    • PROBLEM TO BE SOLVED: To provide an exhaust gas catalyst can and an exhaust system of a vehicle that prevent exhaust performance deterioration, improve low and medium speed performance, and have advantages in cost reduction and packaging.SOLUTION: An exhaust gas catalyst can and an exhaust system of a vehicle include a catalyst housed in the center of an inner space of the catalyst can, an inflow space and a discharge space respectively defined above and below the catalyst, an inflow-side partition wall vertically dividing the inflow space into a plurality of partial inflow spaces, and an exhaust gas inlet formed for each of the partial inflow spaces. A plurality of partitions vertically cross each other to form a plurality of through-holes in the partial inflow spaces of the inflow space. The through-holes are formed in a shape corresponding to an end shape of the catalyst.
    • 要解决的问题:提供一种防止排气性能恶化的车辆的废气催化剂罐和排气系统,提高低,中等速度性能,并且具有成本降低和包装的优点。解决方案:废气催化剂罐和 车辆的排气系统包括容纳在催化剂罐的内部空间的中心的催化剂,分别限定在催化剂上方和下方的流入空间和排出空间,将流入侧分隔壁垂直分割为多个 的部分流入空间,以及为每个部分流入空间形成的排气入口。 垂直交叉的多个隔板在流入空间的部分流入空间中形成多个通孔。 通孔形成为与催化剂的端部形状对应的形状。
