Özet

In this study, performance and emission values were obtained under full load by using ethanol-gasoline blends as a fuel at different rates in a spark-ignition engine, and exergy, exergoeconomic and environmental analyses were performed with these values. Exergy of a fuel entering engine and lost exergies through cooling system, exhaust and radiation were calculated. CO, CO2, HC, and NO(X)emissions released from engine into environment were measured, and according to environmental analysis, cost of CO(2)emission was calculated as 393.78 USD/year for E0 fuel and as 306.78 USD/year for E30 fuel at 2,000 rpm. Ethanol-gasoline blends at different rates, environmental damage can be reduced by around 30% on an annual basis. Furthermore, with environmental analysis, lowest engine output power cost was found to be 29.77 USD/MJ in E0 fuel at 2,000 rpm, while highest engine output power cost was found to be 120 USD/MJ in E30 fuel at 4,500 rpm.
