Effective utilization of cashew nut shell pyro oil blended with optimum amount of Al2O3 and TiO2 nanoparticles in DI engine

Abstract

The present research activity's major objective is to improve the performance and emission characteristics of diesel engines that burn pyro oil and cashew nut shell nanoparticles. This work identifies the nanoparticles that should be added to cashew nut shell pyro oil to allow it to be utilized efficiently in compression ignition engines. In this experiment, the two nanoparticles, Al2O3 and TiO2, were mixed with cashew nut shell pyro oil. For testing purposes, nanoparticles were combined with cashew nut shell pyro oil at various concentrations, including 150 and 200 ppm. The criterion for picking the best combination was stability. To improve the optimal performance of the nanoparticle-blended oil, the cashew nut shell pyro oil was emulsified. The nanoparticles, which also act as an enhancing agent, speed up the combustion process. The combination of pyro oil, cashew nut shell emulsion, and nanoparticles improved performance and reduced emissions. The brake thermal efficiency values for 200 ppm Al2O3 and TiO2 mixed emulsified cashew nut shell pyro oil were 29.6% and 29.4%, respectively, whereas the values for diesel and cashew nut shell pyro oil were 31.6% and 29.8%. When comparing cashew nut shell pyro oil to oil with 200 ppm Al2O3 and TiO2, the smoke value was found to be reduced by 58.8% and 56.7%, respectively. It was discovered that cashew nutshell pyro oil with 200 ppm Al2O3 and TiO2 had 35.3% and 34.96% reduced hydrocarbon emissions respectively.
