Abstract :
In this paper four new emulsions were prepared by mixing 10% water, 0.5% tween 20 and 0.5% span 20
with diesel fuel using different aqueous metal salts, the performance and emission tests were carried out by using the
fuel in a single cylinder water cooled diesel engine. The results were compared with that of diesel and comparison
graphs were plotted to analyze the advantages and disadvantages of using the new emulsions over diesel. This report
analyze on the effect of new emulsion fuels combustion on brake thermal efficiency, brake specific fuel consumption,
oxides of nitrogen and hydrocarbon emissions. The emulsions used for analysis achieved reasonable reductions in
the NOx emission from diesel engines without requiring any retrofitting of the engines and also there was no notable
increase in emission of other pollutants.
