AbstractIn this study, biodiesel produced from safflower oil was used in a diesel engine as pure fuel. It aimed that the presented availability as a diesel fuel of biodiesel. Results presented as engine performance (torque and specific fuel consumption), exhaust emissions (CO, CO2, HC, NOx and smoke opacity), and combustion analysis. According to test results performed at different injection pressures, biodiesel provided a good engine performance at high injection pressure. Similarly, its exhaust emissions which are already good (expected NOx emission) were better due to the increase injection pressure. Biodiesel increased NOx emission at all conditions. Combustion analysis results shown that it has similar combustion characteristics with diesel fuel. Besides, although ignition delay of biodiesel shortened, its combustion duration extended.
