【 摘 要 】

Emulsions of fuels with water are effective in reducing NOx and particulatematter from diesel engines without any modifications in engine. So considering this as anobjective emulsions of water in oil (W/O) type were prepared by taking pure lemon oilwhich is a non-edible bio-oil as base fuel and water with varying percentages in range of 5-10% with two different emulsifiers span 80 and a new emulsifier Methyldihydroxypropylimidazolium chloride having HLB value around 8 with varying quantitiesby volume. Then the investigations on their stability was done. Electromagnetic stirrer andultrasonic technique of emulsification was used to prepare the emulsions. Totally eightsamples were prepared out of which four samples were prepared with 5% water andremaining four were prepared with 10% water with varying emulsifier & its percentages.The sample with 1.5% of span 80 with 5% water by volume showed good stability withemulsified layer retaining up to approx. 65% and the sample with combined emulsifiers span80 and Methyl-dihydroxypropylimidazoliumchloride for 5 % water also showed goodemulsion stability up to 60% even after 7 days & from the 10% water the sample withcombined surfactants span 80 2% and Methyl-dihydroxypropylimidazolium chloride 2% byvolume retained its stability up to 60%. The emulsion stability was evaluated based ongravitational or stand still method where the emulsions were kept stand still for 7 days andthe separation of layers was measured using measuring cylinders. The sample whichexhibited less separation was considered as stable. To assist or validate our stand still methodviscosity measurement of test samples was done at interval of each day for seven days usingcapillary viscometer. Then only stable emulsions samples with 5% water were tested forperformance and emissions on single cylinder four stroke water cooled diesel engine in termsof brake power, brake thermal efficiency, brake specific fuel consumption and emissions ofCO, HC, NOx. The results indicated that compared to pure lemon oil the brake thermalefficiency increased because of micro-explosion phenomenon of water and brake specificfuel consumption was increased. NOx emissions reduced but the HC & CO emissionincreased due to decreased calorific value of fuel because of addition of water.
