A Comparative Study of Performance and Emission Characteristics of Biodiesel Blends with Diethylene Glycol Dimethyl Ether as Additive

Abstract

An experimental investigation was carried out to analyze the performance and emission characteristics of a compression ignition engine fueled with 20% biodiesel and 80% conventional diesel blended with diethylene glycol dimethyl ether on volume basis (0.2 to 0.6%). The performance test includes brake thermal efficiency and fuel consumption. The exhaust emission includes smoke density, CO, HC, CO₂, and NO_x. These parameters are evaluated in a single-cylinder diesel engine coupled with an eddy current dynamometer. The above factors in each case were compared with baseline data of mineral diesel and significant improvements have been observed.
