摘要： The invention concerns a procedure to determine the oxygen storage capability of an emission control system with an exhaust gas sensor with discrete-level ability disposed in front of the emission control system.If in a period of time before the determination of the oxygen storage capability, the control intervention of the exhaust gas sensor is ascertained, and if this mean value is taken into consideration when calculating the fuel-delivery control phase during the determination of the oxygen storage capability of the emission control system, or if this mean value is used to correct the lambda value used to calculate the amount of oxygen stored, an improved measuring accuracy can be achieved while using a cost effective discrete level sensor. In that during the rich or lean operation of the cycle to determine the oxygen storage capability, the mean value of the control intervention is used for the calculation, pre-control errors are compensated for, as they can arise, for example, through dispersion of the injection valves or errors in the acquisition of cylinder fill. If the mean value is used to correct the lambda value, the amount of oxygen stored can be more accurately determined as a result of the measured air mass. In the procedure according to the invention, a cost effective step discrete-level sensor can be used in front of the emission control system.

摘要： A method for operating an internal combustion engine and a device for implementing the method may allow a catalytic converter diagnosis with a high degree of accuracy. At least one catalytic converter is positioned in the exhaust-gas region of the internal combustion engine, and a lambda sensor, which is configured as broadband lambda sensor, is positioned downstream from the catalytic converter or downstream from a section of the catalytic converter. The catalytic converter diagnosis is based on the evaluation of a measure for the oxygen storage capacity of the catalytic converter/within the catalytic converter. An at least approximately empty/filled oxygen reservoir of the catalytic converter is assumed. A change in the lambda setpoint value of the internal combustion engine to an excess air factor lambda that is greater than 1/less than 1 follows. Subsequently, a first change of the lambda signal is detected initially. Determined is a measure for the oxygen stored/discharged following the first change of the lambda signal. The determination of the stored/discharged oxygen is terminated if either a second change in the lambda signal is detected or if the measure of oxygen exceeds a threshold value.

摘要： The invention relates to a procedure and a device for diagnosing the increasing speed and the dead time of an exhaust gas probe, which is arranged in the exhaust gas duct of a combustion engine, whereby the diagnosis is carried out due to a comparison of a modeled and a measured signal after a default change of a fuel air ratio of an air fuel mixture that is supplied to the combustion engine and whereby the signal is an output signal of the exhaust gas probe or a modeled or measured signal that is derived from the output signal. It is thereby provided that a first extreme value is determined in the course of the modeled signal and that a first point of time and a first starting value are determined if the modeled signal deviates by a default amount from the first extreme value, that a second extreme value in the course of the measured signal is determined and that a second point of time and a second starting value are determined, if the measured signal deviates from the second extreme value by a pre-determined amount, that a first integral is created over a pre-determined period of time, beginning at the first point of time above the different between the first starting value and the modeled signal and that a second integral is created over a second period of time, beginning at the second point of time, above the difference between the second starting value and the measured signal, that the second period of time is equal to the pre-determined period of time or that the end of the second period of time related to the point of time of the change of the fuel air ratio or related to a first point of time is determined and that from a quantitative comparison between the first integral and the second integral a quantitative comparative value is created, which indicates the increasing speed and/or the dead time of the exhaust gas probe. The procedure and the device enable a secure diagnosis of the increasing speed and the dead time of exhaust gas probes in the exhaust gas of combustion engines depending on the changing direction of the fuel air ratio that is supplied to the combustion engine.

摘要： The invention concerns a procedure and a device for diagnosing the dynamic of an exhaust gas sensor, which is arranged in an exhaust gas duct of a combustion engine and with which a parameter of the gas mixture that is supplied to the combustion engine is regulated by a control loop. It is thereby provided according to the invention that during a diagnosing period a temporal deflection of a regulation correcting variable for the parameter that is derived from an output signal of the exhaust gas sensor or a temporal course of the output signal of the exhaust gas sensor is used for the diagnosis and that the dynamic of the exhaust gas sensor is assumed in an evaluation algorithm. Thereby an improvement of the on-board diagnosis of the dynamic of the exhaust gas sensor can be achieved and in particular lambda probes, which provide a slowing down of their responding behavior, can be detected early on.

摘要： A method and device for operating an internal combustion engine, which diagnose and/or adapt the exhaust-gas recirculation system for, in particular, multibranch internal combustion engines. In this context, the internal combustion engine includes at least one adsorption catalyst in at least one exhaust branch. In addition, at least one exhaust-gas recirculation duct is provided, which is equipped with an exhaust-gas recirculation valve and feeds exhaust gas from the at least one exhaust branch back into at least one air-supply duct, a level of pollutant stored in the at least one adsorption catalyst being ascertained in a first operating state of the internal combustion engine when the exhaust-gas recirculation valve is at least partially open, so that a first value for the pollutant level is produced. In a second operating state of the internal combustion engine, a second value for the pollutant level in the at least one adsorption catalyst is ascertained when exhaust-gas recirculation valve is closed. The first value of the pollutant level is compared to the second value of the pollutant level. A diagnosis and/or an adaptation of an exhaust-gas recirculation system formed by the at least one exhaust-gas recirculation duct, along with its exhaust-gas recirculation valve and its drive circuit, is carried out as a function of the comparison result.
