Research Objectives. In this modern era increase in Pollution became a huge impact in the lives of all living creatures, in this automobile tends to be one of the major contributors in terms of air pollution thanks to their exhaust emissions. The objective of the present study is to reduce the amount of harmful pollutants emitted from the automobiles by the utilization of a biofuel further influenced by two additives (liquid and a Nano additive). Methodology In this study, first the bio oil is extracted, Then the biofuel is mixed with diesel fuel at different proportions of 20%, 40% by volume. Experiments are carried out in a direct injection compression ignition engine, which is a stationary test engine manufactured by Kirloskar, connected to a computer setup. The emission values in the exhaust gases are obtained using AVL exhaust gas analyzer. Then 0.1% of rice husk nano additive is added with the fuel blend followed by 3%, 6% of 1,4-Dioxane blended with the previous blend and its performance (BTE, BSFC) and emission (HC, CO, CO2, NOx, Smoke) values are tested. The values are tabulated and compared for identifying the best blends of them all in terms of emission reduction. Results Performance of the engine reduced with the addition of the additives for about 4.3% compared with that of diesel fuel. And also, considerable reduction in emission was noticed for HC, CO, Smoke and even for NOx emission with the increase in 1,4-dioxane percentage. the addition of rice husk nano particles aids in emission reduction process. The 40% blend along with 6% and 0.1% of 1,4-dioxane and rice husk shows the lowest possible emission. Limitations of this study Addition of 1,4-dioxane aids in reducing NOx emission, which is one of the more harmful pollutant but on the contrary it also reduces performance parameters, which is an essential term for most of the consumers. What does the paper offer that is new in the field including in comparison to other work by the authors? The analysis of biodiesel blend's characteristics and comparing them with that of the blends added with additives of 1,4-dioxane and Rice Husk Nano particle is a new one. Conclusions This comparison analysis helps in understanding the influence of the additives on the biodiesel blends. And also the outcome is used to determine the suitability of the combination considered here for use in vehicles without any major modifications.
