US Classification:

422179, 422177, 422180

Abstract:

Disclosed herein is a method of making a catalytic converter; forming a shell having a welding deformation detail; inserting and housing a catalyst substrate inside the shell, wherein a mat support material is disposed between the shell and the catalyst substrate; welding an end cone having a flange to the shell by applying a deformation force to the flange causing deformation of welding deformation detail.

Assignee:

Tenneco Automotive Operating Company Inc. - Lake Forest IL

International Classification:

B21D 51/16

US Classification:

29890, 422179

Abstract:

A method is provided for installing a multi-layer mat () in an exhaust gas aftertreatment or acoustic device. The method includes the steps of wrapping the mat () around an inner surface of the device along the same plane for at least a complete wrap around the inner surface; subsequently wrapping the mat () around the already completed wrap such that each of the successive wraps of the mat () are offset a constant distance from the plane of the previous wrap; a final wrap of the mat () wherein the mat is wrapped along a final plane for at least a complete wrap around the catalyst; and installing the mat () in the device () after the wrapping steps.

Appl. No.:

8/929045

Inventors:

Roger Eugene Buck - Fenton MI
Dana Michael Serrels - Davison MI
Stephen Joe Myers - Owosso MI

Assignee:

General Motors Corporation - Detroit MI

International Classification:

B01D 534

US Classification:

422177

Abstract:

A housing for a catalytic converter for an automotive vehicle engine exhaust system is formed of two deep drawn shells having open inner ends welded together in generally abutting relation. Modified conical outer ends taper to reduced size openings for connection to associated exhaust system pipes. To permit deep drawing, the outer ends as seen in longitudinal cross section are formed with curved surfaces including an intermediate curvature replacing a conventional conical shape and defined by radii of a value between 0. 5 and 0. 8 times the inner diameter of the tubular body portions of the respective shells which enclose a catalytic element. Connecting radii are preferably not greater than 0. 1 times the tubular portion inner diameter. Various alternative forms of welded inner end joints are disclosed.

US Classification:

422168, 2989008, 34 80, 454284

Abstract:

An exhaust gas treatment device, which includes an outer layer, an inner layer that is at least in part disposed within the outer layer, and a loose-fill insulation disposed in the volume between the outer layer and the inner layer, where a piece of fiber mat is disposed between the outer layer and the inner layer and forms a barrier that at least partially prevents the loss of the loose-fill insulation from the volume between the outer layer and the inner layer and a manufacturing method that includes placing a loose-fill insulation into the volume of space between an inner layer and an outer layer and positioning a piece of fiber mat between the outer layer and the inner layer to form a barrier that at least partially prevents the loss of the loose-fill insulation from the volume of space between the outer and inner layers.
