Application of Ethanol/Diesel Blend as a Fuel for Diesel Engines

The exhaust emission pollutants of diesel engines include particulate matters (PM), smoke, oxides of nitrogen (NOx), and other harmful compounds. Ethanol diesel blend (e-diesel) is a clean-burning alternative to regular diesel fuel. The easiest method by which ethanol can be used is in the form of solutions, but ethanol has limited solubility in diesel. The problem of limited solubility has been overcome by emulsions. In this paper, with the use of environmentally friendly additives, the preparation of stable and clear nanoemulsions is investigated. The comparison of engine performance of ethanol-diesel emulsions and standard diesel in OM314 engine showed a reduction of 7.5% and 17.2% in power and smoke respectively. The use of ethanol-diesel fuels had no detrimental effect on the fuel system and engine components of OM314 engine.
