Urban air pollution is primarily attributed to the use of gas oline-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 the synthesis of 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 gas oline was evaluated in a 150 cc motorcycle under various loads (1.2 Nm, 6.2 Nm, 11.2 Nm) and speeds (570 rpm , 850 rpm , 1044 rpm, 1269 rpm, 1427 rpm) to assess fuel exergy efficiency and net work exergy input. At a pressure of 11.2 Nm and a speed of 1427 rpm -1269 rpm, engine shutdown occurred across all fuel injections due to excessive pressure and inadequate thermal capacity of the fuel. The findings indicated that the addition of triple compounds to gasoline fuel enhanced the braking power exergy due to the high density of these compounds.
