Abstract

The influences of carbon quantum dot nanoparticles in diesel-biodiesel mixture (D80MCB20) were researched on performance, combustion and exhaust emissions. Test engine was run at 2200 rpm including 4.12, 9.61, 15.10 and 20.60 Nm engine loads. ID period was shortened using nanoparticle apart from D80MCB20 CQD 180 ppm. Nanoparticle caused to decrease SFC. CO and HC declined by about 0.76%, 18.02%, 20.30% and 19.48%, 28.57% and 31.16% in case of D80MCB20 CQD 60 ppm, D80MCB20 CQD 120 ppm and D80MCB20 CQD 180 ppm usage according to D80MCB20 at 20.60 Nm respectively. Nonetheless, 48.29%, 55.44% and 56.26% increases were specified on NOx using D80MCB20 CQD 60 ppm, D80MCB20 CQD 120 ppm and D80MCB20 CQD 180 ppm compared to D80MCB20 at 20.60 Nm. It was seen that the carbon quantum dot nanoparticle additive into the diesel-microwave corn biodiesel mixture was a potential candidate to boost performance and reduce CO, HC and soot emissions.
