Performance and emission characteristics of salviniaceae filiculoides aquatic fern oil and SiO2 nano additive biodiesel in CI engine

Abstract

This present study deals the engine performance and emission of adding SiO2 nano additives in novel salviniaceae filiculoides aquatic fern biomass derived biodiesel. The primary aim of this present study was to investigate the effect of adding SiO2 nano additives into the Azolla Oil Methyl Ester (AZOME) as a sustainable biodiesel in the Compression Ignition (CI) engine and studying the engine performance and emission effects. The Azolla Oil Methyl Ester was prepared via transesterification process and blended with as-present diesel with various percentages. The SiO2 nano particles are mixed with AZOME using sonication. The test was conducted using a single cylinder Compression Ignition engine with different blends of AZOME biodiesel. The fuel was injected into the engine at different spill timings as 20°, 23°, and 26° Crank Angle (CA) before (b) Top Dead Centre (TDC). According to the results the break thermal efficiency of AZOME and its SiO2 blends were improved with spill timings. On compare with the conventional diesel the Injection Time (IT) of 23° b TDC and the average Brake Thermal Efficiency (BTE) of AZ20 fuel at the retarded spill timing of 20° was raised by 3.38%, while the AZ100 fuel at 20° b TDC is decreased by 0.9%. However the emission of AZ100 fuel found to be lesser due to the presence of SiO2 nano additives. Thus the addition of SiO2 nano additives along with aquatic biomass Azolla Oil Methyl Ester reduced the emission without affecting the engine performance.
