TL;DR: In this article, an experimental investigation was conducted in a single cylinder constant speed diesel engine to establish the effects of Carbon Nanotubes (CNT) with the Jatropha Methyl Esters (JME) emulsion fuel.
Abstract: An experimental investigation was conducted in a single cylinder constant speed diesel engine to establish the effects of Carbon Nanotubes (CNT) with the Jatropha Methyl Esters (JME) emulsion fuel. The JME was produced from the Jatropha oil by transesterification process, and subsequently the JME emulsion fuel was prepared in the proportion of 93% of JME, 5% of water and 2% of surfactants (by volume) with a hydrophilic–lipophilic balance of 10. The Carbon Nanotubes are blended with the JME emulsion fuel in the various dosages systematically. The whole investigation was conducted in the diesel engine using the following fuels: neat JME, neat JME emulsion fuel and CNT blended JME emulsion fuels accordingly. The experimental results revealed an appreciable enhancement in the brake thermal efficiency for the CNT blended JME emulsion fuels compared to that of neat JME and neat JME emulsion fuel. At the full load, the brake thermal efficiency for the JME fuel observed was 24.80%, whereas it was 26.34% and 28.45% for the JME2S5W and JME2S5W100CNT fuels respectively. Further, due to the combined effects of micro-explosion and secondary atomization phenomena associated with the CNT blended JME emulsion fuels, the level of harmful pollutants in the exhaust gases (such as NOx and smoke) was drastically reduced when compared to that of neat JME. At the full load, the magnitude of NOx and smoke opacity for the neat JME was 1282 ppm and 69%, whereas it was 910 ppm and 49% for the JME2S5W100CNT fuel respectively.

TL;DR: In this article, the performance, emission, and combustion characteristics of a single cylinder Compression Ignition (CI) engine using water-diesel emulsion fuel, and the alumina nanoparticles blended with the water -diesel fuel in the mass fractions of 25, 50, and 100 ppm systematically.
Abstract: In this present work, the investigations are carried out to study the performance, emission, and combustion characteristics of a single cylinder Compression Ignition (CI) engine using water–diesel emulsion fuel, and the alumina nanoparticles blended water–diesel emulsion fuels. The water–diesel emulsion fuel is prepared by the emulsification method in the proportion of 83% diesel, 15% water, and 2% surfactants by volume. The alumina nanoparticles are blended with the water–diesel emulsion fuel in the mass fractions of 25, 50, and 100 ppm systematically. The experiments are conducted at a constant speed of 1500 rpm and the results revealed a substantial enhancement in the performance and reduction in the harmful pollutants due to the incorporation of alumina nanoparticles in the water–diesel emulsion fuel. Furthermore, the hot-plate evaporation characteristics test asserted a considerable reduction in the evaporation time by adding the potential alumina nanoparticles to the water–diesel emulsion fuel.

TL;DR: In this article, various combustion modes of water-in-oil emulsion droplets are postulated based on the relative volatilities and concentrations of water and oil, the intensity of internal circulation, and the fact that oil and water do not mix.

TL;DR: In this paper, a 4-cycle direct injection engine with water-fuel emulsion and non-ionic emulsifying agent was used to achieve a large reduction of NOx concentration.
Abstract: With the aid of static mixer and non-ionic emulsifying agent, a comparatively stable water-fuel emulsion was obtained. Engine performance in a 4 cycle direct injection engine using these fuels were studied. A large reduction of NOx concentration was obtained over the wide range of engine operations, in spite of increased ignition lag and rapid combustion. Furthermore, improvements of economy and reduction of exhaust smoke were obtained. The reduction of NOx concentration, fuel consumption and smoke were even more remarkable when compared with operating same engine with water fumigation.

Abstract: This paper describes an experiment in which water-in-gas oil emulsified fuel is used without high pressure or high injection rate to improve engine performance parameters such as smoke, NO/sub chi/, and BSFC in a DI diesel engine. The results are compared with high pressure and high injection rate operation using gas oil.
