The aim of our work is to understand the dispersion of the plume of exhaust gases of two vehicles with and without catalyst. CFX10.0 calculation code with the eddy viscosity model (k-ε) was used to simulate the concentrations of gaseous pollutants (NOx, CO). The numerical results were compared to those found in the literature [2], obtained experimentally with two non-moving vehicles in an isolated environment under stable conditions. This numerical simulation showed that pollutant concentrations decrease exponentially in all directions, and show the effect of the presence of the catalyst on the dispersion of pollutants NOx. We found that an angle of 30° to the exit at a great influence on the dispersion of the pollutant and provides a good dispersion of the pollutants CO.
