Selection of the Best Emulsified Fuel Ratio Compared to Diesel Fuel 2007-01-2138

The main objective of this paper is to identify the best ratio from the emulsified fuel ratios and compare with diesel fuel, based on its performance and emission characteristics. Water - in - Oil type emulsion method has been implemented to produce the emulsified fuel. Emulsified fuels have been prepared with different ratios of 50D: 50E (50 Diesel: 50 Ethanol - 100% Proof), 60D: 40E, 70D: 30E, 80D: 20E and 90D: 10E. From the investigation, it is observed that the emulsified fuel ratios have given the best result than diesel fuel. Also, 50D: 50E has given the best performance result than the other emulsified fuel ratios and diesel fuel. A single cylinder, 4- stroke, water cooled diesel engine has been used to conduct this experiment. It has been observed that there is reduction in smoke density (SD), particulate matter (PM) and exhaust gas temperature with an increase of oxides of nitrogen (NOx) and brake thermal efficiency.
