Exergetic and exergoeconomic analyses of a diesel engine fuelled with diesel - biodiesel blends including green synthesised HC-Glu and HC-Cel nanoparticles

Abstract

In this study, a diesel engine fuelled by diesel-biodiesel blends including HC-Glu and HC-Cel nanoparticles is investigated in the perspectives of exergy and exergoeconomics. B20HC-Glu100, B20HC-Glu200, B20HC-Cel100 and B20HC-Cel200 nanofuels were prepared with HC-Glu and HC-Cel nanoparticles addition of 100 ppm and 200 ppm to B20, respectively. The highest exergy efficiency of test engine was calculated to be 25.23% for B20HC-Cel200, whereas, the cheapest specific exergy cost of crankshaft work was determined to be 142.67 US$/GJ for D100. Nanofuels had better exergetic and exergoeconomic performances compared to their base fuels. However, D100 showed the best exergoeconomic performance compared to nanofuels.
