Summary:

In this paper we present a comparison of two different approaches to model three-way catalyst. First, a numerical sample case simulating light-off is used to compare the 1D and the 2D models. The advantages of each code are discussed with respect to required input data, detail level of the output, comparability, and computation time. Thus, the 2D model reveals significant radial temperature gradients inside the monolith during light-off.In a second step, the 2D model is compared with experimental data. One set of data consists of an air/fuel ratio varying sweep at isothermal conditions. Another set was gained by emission measurements during a real driving MVEG tests with varying substrate cell density and inlet conditions. From these experiments the applicability of the model to numerical parameter studies is discussed
