Abstract
The existence of water with inside biodiesel–diesel blended fuel in the form of W/O emulsion drops the percentage of NOx and SD due to micro-explosion phenomena. Considering this in mind in the current work, optimum blend of dual bio-diesel with diesel blend (C15R15) has been selected directly based upon previous work carried out on engine performance, combustion and emission of duel fuel optimum percentage using MCDM technique. This optimum blend has been used for the preparation of W/O emulsified fuel. In emulsified fuel, water percentages were varying from 1 to 5%, and different emulsified sets of fuel blend are prepared based on HLB ratio ranging from 4.3 to 6. The current experiments were carried out on VCR single-cylinder, four-stroke, water-cooled diesel engine operated under varying load conditions 0–110% at constant operating speed (1500 rpm) with injection time 20° BTDC. Based upon the engine performance, combustion, and emission analysis and then multiplying them with load factor, the best optimum emulsified fuel has been selected. From the results emulsified fuel having 5% water concentration, HLB: 6 and 2% surfactant were found to be the best optimum emulsified blend.
