Combustion characteristics by using multicomponent alcohol blended fuels for the small diesel engine

Nowadays, bio fuel has been expected as substitution of petroleum fuels. Being that it is produced by plants, it has become the sustainable and carbon neutral fuel. Of course, the CO2 emission don’t increase after using them as fuels of the automobiles and industry because of the bio fuels are produced by plants. Based on these factors, the demand of bio fuels has been expected to more spread in recent years. The Ethanol and Butanol have been produced as bio fuels, it is well known that the ignitability of both fuels are lower than that of the light oil, furthermore, it is necessary to improve for the emission characteristics and the heat release rate. This experiment has been carried out to examine the combustion characteristics of a small diesel engine by using the ethanol and butanol (1-butanol, 2-butanol and iso-butanol) for bio alcohol fuel. Furthermore, DGM (Diethylene Glycol Dimethyl Ether) and DMC (Dimethyl Carbonate) are also used for a comparison for bio alcohol fuels.
