An Experimental Study of Fuel Properties of Diesel Blends With Sunflower/Soybean Oil and Ethanol

Abstract

Biodiesel, a renewable alternative fuel manufactured by transesterifying vegetable oil with ethanol, is becoming more widely available for use in transportation blends with traditional diesel fuel. The higher density and viscosity of these biodiesel mixes than diesel is a substantial hurdle to commercial biodiesel use. Varied fuel sources, such as sunflower oil and soybean oil, were used to make biodiesel in various amounts in this study. The effects of different biodiesel mix concentrations on efficiency, NOx, CO, and smoke opacity characteristics were studied experimentally. The addition of ethanol to balm/sunflower oil biodiesel improves efficiency due to the good combustion process, according to the findings. For all load circumstances, the Su5Sb5D85E10 bio diesel performed better with reduced emissions. Overall, adding ethanol to soybean/biodiesel fuel reduced emissions of NOx, CO, and smoke opacity. The findings indicate to a method for improving diesel fuel performance in terms of environmental effect.
