Abstract: A catalyst convertor has maximal efficiency when it reaches working tempera-ture. In a cold start phase efficiency of the catalyst is low and exhaust emissions have high level of air pollutants. The exhaust system optimization, in order to de-crease time of achievement of the catalyst working temperature, caused reduction of the total vehicle emission. Implementation of mathematical models in devel-opment of exhaust systems decrease total costs and reduce time. Mathematical model has to be experimentally verified and calibrated, in order to be useful in the optimization process. Measurement installations have been developed and used for verification of the mathematical model of unsteady heat transfer in ex-haust systems. Comparisons between experimental results and the mathematical model are presented in this paper. Based on obtained results, it can be concluded that there is a good agreement between the model and the experimental results.
