| Abstract | Biodiesel resembles the qualities of fossil diesel while it is also proven to be a greener fuel and viable alternative. However, the primary challenge of using biodiesel was higher emissions of Nitrogen oxides (NOx). Hence to minimize the NOx, an exhaust gas re-circulation (EGR) system could be utilized and could resolve the challenges associated with this higher NOx emissions. In this study, dairy waste scum oil biodiesel was prepared and blended with diesel at 20% by volume (B20) and three different EGR percentages 5%, 10%, and 15%, were investigated on the characteristics of CI engine. Based on the test outcomes, a drop in NOx has been observed with a 15% rate of EGR which is 6.1% lower than conventional diesel. Moreover, brake thermal efficiency increased by 11% as compared to diesel. However, a slight increase in other exhaust emissions was noticed with EGR. The findings indicate that utilizing a lower rate of exhaust gas re-circulation (EGR) at 15 % in conjunction with a B20 blend of dairy waste scum oil biodiesel yields optimal engine performance while minimizing NOx emissions. |
