Abstract: newlineThe present study focuses on identifying the optimum diesel- dual biodiesel blend from newlinethe available eight biodiesel. TOPSIS and PROMETHEE methods based on multiple criteria newlinedecision-making techniques are selected to identify the best dual biodiesel-diesel blend. The newlineengine performance, combustion and emission are chosen as criteria for the decision making. newlineThe brake-specific fuel consumption and thermal efficiency are the key parameters to determine newlineengine performance. Similarly, the peak in-cylinder pressure and the delay period characterize newlinecombustion, while the emission is defined by the emissions measured for Nitrogen oxide (ppm), newlineHydrocarbon (ppm), Smoke opacity (%). The entire study is carried out in two steps to newlineminimize the experiments. The implementation of two different decision-making methods with newlinevarious parameters guarantees that the solution is similar to the ideal solution. The newline70D15CA15R (70% Diesel, 15% Castor and 15% Rapeseed) is obtained as an optimum blend newlinein reference to all engine performance. newlineThe second part of the study focuses on identifying the optimum percentage of water to newlinebe added for preparing a stable emulsified fuel blend and the possibility of reducing engine newlineemission (NOx and HC) using 70D15CA15R as the base fuel. This optimum blend has been newlineused for the preparation of W/O emulsified fuel. In emulsified fuel, water percentages varied newlinefrom 1 to 5%, 10%, and different emulsified fuel blends were prepared based on HLB ratios newlineranging from 4.3, 5 and 6. The results of the first and second phases of the experiments show newlinethat the addition of 5 v/v % water seems to be a more stable blend than the addition of 1, 2, 3, newline4 and 10 v/v % water. The experiments were carried out on a VCR, single-cylinder, four-stroke, newlinewater-cooled diesel engine operated under varying load conditions 0 to 110% at constant newlineoperating speed (1500 rpm) with injection time 20° BTDC. Based upon the engine performance, newlinecombustion, and emission analysis, the best optimum emulsified fuel has been selected. F
