| Abstract This study eventuated in two stages, the first is to extract biodiesel fuel from crude vegetable oil of sunflower and soybean oils, and the second stage is to use these extracted fuels to operate diesel engine. Three types of fuel used, the first fuel is conventional diesel fuels for comparison, the second and third types of fuel consist of four blends (B25, B50, B75, B100) for each type of sunflower and soybean biodiesel fuels. The fuels were used in the engine to find the criteria of performance of the engine which includes(Torque, Brake power, Specific fuel consumption) and discovers in the combustion products on (O2, CO, NO, CO2) for each type of fuel. The result of this study shows that the maximum performance of the engine is reached when the conventional diesel fuel is used, but increased the pollutants in atmosphere. The use of biodiesel fuel in the engine decreases the performance of the engine, but it will decrease emitting of (CO2, CO) and increase(NO) comparing with conventional diesel fuel. The results show decrease 31.9% in engine power when use the fuel (B100-SF) and decrease 18.2% of CO2 comparing with conventional diesel fuel. The fuel(B100-SB) shows decrease 33.7% in engine power and decrease 38.6% of CO2 when comparing with conventional diesel fuel. In addition the blends (B25-SF, B50-SF, B75-SF) give better engine performance and less pollutants emission when comparing with identical blends of fuel (B25-SB, B50-SB, B75-SB). | ||
