Abstract
The current research work focuses mainly on improving the performance and emission characteristics of nanoparticle-blended mahua oil-fueled diesel engine. This work concentrates on finding the optimum quantity of nanoparticles to be blended with mahua oil so that it can be effectively deployed in compression ignition (CI) engine. A 4-stroke diesel engine with 3.7kW at 1500rpm was employed in this research. The two nanoparticles, Al2O3 and TiO2, were used in this experiment to blend with mahua oil. The nanoparticles of different concentrations, such as 25, 50, 75, and 100ppm, were blended with mahua oil to test the performance. Based on the stability, the optimum blend was chosen. The mahua oil was emulsified in order to further enhance the optimum performance of the nanoparticle-blended mahua oil. The nanoparticles act as a combustion enhancer and aggravate the combustion process. The nanoparticle-blended emulsified mahua oil showed better performance and reduced emissions. The brake thermal efficiency (BTE) values of 100ppm Al2O3 and TiO2 blended emulsified mahua oil (EMO) were 29.2% and 28.4% respectively, while in case of diesel and mahua oil, the values were 31.4% and 23.8% respectively. The smoke value for EMO with 100ppm Al2O3 and TiO2 was found to have decreased by 61.9% and 59.4% respectively compared with mahua oil. The hydrocarbon (HC) emissions for EMO with 100ppm Al2O3 and TiO2 were found to have decreased by 37.3% and 32.96% respectively.
