摘要： A catalytic converter includes a longitudinally disposed body portion having first and second shell halves and an interior through which the combustion product can flow. A manifold is provided for forming a passageway between the body interior containing a reducing catalyst and the body interior containing an oxidizing catalyst. The manifold includes first and second manifold halves, with each manifold half including a pair of flanges which extend perimetrally and substantially completely along the interior wall of one shell half. The manifold flanges are disposed substantially parallel to the interior wall and coupled thereto. The manifold flanges include a portion which is recessed inwardly from the interior wall and first and second mating sections. The recessed portions include air holes for introducing air into the passageway between the reducing catalyst and the oxidizing catalyst. The first mating section includes a stud and the second mating section includes an aperture sized and positioned to receive the stud of the first mating section. Each shell half also includes a portion of the interior wall for attaching the pair of manifold flanges to the interior wall of the shell. This portion has a greater longitudinal extent than the longitudinal extent of the pair of manifold flanges.

摘要： A catalytic converter includes a longitudinally disposed body portion having first and second shell halves and an interior in which first and second catalytic substrates are disposed. A divider is positioned between the first and second catalytic substrates and is selectively attachable to accommodate substrates of various relative sizes. The divider includes first and second divider halves, with each divider half having a pair of flanges which extend perimetrically and substantially completely along the interior wall of one shell half. The portion of the interior wall of each shell to which the divider flanges are attached has a greater longitudinal extent than the longitudinal extent of the pair of divider flanges to allow selective placement of the dividers in the converter body portion. The divider flanges are disposed substantially parallel to the interior wall and are coupled thereto. The divider flanges include a portion which is recessed inwardly from the interior wall. This portion provides a passageway between the substrates and first and second mating sections. The first mating section includes a stud and the second mating section includes an aperture. The aperture of the second mating section is sized and positioned to receive the stud of the first mating section.

摘要翻译： 催化转化器包括纵向设置的主体部分，其具有第一和第二半壳体以及设置有第一和第二催化基板的内部。 分隔件定位在第一和第二催化基板之间，并且可选择性地附接以容纳各种相对尺寸的基板。 分隔器包括第一和第二分隔器半部，每个分隔件半部具有一对凸缘，其沿一个壳体半部的内壁周向和基本上完全延伸。 分隔件凸缘所附接到的每个外壳的内壁的部分具有比一对分隔凸缘的纵向范围更大的纵向范围，以允许将分隔件选择性地放置在转换器主体部分中。 分隔件凸缘基本上平行于内壁设置并与其连接。 分隔凸缘包括从内壁向内凹入的部分。 该部分提供了基板与第一和第二配合部分之间的通道。 第一配合部分包括螺柱，第二配合部分包括孔。 第二配合部分的孔径的尺寸设置成接纳第一配合部分的螺柱。
