| description | In this article reviewed the nonstationary process of heat transfer on warm-up stage of threeway catalytic converter of exhaust gases, installed on automobile with gasoline internal combustion engines. Developed and described a mathematical model for calculating the time of heating of the solid structure of the catalytic сonverter. The initial data are the design parameters and speed rotation mode of the engine, ambient temperature, geometric and thermophysical parameters of the catalytic сonverter. The algorithm of calculation of heating time of the catalytic сonverter includes sequentially the thermal design of the internal combustion engine, the calculation of heat losses in the exhaust manifold, the calculation of heat fluxes in the catalytic сonverter. The mathematical model allows calculating the heating time of the catalytic Converter to its operating temperature at different set of initial data. Analysis of obtained results enables to determine the conditions for shortening the time of heating of the catalytic Converter and, consequently, to improve the efficiency of its work. |
