The model can be used for estimation of the impact of pollutant emissions from road vehicles on the environment. The finite volume method has been used for model formulation. Equations obtained after discretisation are solved by using different methods like Runge-Kutta, Crank-Nicholson or decomposition methods. On the basis of the numerical simulation, conclusions are formulated about the numerical effectiveness of the integration methods used. In the paper, a problem of nitrogen oxides dispersion is formulated and solved, whereby chemical reactions are included in considerations. The model presented in the paper has been used for numerical calculations of car exhaust pollutant concentrations in a real car park. The last part of the paper presents some numerical results of calculations, which include emissions after cold start of engines.}, type={Article}, title={Numerical modelling of car exhaust pollutant dispersion with chemical reactions}, URL={http://journals.pan.pl/Content/124967/PDF-MASTER/7_MECHANICAL_52_2005_1_Brzozowski_Numerical.pdf}, keywords={exhaust emission, dispersion, modelling}, }
