In practical gasoline engines it is necessary to achieve low emissions and low fuel consumptions with high load operation. Several techniques were developed for reducing the emissions and the fuel consumptions from gasoline engines, such as EGR (exhaust gas recirculation) and Ultra lean combustion [1, 2]. Especially, in automotive gasoline engines, low-particulate and low-NOx emissions are very much needed by using alcohol blend fuels and vegetable oil. Nevertheless, there are only few data available for reducing the emissions and fuel consumptions of small gasoline engines by using blended fuels. As the first step in this study, experiments have been carried out to examine the influence of alcohol-blended fuels on combustion characteristics for small gasoline engines. The fuels used in this study are gasoline, methanol, ethanol, propanol and butanol. The addition of alcohol ratio are changed by mixing the volume of alcohol in gasoline and the addition ratios are from 0 to 30 vol% in the fuel. The main conclusions are as follows: 1) The NOx emissions for all the alcohol blend fuels are smaller than that of gasoline. 2) The heat release rate increases with addition of alcohol fuel under higher load conditions for small gasoline engines.
