or any blend of the two. by Brian J. Donovan, CEO Renergie, Inc.
