To investigate the waste-derived ethylene glycol diacetate using the blends of karanja and jatropha biodiesels

Abstract

The purpose of this study was to introduce and test a new wastederived oxygenated additive ethylene glycol diacetate on the performance and emission characteristics of a diesel engine running on dieselbiodiesel blends The engine performance and exhaust emissions of a diesel engine were studied using Karanja and Jatropha blends with ethylene glycol diacetate additive in appropriate volume proportions 5 percent 10 and 15 When compared to diesel fuel characterisation data revealed that jatropha and karanja have a higher calorific value a higher flash point and a worse coldflow plugging point Ethylene glycol diacetate was added to these gasoline mixes at three different volumetric amounts ranging from 1 to 3 percentUnder moderate engine load circumstances the most appealing results were obtained when diesel fuel dosed with 3 vol percent ethylene glycol diacetate was combusted In comparison to additivefree diesel fuel this oxygenated fuel blend could result in significant reductions in nitrogen oxides and carbon dioxide emissions but it could also result in an unfavourable rise in unburned hydrocarbon emissions The purpose of adding DEE as an addition to KMEdiesel blends is to improve the DEE blended biodiesels combustion properties and emission patternThis fuel combination produced carbon monoxide emissions that were comparable to that of straight diesel Furthermore the considerable reductions in nitrogen oxide and carbon dioxide emissions were achieved with only a 5 reduction in the engines braking thermal efficiency Finally the discovered oxygenated additive could be utilised to reformulate diesel fuel in order to significantly reduce nitrogen oxide emissions
