ABSTRACT
In this experimental study, the performance, combustion and emission analysis of the combined effect of acetone and Zinc Oxide (ZnO) dispersed diesel–biodiesel (B20) blends were done in four-stroke, single-cylinder and water-cooled diesel engine. ZnO was synthesized by the solvothermal method using cow urine as a solvent and reducing agent. The synthesized ZnO was characterized by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM). The biodiesel was produced from waste cooking oil through a trans-esterification process. The synthesized ZnO was dispersed in 10, 20 and 30 ppm with diesel–biodiesel blend along with 10% of acetone to form B20A10Zn10, B20A10Zn20 and B20A10Zn30 test fuels. The experimental results show that adding acetone and ZnO with diesel–biodiesel blend tends to promising physiochemical properties of the test fuels and produced better results in performance and emission. The test fuel, B20A10Zn30, gave a better outcome than all other fuels and recorded a 0.4% increase in Brake Thermal Efficiency (BTE), while there was an 8% increase in Brake Specific Fuel Consumption (BSFC). Compared to diesel, the emissions, such as Carbon Monoxide (CO), Unburned Hydrocarbon (UHC), Oxides of Nitrogen (NOx), and smoke, were 7.97%, 20%, 1.8% and 1.49% lower than the conventional diesel.
