The soot emission is one of the main limiting factors in the Diesel engine performance, due to the heat losses caused during its formation. Studies show that the formation of this product can be reduced by adding oxygenated fuels to replace part of fossil fuels. There is a growing demand for computational models of engines powered by renewable fuels, capable of predicting operational characteristics in different conditions. The objective of this work is to determine, by using computational fluid dynamics (CFD) model, the effects of different percentages of biodiesel on the spatial distributions of soot inside the combustion chamber. Performance and emissions, as well as spatial distributions of soot and temperature were evaluated simulating cases with 8%, 10%, 13%, 15%, 50%, and 100% for mixtures of biodiesel.
