Glycerine emulsions of diesel-biodiesel blends and their performance and emissions in a diesel engine

Emulsion stability, mean particle droplet size, fuel properties, engine performance, and emissions were examined. Test results show that with the increase in glycerine concentration, brake-specific fuel consumption and brake-thermal efficiency increased. In terms of emissions, it was seen that carbon monoxide and unburned hydrocarbon increased, and reductions in exhaust gas temperature and oxides of nitrogen were observed. In addition, there was a significant decrease in smoke (approximately 80%) with an increased concentration of glycerine at 3000 rpm, at high load.
