The main objective of this study is to analyze the different ratio of emulsified fuels on the performance, emission and combustion characteristics of four stroke single cylinder kirloskar TV-I direct injection compression ignition engine and compared with diesel fuel under different engine loads with constant engine speed of 1500 rpm. Four kinds of test fuels were prepared namely 80% diesel, 10% ethanol and 10% surfactant (Identified as D80E10); 70% diesel, 20% ethanol and 10% surfactant (denoted as D70 E20); 60% diesel 30% ethanol and 10% surfactant (denoted as D60 E30); 50% diesel, 40% ethanol and 10% surfactant (denoted as D50 E40) by volume respectively. In this test, Benzal konium chloride is added as an emulsifier to the diesel-ethanol blend to prevent layer formation and to make it a homogeneous blend. At maximum brake power, the comparison of best emulsified fuel ratio with diesel fuel results showed improvement in brake thermal efficiency with decrease in specific fuel consumption and smoke. The NOX, HC, CO2, cylinder pressure and heat release rate for D50 E40 emulsions are higher when compared to diesel fuel.
