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 biologicalsources such as vegetable oils and animal fats. It is biodegradable and nontoxic has low emissionprofiles and so is environmentally beneficial. In this study, the effects of different injection angles,compression ratios and different piston bowls (Pan and Mexican Hat) on the engine performanceand emissions were investigated by using two different fuels which are standard diesel (D2) andSME B40(Soybean Oil Methyl Ester). Diesel-RK software was used for the simulation of an internalcombustion engine. Simulation results include efficiency and power parameters as piston enginepower, torque and specific fuel consumption and also ecological parameters as specific CO2 andNOx emissions. The results showed that the best optimized combination was the Pan piston bowlshape with SME B40 fueled at 22:1 compression ratio and at 50o injection angle.
