Abstract
We use fuel oil as an alternative fuel in compression ignition engines without modification. In this study, we performed tests at different engine speeds using diesel fuel oil fuel blends in a compression ignition engine. Energy and exergy analysis was carried out using the performance and emission values got from these tests. Through energy analysis, the energy distribution of the engine was determined and the thermal efficiency was calculated. The highest thermal efficiency is 34.76% on F40 fuel at 2250 rpm. In the exergy analysis, fuel exergy, exhaust exergy, entropy production, and exergy efficiency were calculated. The highest exergy destruction is 17.36 kW at 3250 rpm on D100 fuel. The exergy efficiency increases with engine speed. The highest exergy efficiency is 28.2% on F40 fuel at 2250 rpm.
