    摘要： A catalyst deterioration determination system for determining deterioration of an exhaust gas purification catalyst having a capability of storing oxygen determines deterioration of the exhaust gas purification catalyst on the basis of its oxygen storage capacity. The system includes an oxygen concentration sensor provided downstream of the catalyst and having characteristics by which as rich gas components in exhaust gas increase, the oxygen concentration sensor outputs a measurement value of the oxygen concentration corresponding to a richer air-fuel ratio. When determining deterioration, the system performs a rich shift mode in which the exhaust gas air-fuel ratio is shifted from a lean air-fuel ratio to a rich air-fuel ratio and a lean shift mode in which the exhaust gas air-fuel ratio is shifted from a rich air-fuel ratio to a lean air-fuel ratio by exhaust gas air-fuel ratio control means, based on the measurement value of the oxygen concentration sensor. The rate of change of the exhaust gas air-fuel ratio in at least the lean shift mode among the rich shift mode and the lean shift mode is limited to a predetermined rate of change or lower, and the rate of change of the exhaust gas air-fuel ratio in the rich shift mode is set higher than the rate of change of the exhaust gas air furl ratio in the lean shift mode.

    摘要翻译： 用于确定具有存储氧气的废气净化催化剂的劣化的催化剂劣化确定系统基于其储氧能力来确定废气净化催化剂的劣化。 该系统包括设置在催化剂下游的氧浓度传感器，其特征在于，随着废气中富含气体成分的增加，氧浓度传感器输出对应于较浓空燃比的氧浓度的测量值。 当确定劣化时，系统执行富排气模式，其中废气空燃比从稀空燃比转变为浓空气燃料比和贫排气模式，其中排气空燃比 基于氧浓度传感器的测量值，通过废气空燃比控制装置从浓空燃比转变为稀空燃比。 在富变换模式和稀班模式之间的至少贫偏模式中的排气空燃比的变化率被限制在预定变化率或更低的变化率，并且排气空气的变化率 富排气模式中的燃料比设定为高于贫排气模式中的废气空气流量比的变化率。

    摘要： A catalyst deterioration diagnosing apparatus is provided with means for performing stoichiometric feedback control on the air-fuel ratio based on at least output from an upstream air-fuel ratio sensor provided upstream of a catalyst, means for measuring the oxygen storage capacity of the catalyst, and means for correcting the measured value of the oxygen storage capacity based on at least the output behavior of a downstream air-fuel ratio sensor provided downstream of the catalyst during the stoichiometric feedback control. The measured value of the oxygen storage capacity is corrected using the output behavior of the downstream air-fuel ratio sensor during stoichiometric feedback control. The diagnostic is performed after eliminating the effects from sulfur by correcting the measured value to a value corresponding to when low sulfur fuel is used, which makes it possible to prevent an erroneous diagnosis from being made.

    摘要： The oxygen storage capacity preceding a previous oxygen storage capacity and the previous oxygen storage capacity of each of an upstream catalyst and a downstream catalyst are measured, and a present oxygen storage capacity of the downstream catalyst is measured. Then, sulfur poisoning of the upstream catalyst and the downstream catalyst is detected on the basis of an oxygen storage capacity change amount of each of the upstream catalyst and the downstream catalyst from the oxygen storage capacity preceding the previous one to the previous oxygen storage capacity, and the oxygen storage capacity change amount of the downstream catalyst from the previous oxygen storage capacity to the present oxygen storage capacity. The presence/absence of the sulfur poisoning can be accurately detected by utilizing the difference between the manners of sulfur poisoning of the two catalysts.

    摘要： Active air-fuel ratio control is performed to alternately control an air-fuel ratio in an area located upstream of a catalyst between a lean side and a rich side. Switching is carried out between lean control and rich control at the same time when an output from a post-catalyst sensor reaches a threshold. Whether the catalyst is normal or abnormal is determined based on the rate of a change in the output from the post-catalyst sensor between a first point of time when a pre-catalyst air-fuel ratio reaches stoichiometry after the output from the post-catalyst sensor reaches the threshold and a second point of time when the output from the post-catalyst sensor reaches the threshold next time.

    摘要： Active air-fuel ratio control is performed to alternately control an air-fuel ratio in an area located upstream of a catalyst between a lean side and a rich side. The amount of oxygen absorbed and released by the catalyst during lean control and rich control of the air-fuel ratio is measured. When an output from the post-catalyst sensor reaches a predetermined threshold, switching is carried out between the lean control and the rich control, and the measurement of the amount of oxygen is ended. The threshold is set to be reached before the output from the post-catalyst sensor reaches a predetermined reference value. Whether the catalyst is normal or abnormal is determined based on the amount of oxygen measured until the output from the post-catalyst sensor reaches the threshold and behavior of the output from the post-catalyst sensor observed after the output from the post-catalyst sensor reaches the threshold.
