Against the background of the current discussions on the reduction in CO2 emissions, the development of lean-burn engines is acquiring increasing importance. In order to meet future emissions limits, new strategies are required, especially for NOx conversion. One technique developed in recent years for the conversion of NOx in lean exhaust gases is the NOx adsorber catalyst, which stores NOx in lean operating conditions and must periodically be regenerated with rich exhaust gas.In this paper, the influence of catalyst substrate design on NOx conversion is described. In addition NOx conversion measurements with NOx adsorbers of various cell densities, variable diameter/length ratios as well as smooth and structured channel walls are carried out.
