The engine experiments contucted of two stages. Firstly, it was attempted to determine the maximum amount of fusel oil that could be added to diesel fuel. The blends obtained to this end were tested in a diesel engine, and it was observed that there was a maximum rate of 37% that would work without any problems. After blending 63% diesel and 37% fusel oil, the test engine does not run if the fusel oil ratio in fuel blends is increased. Afterward, experiments were performed at different engine speeds (1250–3000 rpm) in the full load conditions with the fuel blends created (D100, F5, F10, F20, F30, and F37). Additionally, exergy, energy, and exorgoeconomic analyses were carried out using engine performance and exhaust emission values acquired in experimental studies. It was stated that addition of fusel oil to fuel blends increased fuel consumption. If the engine ran at a speed of 2250 rpm, there was 17% more fuel consumption in F37 fuel than D100 fuel. In fuel blends using fusel oil, NOX, CO2, and soot emissions are lower in comparison with D100 fuel. In this research, it was observed that the addition of fusel oil to diesel exhibited a significant decrease in NOX and CO2 emissions but created a significant increase in particulate matter, CO and HC emissions. A parallel increase occurred in exergy losses in engine due to increase in fusel oil in blends. The highest exergy destruction was calculated as 22 kW in F37 fuel at 3250 rpm. As the ratio of fusel oil in fuel blends increases, the useful power cost and the cost of CO2 released into the atmosphere decrease.
