摘要： 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.

摘要： An exhaust gas catalytic converter is laden with oxygen until it is saturated at least upstream of an exhaust gas probe. A predefined first rich air/fuel ration is set in a combustion chamber of a cylinder. A first oxygen storage capacity value is determined as a function of the measurement signal of an exhaust gas probe and the predefined first rich air/fuel ratio. The exhaust gas catalytic converter is laden with oxygen until it is saturated. A predefined second rich air/fuel ration is set in the combustion chamber of the cylinder. A second oxygen storage capacity value is determined as a function of the measurement signal of the exhaust gas probe and the predefined second rich air/fuel ration. A corrected oxygen storage capacity value is determined as a function of the first and second oxygen storage capacity values.

摘要： An internal combustion engine has at least one cylinder and an exhaust gas tract, in which an exhaust gas sensor, that can be heated in a controlled manner, is arranged. An exhaust gas temperature of an exhaust gas flowing in the exhaust gas tract is determined as a function of the heating power (P_HEAT) supplied to the exhaust gas sensor. An estimated value of the exhaust gas temperature is determined as a function of a physical model of the combustion of the air/fuel mixture and of the exhaust gas tract as a function of at least one operating variable of the internal combustion engine, but independent of the heating power supplied to the exhaust gas sensor. Model parameters of the physical model are adapted as a function of a deviation of the estimated value and of the exhaust gas temperature determined by the supplied heating power.

摘要： The invention relates to a waste gas probe which is disposed in an internal combustion engine, comprising a plurality of cylinders and injection valves associated with the cylinders, in order to measure fuel. The waste gas probe is arranged in a waste gas tract and the measuring signal thereof is characteristic for the air/fuel ratio in the respective cylinder. The measuring signal is detected in relation to a reference position of the piston of the respective cylinder at a predefined crankshaft angle and associated with a respective cylinder. A manipulated variable which is used to influence the air/fuel ration in the respective cylinder according to the measuring signal detected for the respective cylinder is produced by a controller. The predefined crankshaft angle is adapted according to an instability criterion of the controller.
