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

Abstract

In this study, performance and emission characteristics of sunflower oil methylesters (sunflower oil biodiesel/SOB) and diesel were studied in between 1400-2600 engine speed. After determining fuel properties, performance andemissions of the test engine, energy and exergy analysis were conducted byusing experimental data attained from the experiments. Analyses wereperformed at 1800 rpm (revolutions per minute) engine speed which gavemaximum torque value. With the aid of experimental data and energy balancesand exergy rates for the determined control volume which is the whole engine,first and second law efficiencies related with namely quantity and quality weredetermined for the test fuels, SOB and diesel fuel. Conclusions were evaluatedto determine the effects of test fuels on 1st law and 2nd law efficiencyperformance.
