Zusammenfassung: | A method for adjusting the temperature of an exhaust gas aftertreatment device is disclosed. A first characteristic temperature value for an oxidative carbon monoxide conversion and a second characteristic temperature value for an oxidative hydrocarbon conversion are assigned to an oxidation catalytic converter, and a third characteristic temperature value for a reductive NOx conversion is assigned to an SCR catalytic converter. Different respective values for injection parameters of injection processes for fuel injections into combustion chambers of the internal combustion engine and/or the heating output of an electric heating element are set upon reaching the first and the second characteristic temperature values for the temperature of the oxidation catalytic converter and upon reaching the third characteristic temperature value for the temperature of the SCR catalytic converter. |
