    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 procedure and device for diagnosing the increasing speed and the dead time of an exhaust gas probe includes carrying out the diagnosis by comparing a modeled and a measured signal after a default change of a fuel air ratio of an air fuel mixture that is supplied to a combustion engine. The signal is an output signal of the exhaust gas probe or a modeled or measured signal that is derived from the output signal. The device for diagnosing the velocity and the dead time of an exhaust gas probe also includes a comparing unit for comparing the modeled signal with the measured signal for diagnosing the velocity and the dead time of the exhaust gas probe after a default change of a fuel air ratio of an air fuel mixture that is supplied to the combustion engine.

    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 relates to a method and device for diagnosing deviations in a single cylinder lambda control in an internal combustion engine having at least two cylinders and an exhaust gas sensor designed as a broadband lambda sensor, wherein a pump current is evaluated by means of a pump cell and the pump current is used at least temporarily for an individual cylinder lambda control. According to the invention, a pump voltage or a pump voltage change is determined via the pump cell in addition to the pump current and the value is transmitted to a diagnosis apparatus. Deviations in the single cylinder lambda control can thus be better diagnosed without additional material expense according to the invention, which provides advantages in particular in respect of tightened rulemaking in on-board diagnosis. A preferred application of the method is the use in internal combustion engines having multi-bank exhaust systems.
