An Investigation of Diesel-Ethanol-Biodiesel Blends for Diesel Engine: Part 1. Emulsion Stability and Fuel Properties

Diesohol, a blend of regular diesel and ethanol, is one of the potential alternative fuels to reduce the use of regular diesel. In the present study, biodiesel offers its alternative application as an emulsifier for diesohol blends, in which both hydrous and anhydrous alcohols were blended with regular diesel at different compositions. The emulsification tests were initially conducted to obtain homogeneous diesohol emulsion. The selected blends with different compositions were tested for physical and chemical properties to meet the diesel fuel requirements. The results show that only the blend of 84.00% (vol.) diesel, 0.25% hydrous ethanol, 4.75% anhydrous ethanol, and 11.00% biodiesel can meet the requirements of standard diesel.
