Abstract

Although fossil fuel reserves have been decreasing day by day, the high carbon emissions of fossil-based vehicles and the fact that these carbon emissions trigger global warming cau-se researchers to focus on alternative fuels. CO and HC, which form the exhaust emissions of motor vehicles, called unburned fuel, have been, threatened human health. Efforts to re-duce CO2, which triggers global warming, and NOx emissions, which turn into acid rain, are increasing day by day. It is tried to reduce harmful exhaust emissions by mixing ethanol, methanol, propanol, butanol and their derivatives fuels as alcohol-based fuels in motor fuels in certain proportions. The aim of this study is to investigate the usability of waste fusel oil and plant-based methanol as an alternative fuel in internal combustion engines without the need for any auxiliary system and investigate the effects of fusel oil and methanol fuels added to gasoline on engine performance and emissions. In the experimental study, as engi-ne performance, it was determined that the engine torque decreased by 11.62% in F20 fuel and 6.45% in M20 fuel compared to G fuel.While an increase in BSFC values was detected in both test fuels, there was a decrease in EGT values.According to the emission results, an average decrease of 7.31% in F20 fuel and 13.40% in M20 fuel was detected in CO values compared to G fuel, while an increase in CO2 and NOx values occurred.
