This diploma thesis focuses on checking of impact of urea concentration on refractive index of the liquid for selective catalytic reduction. The attention in the introduction part is paid on basic optical terms and laws, particularly on refractive index. Furthermore, the measurement of refraction index is described through particular refractometers and utilization of the refractive index of the liquid in technical practice. In the second part the thesis is focused on problematics of creation of nitrogen oxide emissions, aqueous solution of urea and on description of the construction of the system of selective catalytic reduction. The last, practical part of the thesis includes methodics of measuring of the refractive index of the aqueous solution of urea in various concentrations of urea. The experimental measurement was carried out in laboratories of the Department of Technology and Automobile Transport of Mendel University in Brno. In the conclusion of the practical part are data gained by measuring graphically and statistically evaluated and they are commented appropriately.
