Abstract: In this study, thermodynamic and economic analyses were performed by evaluating performance data obtained by operating diesel, biodiesel, and alcohol blends. The highest energy and exergy efficiencies were computed for B20Hx10 at full load. The maximum entropy production was found at full load for B20Pe30. Similar to efficiencies, exergoeconomic data were also greatly influenced by the increase in the load. Besides that, the increase in the rate of higher alcohol negatively affected fuel costs. To conclude, the crankshaft work cost flow rate was $1.27/h for D100, $1.73/h for B20, and $5.86/h for B20Hx10 at the lowest load.

Keywords: diesel engine; higher alcohol; thermodynamic; exergoeconomic.
