Investigation on the Performance and Emissions of a Biodiesel Engine Fueled with Soybean Biodiesel and Diesel fuel

Biodiesel, which is an alternative to diesel fuel, is made from renewable biological sources such as vegetable oils and animal fats. It is biodegradable and nontoxic has low emission profiles and so is environmentally beneficial. In this study, the effects of different injection angles, compression ratios and different piston bowls insert ignore into journalissuearticles values(Pan and Mexican Hat); on the engine performance and emissions were investigated by using two different fuels which are standard diesel insert ignore into journalissuearticles values(D2); and SME B40insert ignore into journalissuearticles values(Soybean Oil Methyl Ester);. Diesel-RK software was used for the simulation of an internal combustion engine. Simulation results include efficiency and power parameters as piston engine power, torque and specific fuel consumption and also ecological parameters as specific CO2 and NOx emissions. The results showed that the best optimized combination was the Pan piston bowl shape with SME B40 fueled at 22:1 compression ratio and at 50o injection angle.
