Özet

In the present study, the influences of the carbon quantum dots nanoparticle addition to diesel- microwave- assisted corn oil biodiesel-dimethyl carbonate fuel mixtures on combustion, performance and emissions were experimentally researched in a DI diesel engine at 4.12, 9.61, 15.10 and 20.60 Nm. Lower in-cylinder pressure was measured using fuel mixtures according to diesel. The rise of carbon quantum dot fraction in the fuel mixtures lead to decrease ID. It was also found that SFC declined with the addition of carbon quantum dot nanoparticle in the fuel blends. ITE increased by 6.66 % using CF QD120 ppm according to CF at 15.10 Nm. CD was shortened with fuel mixtures compared to diesel. Test results also showed that clear increase on MPRR and RI has been realized with fuel mixtures. Higher CO was measured using fuel mixtues. Nevertheless, the addition of carbon quantum dot to CF decreased CO emissions. CO declined by about 14.12 % with CF QD120 ppm according to CF at 20.60 Nm. Significant decrease was measured using carbon quantum dot addition on soot emissions whereas NOx emissions increased. Soot emissions reduced by 19 % with CF QD120 ppm compared to CF at 20.6 Nm.
