The climate changes of car emission regulation recenntly requirement for cleaner engine combustion. Reduction of engine emission could play a key role on public health. Addition of 2-20% biodiesel into diesel fuel could significantly reduce exhaust emission. Biodiesel could improve engine combustion and reduce diesel gases except NOx. Using additives is a successful way to diminish NOx emission. Among fuel additives, water could effectively reduce NOx emission beside other advantages. In present research, cerium oxide was employed to prevent disadvantages from thermal effect of water during combustion. In present study, emission characteristics of combustion of emulsified B5 (95% diesel fuel and 5% Biodiesel) containing 60 ppm cerium oxide and 5% water were scrutinized. Present findings showed that B5W6 emulsion fuel (B5 containing 6% water) reduced CO, HC, and NOx emission effectively. Besides, results obtained showed that nano cerium oxide particles reduced more emission compared with B5W6..
