    • A control device for an internal combustion engine, equipped with: an exhaust purification catalyst capable of storing oxygen; a downstream-side air-fuel ratio sensor arranged downstream in the direction of flow of exhaust from the exhaust purification catalyst; and an air-fuel ratio control device that controls the air-fuel ratio such that air-fuel ratio of the exhaust flowing into the exhaust purification catalyst reaches a target air-fuel ratio. The control device changes the target air-fuel ratio to a lean air-fuel ratio setting when the exhaust air-fuel ratio detected by the downstream-side air-fuel ratio sensor reaches a rich air-fuel ratio, and then changes the target air-fuel ratio to a slightly lean air-fuel ratio setting before the exhaust air-fuel ratio detected by the downstream-side air-fuel ratio sensor reaches a lean air-fuel ratio, and then changes the target air-fuel ratio to a rich air-fuel ratio setting when the exhaust air-fuel ratio detected by the downstream-side air-fuel ratio sensor reaches a lean air-fuel ratio, and then changes the target air-fuel ratio to a slightly rich air-fuel ratio setting before the exhaust air-fuel ratio detected by the downstream-side air-fuel ratio sensor reaches a rich air-fuel ratio.
    • 一种用于内燃机的控制装置,配备有能够存储氧气的排气净化催化剂; 下游侧空燃比传感器,其布置在排气净化催化剂的排气流动方向的下游; 以及空燃比控制装置,其使流入所述排气净化催化剂的排气的空燃比达到目标空燃比来控制所述空燃比。 当由下游侧空燃比传感器检测到的排气空燃比达到浓空燃比时,控制装置将目标空燃比变更为稀空燃比设定,然后将目标空气 - 燃料比与由下游侧空燃比传感器检测到的排气空燃比之前的略微偏空燃比设定达到稀空燃比,然后将目标空燃比变为浓 由下游侧空燃比传感器检测到的排气空燃比达到稀空燃比时的空燃比设定,然后将目标空燃比设定为稍高的空燃比设定 由下游侧空燃比传感器检测到的排气空燃比达到浓空燃比。

    • A coupling ring is provided, including a series of unit members with adjacent unit members rotatably coupled to each other, and a fastener coupling unit members on both ends to each other. A concave groove provided to extend circumferentially is externally fitted into an outer circumference of each of two opposing flanges. The unit members on the both ends are coupled to each other by the fastener to be turned into an annular state. The fastener is fastened to thereby press an inclined surface. The flanges are pressure-bonded to each other by forces generated during pressing. A stopper member is provided to restrict a separation angle between the unit member on one end and an adjacent unit member to fall within a certain angle in an open state in which the unit members on the both ends are not coupled to each other provided on at least one of the unit members.
    • 提供了一个联接环,包括一系列具有可相互连接的相邻单元构件的单元构件,以及两端彼此之间的紧固件联接单元构件。 设置成周向延伸的凹槽外部装配到两个相对的凸缘中的每一个的外圆周中。 两端的单元构件通过紧固件彼此联接以变成环形状态。 紧固件被紧固从而按压倾斜表面。 凸缘通过在压制过程中产生的力相互压合。 设置止动构件以限制一端上的单元构件与相邻单元构件之间的分离角度,使其在两端的单元构件彼此不联接的打开状态下落入一定角度 至少有一个单位成员。
