Abstract
A sensor for the monitoring of an NO catalyst having a storage material for the adsorption of NO , the storage material forming the sensitive element of the sensor. As a result, it is possible to measure the instantaneous degree of charging of the storage material, and a quasi-linear control for the storage of NO is made possible. The ability to precisely monitor the degree of charging of the storage material makes it possible to better utilize the storage capacity, and the catalyst can be dimensioned in a more cost-effective manner. The conversion phase of the rich side can be predicted more precisely and consequently be integrated more favorably into the driving cycle. The sensor for the monitoring of an NO catalyst is especially suitable for installation in the exhaust path of an internal combustion engine with direct gasoline injection or of a diesel engine.
