In recent years, environmental issues such as global warming and air pollution is a serious problem. Interested in environmental issues has been growing worldwide. In this study, experiments have been carried out to examine the influence of alcohol addition fuels on combustion characteristics and combustion products for small gasoline engine. The fuels used in this study are blended fuels of gasoline and the alcohol (methanol, ethanol, propanol and butanol). The main conclusions are as follows;1) The NOx emissions decrease with addition of alcohol (ethanol, propanol and butanol) in fuels under these experimental conditions.2) The heat release rate increases with addition of alcohol fuel under high load conditions for a small gasoline engine.
