Abstract
Urban air pollution is primarily attributed to using gasoline-fueled cars with internal combustion engines, leading to a depletion of fossil fuel reserves, increased pollution from combustion, and respiratory illnesses. One approach to mitigate combustion-related pollutants is the incorporation of biofuel-based additives. Glycerin, a byproduct of biodiesel production, plays a crucial role in synthesizing these additives. This study focuses on converting glycerin derived from sunflower oil into Solketal-acetin, a novel biofuel blend with gasoline. This unique fuel blend exhibited favorable characteristics at specific composition ratios. The performance of the Solketal-acetin additive blend with gasoline was evaluated in a 150 cc motorcycle under various loads (1/2, 6/2, 11/2 Nm) and speeds (570, 850, 1044, 1269, 1427rpm) to assess fuel exergy efficiency and net-work exergy input. At a load of 11/2 Nm and a speed of 1427-1269 rpm, engine shutdown occurred across all fuel injections due to excessive load and inadequate thermal capacity of the fuel. The findings indicated that adding triple compounds to gasoline fuel enhanced the braking power exergy due to the high density of these compounds.
