发明名称 Method and arrangement for monitoring a lambda probe in an internal combustion engine
摘要 The invention is directed to a method and an arrangement for monitoring deterioration of lambda probes in the context of a two-probe control. The signal of the lambda probe forward of the converter functions to control the lambda controller and the signal of the lambda probe rearward of the converter influences the lambda controller via an actuating variable and the degree to which the controller is influenced operates for monitoring of the probe forward of the converter. With this method and arrangement, the quality and deterioration of the lambda probe forward of the converter are advantageously detected and, if required, an alarm signal is generated.
