Performance, emission, energetic and exergetic analyses of a compression ignition engine fuelled with sunflower oil methyl esters

In this study, performance and emission characteristics of sunflower oil methyl esters (sunflower oil biodiesel/SOB) and diesel were studied in between 1400-2600 engine speed. After determining fuel properties, performance and emissions of the test engine, energy and exergy analysis were conducted by using experimental data attained from the experiments. Analyses were performed at 1800 rpm (revolutions per minute) engine speed which gave maximum torque value. With the aid of experimental data and energy balances and exergy rates for the determined control volume which is the whole engine, first and second law efficiencies related with namely quantity and quality were determined for the test fuels, SOB and diesel fuel. Conclusions were evaluated to determine the effects of test fuels on 1st law and 2nd law efficiency performance.
