Study of the Performance and Emissions of the Compression-Ignition (CI) Engine Using Ethyl Acetate as a Surfactant in Ethanol-Based Emulsified Fuel

In this research work, emulsified fuel has been prepared with the help of ethyl acetate as a surfactant and its performance and emission characteristics have been compared to diesel fuel number 2. The best emulsified fuel ratio [50% diesel and 50% ethanol (50D/50E), 100% proof] has been used in this work. A water-in-oil-type emulsion method has been used in the preparation of the emulsified fuel. It has been tested with a four-stroke, water-cooled, single-cylinder, compression-ignition (Cl) diesel engine. The entire experiment has been carried out at a constant speed of 1500 revolutions/min. In comparison to diesel fuel, emulsified fuel is found to increase brake thermal efficiency and oxides of nitrogen and decrease specific fuel consumption, particulate matter, hydrocarbons, and carbon monoxide.
