Experimental Investigation on Diesel Engine Using Dual Biodiesel Blends

Abstract

The globe is facing energy demand issues, rising petroleum newlineprices, and a scarcity of fossil fuel supplies. Biodiesel is made from newlinevegetable oils and is seen as a viable alternative fuel. Because of its newlineenhanced availability, edible oil is used as a biodiesel at a higher rate than newlinenon-edible oils. The use of a significant number of edible oils as biodiesel newlinemay result in food depletion, limited availability, and economic concerns. newlineThere have already been studies on diesel blends and single newlinebiodiesels. Very few studies have been conducted using the combination newlineof two distinct biodiesel mixes with diesel, leaving a lot of scope for newlinefuture research. The current study conducts an experiment using two newlinebiodiesels derived from candle nut oil and soap nut, which are blended newlinewith diesel at different mixing ratios [0%, 10%, 20%, 30%, 40%, 50%, newline60%, 70%, 80%, 90%, 100% by volume]. The presence of paraffinic, newlinenaphthenic, and aromatic hydrocarbons lead to increase in the cold filter newlineplugging point of soapnut biodiesel. By combining the two fuels, the newlinelower oxidation stability of candlenut biodiesel and the higher cold filter newlineplugging point of soap nut oil biodiesel were enhanced. newlineThe major goal of this work was to optimize the blending newlineparameters of Soapnut biodiesel and Candlenut biodiesel, particularly the newlinecold filter plugging point and oxidation stability, and to operate the engine newlinewith no changes to achieve the lowest emissions. The effects of optimum newlinecombined biodiesel [40% candle nut and 60% Soap nut biodiesel] work newlineon engine and exhaust pollutants were investigated in a single-cylinder, newlinevi newlinedirect injection, air-cooled, high-speed diesel engine at varying engine newlineloads at a constant engine speed of 1500 rpm. newlineEmission tests were used to study the effects of various newlinecompositions of Biodiesel on CO, HC, NOx, and smoke opacity. The newlineBTE of blend optimum combined Biodiesel (40% Candle nut and 60% newlineSoap nut) and then mixed with Nanoparticles SiO2, Al2O3 and TiO2 were newlinetested in the engine.
