ICCT study concludes no technical barriers to use of higher blends of ethanol

Green Car Congress

With stagnating demand for gasoline due to rising fuel economy in the nation’s fleet and other factors, further increases to US ethanol consumption would require the use of higher blends of ethanol, either in conventional vehicles or in flex-fuel vehicles (FFVs) designed to tolerate blends of up to 85% ethanol (E85).

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

Green Car Congress

The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. 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. Donovan, CEO Renergie, Inc.

Elio Motors unveils engine prototype for 84 mpg highway 3-wheeler

Green Car Congress

As the team began to dive into some of the details and changes to meet the desired Elio targets, it found that the Geo Metro engine would not meet the fuel efficiency targets to enable the vehicle fuel economy goal of 84 mpg highway. The Elio engine uses a cooled Exhaust Gas Recirculation (EGR) system. Current prototype of the Elio.
