Exhaust emissions are the major challenges of diesel engines and are significant environmental pollutants. This study investigates the exhaust emission characteristics of a diesel engine fueled with three types of fuel; biodiesel (B100), biodiesel blend of 50 % pure biodiesel (produced from African Breadfruit oil) and 50 % petroleum diesel (B50) and petroleum diesel (PD). The study compared the exhaust emissions characteristics such has oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2) and nitrogen oxide (NOx) using Kigas 100 exhaust gas analyzer. The results show that B100 (0.01 ppm) and B50 (0.01 ppm) displayed lower CO emission compared to PD (0.02 ppm). CO2 emissions for B100 (1.66 ppm) and B50 (1.9 ppm) were lower than that of PD (2.1 ppm). NOx emission shows that B100 (400 ppm) was higher than B50 (390 ppm) and PD (328 ppm). Based on this study it is concluded that the biodiesel was an environmentally friendly, less harmful and alternative fuel for diesel engine compared to PD. However, the petroleum diesel produced lesser NOx emission compared B100 and B50 which is one of the major challenges of diesel engine designers.
