IPC: F02D45/00
Filed: 1993-09-02
Abstract: PURPOSE:To diagnose deterioration of an oxygen sensor provided downstream from a catalyst with high accuracy without being influenced by change of oxygen storage effect of the catalyst. CONSTITUTION:When prescribed diagnostic condition is set up (S21 to S23), feedback control of an air-fuel ratio is carried out using only output of an oxygen sensor provided downstream from a catalyst (S24). In such a feedback control condition, a control cycle is measured (S25), and the phase difference between the output wave of an oxygen sensor provided upstream from the catalyst and the output wave of the oxygen sensor provided downstream from the catalyst is detected (S26). Reduction of oxygen storage effect of the catalyst is judged from the phase difference (S27), and a first or second judging level which is set according to judging result is compared with the control cycle (S28, S31), and then deterioration of the oxygen sensor provided downstream from the catalyst is judged in the case where a real control cycle is longer than that of the judging level (S29).
