Combustion, performance, and emission analysis of diesel engine fueled with water-biodiesel emulsion fuel and nanoadditive. Environ Sci Pollut Res Int. 2018 Sep 28;: Authors: Vellaiyan S, Subbiah A, Chockalingam P Abstract The present study is aimed to analyze the combustion, performance, and emission characteristics of water-emulsified soybean biodiesel fueled diesel engine with alumina nanoadditive and the results compared with conventional diesel fuel (BD). Experiments were conducted in a single-cylinder, four-stroke, variable compression ratio, and natural aspirated diesel engine with an eddy current dynamometer at a constant speed of 1500 rpm. Water-soybean biodiesel emulsion fuel was prepared using a mechanical agitator, in which the water concentration was limited to 10%, whereas soybean biodiesel (SB) and surfactant concentrations were 89% and 1% by volume respectively. Alumina (Al) was chosen as a nanoadditive, and the mass fractions of 50 ppm and 100 ppm were blended with emulsion fuel using ultrasonicator and the physicochemical properties were measured. The physicochemical properties of water-emulsified biodiesel and nanoadditive included emulsified biodiesel are at par with EN14214 limits. The in-cylinder pressure (ICP) and net heat release rate (NHR) values of SB are 5.3% and 7.2% lower than BD respectively, whereas the water inclusion significantly increases the ICP and NHR values by 6.9% and 15.9% compared to SB.
