These years, air pollution caused by exhaust gas from automobiles has been problematic. So diesel engines have been paid attention from the viewpoints of thermal efficiency and low emissions of CO2. However, soot and nitrogen oxides contained in the exhaust gas of diesel engines have become a social problem. Therefore, we focused on the improvement of fuel itself. This time, We focused on emulsion fuel. In this study, we operated a diesel engine with W / O type emulsion fuels, and verified the effect of water droplet diameter profile in emulsion fuel on power characteristics and the exhaust gas composition of diesel engine. As a result, a trend was seen both power characteristics and exhaust gas components as the water droplet diameter profile is broadened.
