Abstract
Pollution in the world has been the focus of attention in recent years due to its sharp increase. The causes are multiple, and one of them is the emission of pollutants in the rail transport sector. For this, the behavior of the fuel must be known. In the present work, a study of the behavior of a locomotive engine of the VALE company has been carried out. This locomotive has a GE FDL16 model engine. Numerical simulation was performed with AVL-FIRE™ software using detailed chemical kinetics as a combustion model with a kinetics mechanism with 109 species and 543 reactions for combustion predictions, PAH and soot formation validated for the use of n-heptane individually. When comparing the indicated power results with the experimental data, it was observed that the numerical values are consistent and very close. Having a percentage error with the mean value of the indicated power of 2.25%. This shows that the mechanism and the simulation allow reproducing the experimental values. The behavior of the average soot fraction and the average NO fraction for this type of engines was also analyzed.
