摘要： An exhaust manifold and related method have a hybrid clamshell construction including an outer manifold half stamped from a first metal and having a first wall thickness, as well as an inner manifold half stamped from a second metal that is different from the first metal and has a second wall thickness which is different from the first wall thickness. Opposite side edges of the outer and inner manifold halves are rigidly interconnected to define a hollow manifold bottom. Port and outlet flanges are rigidly attached to inlet and outlet sides of the manifold body.

摘要： A method for making catalytic converters with automated crack detection includes forming a rigid housing, providing a substrate shaped for reception in the housing, and forming a mat shaped to cover the exterior surface of the substrate and having a thickness which creates a tight friction fit between the substrate and the housing when the same are assembled. The mat is wrapped around the substrate, and the wrapped substrate is then stuffed into the housing using a reciprocating ram or the like that extends at a relatively constant speed. The stuffing force and the ram position are measured and recorded regularly to define an array of data. The data is analyzed for any abrupt changes in the stuffing force as a function of the ram position indicating a crack in the assembled substrate.

摘要： An exhaust gas treatment device for internal combustion engines and the like includes inlet and outlet end caps, two catalyst substrates, and a two-piece housing. A first, cylindrically-shaped housing member has a hollow interior in which one of the substrates is retained, a first end sealingly connected with the inlet end cap, and an opposite second end with a radially reduced section. A second cylindrically-shaped housing member has a hollow interior in which the other one of the substrates is retained, a first end sealingly connected with the outlet end cap, and an opposite second end with a radially enlarged section sized to receive therein the second end of the first housing member, whereby the reduced section of the first housing member and the enlarge section of the second housing member are spaced radially apart a predetermined distance to define an annularly-shaped space or gap which thermally insulates the associated portion of the exhaust gas treatment device.
