“…The Diesel fuel emulsion is then utilized in the CI engine as normal. The use of Diesel fuel emulsions has been shown to reduce NO x , CO, soot, hydrocarbons (HC) and PM emissions when used in a CI engine [3][4][5][6][7][8][9][10]. Diesel fuel emulsions have also been shown to slightly improve the brake thermal efficiency of a CI engine [8,[10][11][12].…”

h i g h l i g h t sFuel injection sprays have been examined using a focused shadowgraph system. Diesel and Diesel and water emulsions containing 10% and 20% water examined. Temporal evolution of the spray cone angle and tip penetration have been measured. Emulsification reduced the cone angle at injection pressure of 500 bar. Emulsification had no discernable influence on the tip penetration. t r a c tDiesel fuel and water emulsions have been shown to reduce emissions of NO x and PM from compression ignition engines. There is a lack of work examining the influence of emulsification on the sprays formed during injection. This work examines the spray cone angle and tip penetration of Diesel fuel and water emulsions, containing 10% and 20% water (by mass). All experiments were conducted under nonreacting, non-vaporizing conditions in a constant volume pressure chamber filled with nitrogen. A focused shadowgraph system, with high speed photography, coupled with a research, high current LED system was used. Differences in the spray cone angle suggest the emulsification did have an effect for the injections at a pressure of 500 bar. Emulsification had no discernible effect on the spray tip penetration. Spray tip penetration showed agreement with previous trends in terms of proportionality to time after start of injection however agreement with models found in the literature was not consistent.

“…It is a high-energy method of formulation nanoemulsions that is able to decrease the size of droplets in the emulsion, which can promote very small droplet diameter, high physical stability, high bioavailability, and optical transparency. 22,23 Because of the small size of the droplets, gravitational separation, flocculation, and coalescence often occur at a reduced rate in nanoemulsions. Nanoemulsion presents a very interesting application in certain food and beverage since the small droplet size promotes transparency or only slightly turbid in the food product.…”

“…(2010). In addition, Lin and Chen (2008) reported that the high-speed mechanical homogenization emulsification method has an optimal effect over ultrasonic and supersonic vibrations as far as smoke and NOx emissions are concerned. Thus, sorbitan monolaurate (a nonionic surfactant of HLB 8.6) and high-speed mechanical agitator (5000 rpm) were employed in the present study.…”

The use of water-in-diesel (W/D) emulsion fuel has the potential to promote better performance with lower emissions in existing diesel engines. The present study aims to analyzes the influence of operating parameters on the overall engine performance and emission characteristics using W/D emulsion fuel and to obtain the optimum level for favorable performance and emission levels. The engine operating parameters were optimized using a Taguchi-grey relation based multi-response optimization tool. Two controlling parameters, namely compression ratio (CR) and percentage of W/D, were considered as input process parameters. An L16 orthogonal array was used to collect the output responses (performance and emissions) under varying engine load conditions. The signal-to-noise (S/N) ratio and grey relational analysis were used to analyze the performance and emission parameters. From the results obtained, it is noted that both controlling parameters have a significant effect on the performance and emission levels. The optimum level of performance and emission levels are obtained at a CR of 18 and water concentration of 10%. Moreover, under these optimum conditions, i.e. at 10% of water concentration, the fuel properties are at par with the standard diesel fuel properties requirement.
