Abstract: PURPOSE:To enable the evaluation of the performance of an oxygen sensor with the caluculation of a control frequency thereof by continuously measuring rising and falling response times of the sensor while cyclically varying the air- fuel ratio of a combustion gas. CONSTITUTION:According to an air-fuel ratio varying signal S generated from an air-fuel ratio varying signal generator 16, an electromagnetic valve 10 is driven and a combustion gas varies from the lean side to the over rich side. An oxygen sensor 12 (17 and 18) is provided on an exhaust tube 11 of a combustion chamber 5 to control the air-fuel ratio and an output voltage Vs is outputted according to a waveform of an air-fuel ratio varying signal S. The output voltage Vs is inputted into a waveform processor 19 with the air-fuel ratio varying signal S of the air-fuel ratio signal generator 16 to continuously measure the rise time and the fall time of the output voltage Vs over many cycles. From the measured times, a control frequency is calculated to evaluate the performance of the oxygen sensor.
