Abstract
The primary purpose of this study was to examine the influence of cobalt oxide nanoparticle (nano- Co3O4) fraction on soyabean oil-based biodiesel mixture which was used in a four-stroke single cylinder compression ignition engine test rig. In order to create four unique mixtures initially soyabean oil had been mixed with the diesel at a concentration of 20 percent to create biodiesel (SD20) and further the nanoparticles were then introduced to form three ternary blends with 30 60 or 90 ppm of nano-Co3O4in biodiesel. According to the findings of this research incorporating 60 ppm of nano-Co3O4 to soyabean biodiesel enhanced the brake thermal efficacy (BTE) by 40.25 % comparing to the SD20 blend. Additionally the presence of nano-Co3O4 in biodiesel at a proportion of 90 ppm had caused a minimization of CO emissions by 68.57 %. Further amalgamating 60 ppm of nano-Co3O4 in biodiesel abridged the HC emission of biodiesel by 35.78 %. In contrast introducing 30 ppm of nano-Co3O4 in biodiesel increased the NOx emissions comparing to the biodiesel on an average at all the loading scenarios.
