Abstract

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 (Pan and Mexican Hat) on the engine performance

and emissions were investigated by using two different fuels which are standard diesel (D2) and

SME B40(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.

Keywords
