The present experiment was conducted by executing detailed tests on performance, combustion, and emission characteristics to prove that the Nerium biodiesel emulsified fuel can be an eco-friendly fuel. The emulsified biodiesel was formed by mixing with a small proportion of water in the limits of 5%, 10%, and 15% by volume. This study also assessed the stability of different emulsified blends. The properties were tested according to ASTM requirements. The blend of 60% diesel, 20% biodiesel, 15% water, and 5% surfactant showed the higher brake thermal efficiency and in-cylinder pressure by 13.72% and 12.6%, respectively, when related to base fuel. Also, carbon monoxide, oxides of nitrogen, opacity of smoke and hydrocarbon emission of the above blend decreased by 42.87%, 6.5%, 12.96%, and 31.94%, respectively, when related to base fuel. This can be attributed due to the micro-explosion and availability of the oxygen content in the fuel. The results noticed a significant improvement and advantage of using the eco-friendly emulsified fuel in traditional engines without any modifications. Micro-explosion during combustion stage guaranteed a reduction in emission of nitrogen oxides (NOx). [ABSTRACT FROM AUTHOR] |
