Experimental investigation on SiO2 nano particle as additives on performance and emission parameters of diesel engine fueled with castor oil blends

Abstract

Introduction: Today, a lot of research work is carried out in the vegetable oil based fuels which are the blended renewable fuels derived from vegetable oils or the oxygenated fuels which could effect in reduced Carbonaceous emissions. This experimental study investigates the impact of Silicon dioxide (SiO2) nanoparticles as additives on the performance and emission parameters of a diesel engine running on castor oil blends.
Materials and methods: Castor oil is a renewable source of biodiesel, but it has limitations such as lower calorific value and higher viscosity compared to conventional diesel. To overcome these limitations, SiO2 nanoparticles were synthesized and characterized. Tests were conducted on a single-cylinder diesel engine under various load conditions using different fuel blends.
Results: Results shows that the addition of SiO2 nanoparticles improved the engine's performance by increasing brake thermal efficiency by 25% and reducing specific fuel consumption by 9%. Carbon monoxide emissions (CO) were decreased by 25%, Hydro Carbon emissions (HC) decreased by 52% with SiO2 nanoparticles while a marginal percentage of NOx was also observed.
Conclusion: This study demonstrates the potential of SiO2 nanoparticles as additives in enhancing the performance and reducing emissions of diesel engines using castor oil blends, contributing to the development of sustainable transportation.
