摘要： The invention is directed to a method of determining the performance loss of a catalyzer by using a deterioration variable indicative of this performance loss. The catalyzer is affected by operating conditions and is mounted in the exhaust gas flow of an internal combustion engine having a lambda controller operated to provide a two-level response. The method includes the steps of: obtaining a measurement signal from a lambda probe mounted forward of the catalyzer and a test signal from a lambda probe mounted rearward of the catalyzer; forming a relationship between the measurement and the test signals; measuring values of operating variables which affect oxygen storage processes in the catalyzer; and, correcting the deterioration variable based on the values of the operating variables thereby reducing the influence of the operating conditions on the deterioration variable. Because the deterioration variable can be corrected in the manner described above, this variable can be reliably determined for many different operating conditions rather than only for a few selected operating conditions.

摘要： The invention is directed to a connecting circuit for a potential-free lambda probe having a ground line and a signal line and having an offset voltage source which is connected to the ground line. This offset voltage source raises the potential of the ground line to a pregiven value relative to ground. A ground short is directly detectable in the connecting circuit of the invention in that the potential measured at the signal line drops below the offset voltage. In this way, it is no longer required as in conventional circuits to check for a ground short by enriching the mixture of an engine and to monitor the exhaust gas with the lambda probe.

摘要： The invention relates to a method for the continuous lambda control of an internal combustion engine 13 having a catalyzer. The method is carried out by generating a control oscillation FS of pregiven amplitude at least in pregiven operating conditions. This method is based on the recognition that with an increase in amplitude of the control oscillation, the conversion window becomes wider insofar as a maximum amplitude is not exceeded. The conversion window is that range of lambda values wherein the conversion exhibits at least a pregiven quality.

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： A method and an electronic circuit for regenerating an electrical contact are provided in order to remedy the problem of electrical contacts becoming highly resistive over time. Electrical contacts become highly resistive over time, particularly when the contacts are thermally highly stressed and/or exposed to corrosive gases. To remedy this undesired effect and to reestablish the low resistance of the contacts, an electrical regenerating signal is applied to these contacts.

The tank-venting system includes a tank, an adsorption filter having a tank-venting line, a connecting line for connecting the adsorption filter to the tank, a tank-venting valve and a valve line connecting the adsorption filter to the tank-venting valve.

The time-dependent trace is extrapolated and a conclusion is drawn as to the presence of a leak therefrom.
