|Effects of Cerium Oxide Nanoparticle on Compression Ignintion Engine Performance and Emission When Using Water Diesel Emulsion
|Alternative fuel;Nanofulid;mechanical engineering
|The main reason for using alternative fuels in compression ignition engine is that the consumption and demand of petroleum products are increasing every year due to urbanization, increase in vehicular density and power requirement is going up and to reduce emission produced by today’s diesel engine, which in turns require a clean burning fuel that perform well under the variety of operating conditions. Using an emulsion of diesel in water as a fuel has been a recent field of study in this field. Water/diesel (W/D) emulsified formulations are reported to reduce the emissions without compensating the engine’s performance. In present work an emulsion was prepared by adding nanoparticle as a fuel additive. A detailed experiment study has been conducted to evaluate the effect of cerium oxide dose level in 15% water emulsion diesel. The emulsification method was used to produce E15.The span 80 and tween 80 were used as surfactants. The cerium oxide nanoparticle dose level in water emulsion diesel were 40, 60, 80 ppm respectively. The experiments were performed in a 4-cylinder, 4-stroke water cooled diesel engine at constant 1650 RPM, over different load condition. The properties such as viscosity, flash point, and calorific value were also determined as per standards. Experiments were conducted using diesel and different blends of emulsion such as E15, E15CeO240, E15CeO260, and E15CeO280 by varying the load on engine. Performance and emission parameter of different blends of emulsion were compared to pure diesel. Results reported that cerium oxide blended fuels substantially improve the performance and reduce harmful pollutants.
