    • During deterioration detection of a catalyst, exhaust gas of a lean air/fuel ratio and exhaust gas of a rich air/fuel ratio are alternately supplied to the catalyst, and decrease of the O2 storage function is detected by obtaining the oxygen occlusion amount in the catalyst, based upon the timing at which, after changeover of the air/fuel ratio of the exhaust gas flowing into the catalyst, the air/fuel ratio of the exhaust gas passed through the catalyst changes to track that air/fuel ratio of the exhaust gas flowing into the catalyst. At this time, the rich air/fuel ratio of the exhaust gas and the lean air/fuel ratio of the exhaust gas supplied to the catalyst are set closer to the stoichiometric air/fuel ratio, the larger is the exhaust flow amount.
    • 在催化剂的劣化检测期间,将稀空气/燃料比的废气和浓空气/燃料比的废气交替地供给到催化剂中,并且检测到O 2存储功能的降低 通过在催化剂中获得氧气吸留量,基于流过催化剂的废气的空气/燃料比的切换之后,通过催化剂的排气的空气/燃料比变化为轨迹 流入催化剂的废气的空气/燃料比。 此时,供给到催化剂的废气的浓空气/燃料比和稀空气/燃料比被设定为接近理论空燃比,废气流量越大。
