Abstract: A method for operating an internal combustion engine by introducing air, in which the air is conducted into the induction region of the internal combustion engine following shutoff of the internal combustion engine. If necessary, the intake valves and the exhaust valves of at least one cylinder are moved into a position in which at least one intake valve and one exhaust valve of a combustion chamber of the internal combustion engine are open simultaneously. The method may be used in for an internal combustion engine having an electric turbocharger for the introduction of air.

Abstract: A method for operating a catalytic converter arranged in the exhaust gas of an internal combustion engine. The composition of exhaust gas being controlled in front of the catalytic converter by adding a reducing agent that promotes the regeneration of the catalytic converter. The composition of the exhaust gas being detected with the aid of an exhaust-gas sensor positioned downstream from the catalytic converter. A time lag between the start of controlling the composition of the exhaust gas in front of the catalytic converter and the detection of a change in the composition after the catalytic converter are evaluated. In order to be able to determine the end of a regeneration phase of the catalytic converter in a safe and reliable manner, the gradient of an output signal of the exhaust-gas sensor is evaluated.
