The utilization of biodiesel fuels (BDF) from renewable sources is expected to reduce carbon dioxide emission from internal combustion engines. However, the cold flow performance of BDF is generally less favorable than petroleum diesel fuel. On the other hand, fatty acid methyl esters, which are the constituents of BDF, are highly soluble with ethanol. Previous research has shown that blending ethanol to BDF improves the cold flow performance of BDF and reduces soot emission. Simultaneous reduction of soot and NO_x was also achieved by combining the ethanol blending and EGR. This paper analyzes the effect of enhanced premixing by the ethanol blending in a bottom view type optical access engine. The characteristics of unregulated exhaust gas emissions such as acetoaldehyde are also analyzed in the ethanol blended BDF combustion.
