| Summary: | Abstract The paper presents the results of gas dynamic calculation and strength analysis required to optimize the mathematical model of the body of the catalytic collector of a passenger car. Based on the obtained results of numerical modeling, the optimization of the case was performed. As a result of the gas-dynamic calculation, the optimal variant of the catalytic collector housing with the required uniformity of the exhaust gas flow in the input section of the catalyst (coefficient of unevenness (UI > 0.8)) was selected. According to the results of the strength analysis, stainless steel was selected to withstand emerging mechanical stresses at maximum temperatures up to 600 °C. |
