Utilization of Bioethanol in E85 Fuel
Institute of Chemical Technology, Prague
The E85 fuel containing 70?85 vol. % of ethanol is intended for flexible fuel vehicles which consume ethanol – gasoline mixtures. Due to very different properties of ethanol and hydrocarbons, special requirements for preparation of the mixtures must be met. In the mixtures, highly volatile hydrocarbons can be used. The problems of vapour pressure and phase stability of the E85 fuel are described and discussed.
