At the moment, the operating conditions for best conversion of limited emissions of gasoline engines are controlled by lambda probes upstream and downstream of the three-way catalyst. Their signals are the basis for complex oxygen loading models of the catalyst. A novel approach is to directly determine the catalyst state without lambda probes via a contactless monitoring system based on the interaction of electromagnetic waves with the catalyst. We could show previously that the resonance frequencies of the catalyst-filled housing are strongly correlated with the oxygen loading of the catalyst. In this study, it is shown that cross-effects of water, carbon monoxide, carbon dioxide, and gas flow rate can be neglected.
