Modern combustion engines are required to produce high power output while maintaining low specific fuel consumption and low emission level. Cars then need to be equipped with increasingly complex systems of catalytic converters, enabling oxidation of carbon monoxide, unburned hydrocarbons, filtration and oxidation of soot, and reduction of nitrogen oxides. Design of these complex systems includes optimization of pressure and heat losses. With increasing availability of processing power and effective 1D models it is possible to simulate the dynamic behavior of catalytic converters system on common desktop computers. In this work, a standard 1D-model of a monolith converter with optimized numerical solver is coupled to a commercial 3D CFD processing software via a newly developed interface. Simulation results obtained by the 1D-channel model alone and the coupled 3D-CFD with representative 1D-channels are compared.
