Özet
In this study, the exergy, exergoeconomic, enviroeconomic, and sustainability index analyzes of blends of biodiesel and diesel obtained from waste animal fats were examined. Within the scope of this study, the engine used in the experimental study has the features of a 3000-rpm fixed-speed four-stroke, single-cylinder, and air-cooled compression ignition engine. In addition, seven different fuels (D100 (0% Biodiesel + 100% Diesel), D90B10 (90% Diesel + 10% Animal Biodiesel), D80B20 (80% Diesel + 20% Animal Biodiesel), D70B30 (70% Diesel + 30% Animal Biodiesel), D50B50 (50% Diesel + 50% Animal Biodiesel), D25B75 (25% Diesel + 75% Animal Biodiesel), B100 (0% Diesel + 100% Animal Biodiesel)) were used in this study. The experiments were performed by loading the engine at 500 W intervals between 500 and 3000 W. As a result, the highest exergy efficiency was 24.86%, and obtained in D90B10 fuel at a 3000 W engine load. The lowest relative cost difference was 2.04, and obtained in D90B10 fuel at 3000 W engine load. The maximum sustainability index value was 1.98, and obtained in D90B10 fuel at a 3000 W engine load. In terms of enviroeconomics, while the cost of annual CO2 emission of all fuels is low at low engine loads, it increases as engine load increases. It is seen that D90B10 fuel is closest to D100 fuel at low engine loads. Their values are respectively 42.55 USD year(-1) and 43.22 USD year(-1).
