摘要： A dual-sensor type air-fuel ratio control system for an internal combustion engine. A catalytic converter is disposed within an exhaust pipe for purifying an exhaust gas. A first air-fuel ratio sensor 11 is disposed upstream of the catalyst for detecting concentration of a particular component of the exhaust gas to output a first air-fuel ratio signal V1 indicating the concentration. A second air-fuel ratio sensor 12 is disposed downstream of the catalyst for detecting concentration of the particular exhaust gas component to output a second air-fuel ratio signal V2 indicating the concentration. An apparatus for detecting deterioration of the catalytic converter includes a deterioration decision means 54 for determining deterioration of the catalyst on the basis of at least the second air-fuel ratio signal, a filtering means 50 for filtering the second air-fuel ratio signal to thereby derive a filtered air-fuel ratio signal, and comparison means 51 for comparing the second air-fuel ratio signal with the filtered air-fuel ratio signal. The deterioration decision means compares a deterioration parameter value derived from the result of the comparison with a predetermined value corresponding to a detected operation state of the engine to determine deterioration of the catalyst when the deterioration parameter value exceeds the predetermined value.

A malfunction sensing means responsive to the pressure sensor senses a malfunction when the purge control valve is open and the pressure sensed by the pressure sensor is above a prescribed value. A prohibiting means senses the rate of change and/or the magnitude of the pressure sensed by the pressure sensor with the purge control valve closed and prohibits malfunction sensing by the malfunction sensing means when the rate of change of the pressure exceeds a prescribed rate and/or the magnitude of the pressure exceeds a prescribed value.
