Abstract
An internal combustion engine has a NOX storage catalyst. A storage capacity (NOX_STC) of the NOX storage catalyst is determined for the purpose of operating the internal combustion engine. The temperature (TEMP) of the NOX storage catalyst is increased if the storage capacity (NOX_STC) is less than a predefined threshold value.
