Abstract: This study dealt with energy and exergy analyses of a John Deere 4045T diesel engine run with no. 2 diesel fuel, Soybean oil Methyl Ester (SME) and High-Oleic soybean oil Methyl Ester (HOME) at 1400 1/min. It was aimed at determining energy and exergy efficiencies, energy losses and exergy destructions of the combustion process and comparing exergetically the fuels used. The specific exergy of the fuels was calculated to be ε_{fuel,No.2 Diesel} > ε_fuel,HOME > ε_fuel,SME, while energy (thermal) and exergy efficiencies were 40.5% and 37.8%, respectively. There were no statistically significant differences between the fuels based on the Tukey method.

Keywords: energy analysis; exergy analysis; availability; genetically modified soybeans; high oleic soybeans; alkyl esters; biodiesel; diesel fuel; diesel engines; diesel combustion; biofuels; energy efficiency; exergy efficiency; energy losses.
