Investigation Of Performance Of A Diesel Engine Fuelled With Copper Oxide Nanoparticle Dispersed Azadirachta Indica Biodiesel Using Both Experimental And Theoretical Investigation

Abstract

Biodiesel has recently gained substantial interest in the realm of diesel newlineengines due to its capacity to greatly enhance combustion performance and decrease newlineemissions in compression ignition engines. An effective approach to enhance the newlinephysicochemical properties of biodiesel, optimize engine efficiency, and minimize newlineemissions is by using nanoparticles. However, there are additional challenges that newlinemust be addressed through thorough research and development in order to make newlinethese fuel mixtures a practical and environmentally advantageous choice for newlinecompression-ignition engines. The issues encompass dispersion, engine newlinecompatibility, and cost efficiency. newlineIn this work we analysed the stability and physicochemical properties of newlinecopper oxide (CuO) nanoparticles dispersed in an Azadirachta indica oil biodiesel newlinemixture (B20). The CuO nanoparticles were prepared at a concentration of 75ppm newlineand the dispersants were added in the same ratio as the CuO nanoparticles. newlineTRITONX75, QPAN75 and TWEEN75 were used as dispersants. newlineAn ultrasonic bath was used to sonicate the nanoparticles and produce the newlinenanofuel. In addition, an ultraviolet photospectrometer was used for stability analysis newlineof absorption and transmission. The stability analysis was carried out over a period of newlinethree weeks. The stability of the CuO nanoparticles in B20 increased compared to the newlinebase nanoparticles when the dispersants were added. However, higher absorption and newlinelower permeability were observed in the nanofuels spiked with QPAN compared to newlinethe other samples. In addition, the stability of all nanofuel samples decreased slightly newlineat the end of week 3. For the B20 +CuO75+QPAN75 nanofuel, higher absorption and newlinelower transmission values were obtained: 4.08 and 86.09% (week 1), 4.06 and newline88.03% (week 2) and 4.04 and 92.03% (week 3), respectively. In addition, the newline
