摘要： An exhaust system for an engine having two groups of cylinders includes a small capacity catalytic converter disposed in an exhaust manifold for one group of cylinders and a larger capacity catalytic converter disposed in an exhaust manifold for another group of cylinders. The exhaust system also includes a primary catalytic converter, having a capacity larger than both the small and larger catalytic converters, disposed in an exhaust pipe commonly connected to the exhaust manifolds.

摘要： A catalyst carrier assembly for an automobile exhaust gas purifying device includes a smooth metal sheet and a pre-corrugated metal sheet wound alternately in a roll having a number of honeycomb convolutions. Each corrugation of the web-like pre-corrugated metal sheet is welded to the flat metal sheet at a plurality of points in the transverse direction during forming of the cylindrical roll. After forming the cylindrical roll, the cylindrical roll is heated so as to solder the web-like flat metal sheet and the web-like pre-corrugated metal sheet to each other at both of their end portions.

摘要： A layout structure of catalytic converters, used for an engine transversely arranged in an engine room formed in a front portion of a vehicle, includes a front catalytic converter connected to an exhaust manifold arranged in a forward direction of the vehicle with respect to the engine, and a rear catalytic converter connected to an exhaust manifold arranged in a backward direction of said vehicle, wherein the rear catalytic converter is arranged to be offset from a central position of the engine arranged along a widthwise direction of the vehicle by a predetermined distance. With this structure, the rear catalytic converter can be cooled in the same manner as the front catalytic converter. In addition, the rear catalytic converter is formed into a cylindrical member having an elliptic/oval cross-sectional shape with a major axis coinciding with a longitudinal direction of the vehicle, thus increasing the area of a heat-dissipating surface of the rear catalytic converter. With this structure, heat dissipation can be promoted, and cooling air can be quickly exhausted through a tunnel portion continuous with the engine room after a cooling operation.
摘要翻译：用于横向布置在形成于车辆前部的发动机室中的发动机的催化转化器的布置结构包括：前部催化转化器，其连接到相对于发动机沿车辆前方布置的排气歧管，以及连接到沿所述车辆的后退方向布置的排气歧管的后部催化转化器，其中所述后部催化转化器布置成从沿着所述车辆的宽度方向布置的所述发动机的中心位置偏移预定距离。利用这种结构，后催化转化器可以以与前催化转化器相同的方式被冷却。此外，后部催化转化器形成为具有椭圆形/椭圆形横截面形状的圆柱形构件，其长轴与车辆的纵向方向重合，从而增加后部催化转化器的散热表面的面积。通过这种结构，可以促进散热，并且在冷却操作之后，可以通过与发动机室连续的隧道部分快速排出冷却空气。
