Investigations of the impact of 10% ethanol blended fuels on performances of sold gasoline vehicles in the Japanese market Feb 22, 2011 Toshiyuki Hirose ADVANCED TECNOLOGY AND RESEARCH INSTITUTE JAPAN PETROLEUM ENERGY CENTER JAPAN AUTO-OIL PROGRAM Objectives Japans energy strategy requires reducing oil dependence in transport sector, so that introduction of biofuels, especially for bio- ethanol, is a key solution to fuel diversification. Based on the recognition that research on the use of E10 gasoline should be conducted, technical issues for future fuels and motor vehicles and their measures are being examined. * E10 gasoline: a blend of 10% ethanol and 90% gasoline 2 Characteristics of ethanol used for blending into gasoline Production from carbohydrates of sugar canes and other feedstocks through fermentation method Single chemical substance expressed by C H OH H: Hydrogen 2 5 (MW: 46) Boiling point: 78C C H -O-H C: Carbon 2 5 O: Oxygen High oxygen content (35 mass%) Strong polarity (similar to Molecules have locally strong polarity (-O-H), characteristics of water) so that the characteristics are significantly different from petroleum fuels Fuel characteristics to be considered Possible issue with vehicles nSignificant increase in
