In this study, Four different ratio of emulsified fuels are used as alternative fuels for four stroke, single cylinder, water cooled, naturally aspirated direct injection diesel engine to analyze the performance, emission and combustion characteristics, namely Specific Fuel Consumption (SFC), Brake Thermal Efficiency (BTE), Hydrocarbon (HC), Nitrogen Oxides (NOx), smoke, cylinder pressure and heat release rate and compared with diesel fuel under different load conditions with constant engine speed of 1500 rpm. The blends prepared were D80E10 (80% Diesel and 10% Ethanol), D70E20, D60E30 and D50E40 with the addition of 10% surfactant in each blend on volume basis. At full load, compared to diesel fuel, the experimental results of D50E40 blend showed 3.06% reduction in SFC, 21.3% improvement in BTE, 37.08% increase in HC, 31.1% increase in NOx and 42.3% reduction in smoke. The cylinder pressure and heat release rate of D50E40 blends is higher with increasing ethanol percentage in the blend.
