摘要：A catalyst container for use in an exhaust manifold, which container includes perforated inner and outer cylinders and is positioned within the exhaust manifold, in the position of its exit, with catalysts filled in a cylindrical space defined between the inner cylinder and outer cylinder. In this catalyst container, annular openings in the cylindrical space at its top and bottom ends are covered with annular upper and lower lids, respectively, while a circular, inner cylinder lid is placed over the top opening of the inner cylinder to cover it. In addition, an outer cylinder lid is placed on the top circumferential edge of the outer cylinder in a manner to cover the top opening of the outer cylinder as well as the circular, inner cylinder lid. The catalysts are filled in a first space defined by the inner cylinder lid and the outer cylinder lid as well as in a second space defined between the outer cylinder and the inner cylinder. The first space communicates with the second space through at least one hole provided in the upper annular lid.
