An Experimental Study in a CI Engine Using Nanoadditive Blended Water–Diesel Emulsion Fuel

In this present work, the investigations are carried out to study the performance, emission, and combustion characteristics of a single cylinder Compression Ignition (CI) engine using water–diesel emulsion fuel, and the alumina nanoparticles blended water–diesel emulsion fuels. The water–diesel emulsion fuel is prepared by the emulsification method in the proportion of 83% diesel, 15% water, and 2% surfactants by volume. The alumina nanoparticles are blended with the water–diesel emulsion fuel in the mass fractions of 25, 50, and 100 ppm systematically. The experiments are conducted at a constant speed of 1500 rpm and the results revealed a substantial enhancement in the performance and reduction in the harmful pollutants due to the incorporation of alumina nanoparticles in the water–diesel emulsion fuel. Furthermore, the hot-plate evaporation characteristics test asserted a considerable reduction in the evaporation time by adding the potential alumina nanoparticles to the water–diesel emulsion fuel.
