Exhaust emissions and engine performance of a diesel engine fueled with biodiesel, scrap tire oil and diesel fuel blends were investigated in this study. Tire oil was pretreated to remove large particles and reduce the sulfur content. The binary fuel blends contained 97% diesel and 3% biodiesel or 3% tire oil and the ternary fuel blend contained 94% diesel, 3% tire oil and 3% biodiesel. Exhaust emissions of oxides of nitrogen (NOx), carbon dioxide (CO2), carbon monoxide (CO), and brake specific fuel consumption were determined from the engine tests. Using tire oil-biodiesel-diesel blend produced lower NOx emissions than biodiesel-diesel blend. The ternary fuel blend reduced the CO emissions compared to tire oil diesel fuel blend. Blending tire oil in biodiesel-diesel fuels would be an alternative method of reducing NOx emissions from biodiesel containing fuel blends.
