Özet

In the current study, canola oil biodiesel was produced with transesterification method. Biodiesel was added to the neat diesel at the rate of 20% (B20). 50 ppm, 100 ppm and 150 ppm nanoparticles (Quantum Dots) were added to B20. The influences of fuels on combustion, performance and emissions were researched in a single-cylinder diesel engine. Engine experiments were performed at 2200 rpm and engine loads including 4.12, 9.61, 15.10 and 20.60 Nm. It was found that the difference in cylinder pressure between diesel and blended fuels decreased with the increase of engine load. Igntion delay (ID) was shortened with the addition of metallic fuel. Specific fuel consumption (SFC) decreased by 3.08%, 8.70% and 17.69% using D80TCB20C50, D80TCB20C100 and D80TCB20C150 compared to D80TCB20 at 15.10 Nm. Thermal efficiency increased by 83.74%, 89.09% and 89.30% using D80TCB20C50, D80TCB20C100 and D80TCB20C150 compared to D80TCB20 at 15.10 Nm. The lowest maximum pressure rise rate and ringing intensity were determined with neat diesel. HC reduced by about 1.75%, 5.26% and 7.01% D80TCB20C50, D80TCB20C100 and D80TCB20C150 compared to neat diesel at 20.60 Nm. Remarkable reduction was also observed on soot emissions. Soot emissions reduced 83.11%, 85.45% and 86.36% 1.75%, 5.26% and 7.01% D80TCB20C50, D80TCB20C100 and D80TCB20C150 compared to neat diesel at 20.60 Nm. On the other hand, NOx and CO emissions increased with the addition of nanoparticle.
