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.

摘要： A circuit configuration for operating a gas sensor is described, including a reference gas space in which an electrode is situated which is supplied with a reference gas pump current to maintain the concentration of the reference gas. A diagnostic system determines a concentration change of the reference gas via a change in the reference pump current and a time-based evaluation of the sensor signal of the gas sensor.

摘要： An internal combustion engine (1), especially for a motor vehicle, is described, which has a catalytic converter (12) which can be loaded with and unloaded of nitrogen oxides. An NOx sensor (14) is provided with which NOx emissions can be measured downstream of the catalytic converter (12). The catalytic converter (12) can be only partially loaded by a control apparatus (18). An increased NOx emission can be generated forward of or in the catalytic converter (12) by the control apparatus (18). A conclusion can be drawn as to the operability of the catalytic converter (12) by the control apparatus (18) from NOx emissions measured downstream.

摘要： A method for diagnosing the dynamic characteristics of a lambda sensor, which is used at least intermittently for a cylinder-individual lambda closed-loop control, which provides for at least one actuating variable of the lambda closed-loop control to be detected and compared to a specifiable maximum threshold, and, if the maximum threshold is exceeded, the dynamic response of the lambda sensor is deemed insufficient with respect to the usability for the cylinder-individual lambda closed-loop control.

摘要： A circuit arrangement is proposed to diagnose a heating resistor, which is connected in series with a first switch, which connects the heating resistor to a power source for operation of the heating resistor with a heating current. Provision is made for means to operate the heating resistor with a diagnostic current during a cut-out time of the heating current and for means to acquire a diagnostic voltage as a measurement for the voltages occurring at the heating resistor as well as means to calculate the resistance of the heating resistor, which is taken as a basis for the diagnosis.
