摘要： PROBLEM TO BE SOLVED: To provide an exhaust device for a vehicle that can be easily constituted at low cost, can reduce pressure loss due to exhaust resistance, and can easily drain and remove water to outside an exhaust pipe.SOLUTION: An upper part of an exhaust pipe 11 comprises a vertical exhaust pipe part 14A on the side of an engine 2 and a bent exhaust pipe part 14B connected thereto tilting from an upper end of the vertical exhaust pipe part backward and upward, and a backward exhaust port 15 is formed in the bent exhaust pipe part. A cylindrical member 21 is fitted around the bent exhaust pipe part with a gap S interposed, and a return part 28 is formed inward from an external end edge 27a of the cylindrical member. The return part is located outside the backward exhaust port, and an upper-end opening part 31 formed of its inner edge part is formed in a similar shape smaller than the backward exhaust port. Since no other body is present as exhaust resistance on an inner surface of the exhaust pipe, exhaust gas can be discharged powerfully in a pressure loss reduced state. The majority of drops of water come into contact with the return part and can be prevented from scattering from an upper-end opening part, and the drops of water fall along an external surface of the exhaust pipe, so that water can be easily drained to outside the exhaust pipe and removed.
摘要翻译：要解决的问题：为了提供一种可以容易地以低成本构成的车辆的排气装置，可以减少由于排气阻力引起的压力损失，并且可以容易地排放并排出排水管外部的水。解决方案：上部排气管11包括在发动机2侧的垂直排气管部14A和从其垂直排气管部的上端向上后方倾斜地连接的弯曲排气管部14B，形成有后排气口15 在弯曲的排气管部分。圆筒部件21插入弯曲的排气管部分周围，插入间隙S，并且从圆柱形部件的外部端部边缘27a向内形成有返回部分28。返回部位于后排气口的外侧，由其内缘部形成的上端开口部31形成为比后排气口小的形状。由于在排气管的内表面上不存在作为排气阻力的其他物体，所以排气能够在压力损失降低状态下强力排出。大部分水滴与返回部件接触，可防止从上端开口部分飞散，水滴沿着排气管的外表面落下，能够容易地将水排出至在排气管外面拆下。

摘要： A catalyst degradation detection device, determines whether a three-way catalyst has degraded on the basis of the maximum value of the amount of oxygen stored by the catalyst. When determining whether the three-way catalyst has degraded, the amount of stored oxygen is calculated, and the responsiveness of change in the output signal of an oxygen sensor to oxygen concentration change in catalyst-downstream exhaust is measured. Then, on the basis of the responsiveness of the oxygen sensor which measured the oxygen storage amount, the oxygen storage amount is corrected by reducing the same such that the worsened the measured responsiveness relative to a reference value, the greater the reduction in the oxygen storage amount used in determining whether the three-way catalyst has degraded. The corrected oxygen storage amount used is prevented from deviating from the correct value on the basis of a worsening of the responsiveness of the oxygen sensor.
