Determination of combustion characteristics of olive pomace biodiesel – Eurodiesel fuel mixtures

ABSTRACT

In this study, Olive Pomace Methyl Ester (PME) was obtained by subjecting pomace oil, obtained from olive pomace residues after olive oil production, to transesterification process. PME was mixed volumetrically at the rate of 5% (B5),7% (B7), 10% (B10) and 100% (B100); and the engine performance of these mixtures (Power, Torque, Specific fuel consumption), combustion characteristic in cylinder (in-cylinder pressure values) were detected. According to the results, the highest power values were obtained as 43.8 kW (3000 rpm), 42.1 kW (300 rpm), 40.2 kW (3000 rpm), 37.8 kW (2500 rpm), 33.5 kW (3000 rpm) respectively, in Euro Diesel, B5, B7, B10, and B100 fuels. According to the obtained results, the highest torque values were found as 184.3 Nm (2000 rpm), 173.3 Nm (2000 rpm), 169 Nm (2000 rpm), 158.32 Nm (2000 rpm) and 142.9 Nm (2000 rpm) respectively, in Eurodiesel, B5, B7, B10, and B100. According to the test results, the lowest specific fuel consumptions were detected as 220.62 gr/kWh (2000 rpm), 231 gr/kWh (2000 rpm), 252 gr/kWh (2000 rpm), 283 gr/kWh (2000 rpm) and 363 gr/kWh (2000 rpm) respectively, in Eurodiesel, B5, B7, B10 and B100.
