This work investigates the performance characteristic of single-cylinder diesel engines running on biodiesel produced from African breadfruit oil. The extraction, production, and physicochemical analysis were carried out on B100 (100% biodiesel) and B50 (50% petroleum diesel mixed with 50% biodiesel). The effect of speed on thermal efficiency, air-fuel ratio, engine power, fuel consumption, and exhaust temperature were evaluated for B50, B100 and PD. The results showed that at low speed, the thermal efficiency for B50 (33.8 %), B100 (14.95 %) compared to PD (17.8 %), then at peak 3000 rpm B50 (30.56 %), B100 (27.43 %) compared to PD (30.56 %). The engine power produced for B100 (278 watts), B50 (900 watts) compared to PD (294 watts) at low speed, while at peak B100 (1684 watts), B50 (2184 watts) compared to PD (1730 watts) and the fuel consumption at low speed for B100 (0.069 kg.kwh-1), B50 (0.038 kg.kwh-1) compared to PD (0.610 kg.kwh-1) while at peak for B100 (0.032 kg.kwh-1), B50 (0.036 kg.kwh-1) compared to PD (0.204 kg.kwh-1). The samples have similar performance in terms of thermal efficiency, specific fuel consumption and other tested parameters with slight differences for B100 and B50 compared to petroleum diesel.
