Filed:

Dec 15, 2000

Appl. No.:

09/737844

Inventors:

Paul E. Jankowski - Goodrich MI, US
Stephen J. Myers - Owosso MI, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B01D053/34
F01N003/28

US Classification:

422179, 422176, 422177, 422180, 29890

Abstract:

A variable flow regulator assembly comprises a first stationary exhaust pipe, a second stationary exhaust pipe concentrically disposed within the first stationary exhaust pipe, and a movable exhaust pipe concentrically disposed between the first and second stationary exhaust pipes. The first stationary exhaust pipe includes one or more interference tabs concentrically and circumferentially fitted about its interior surface. The movable exhaust pipe includes one or more interference tabs concentrically and circumferentially fitted about its exterior surface. The interference tabs complimentarily interact and restrict the movement of the variable flow regulator so that the flow maldistribution of the exhaust gas stream entering the catalytic converter can be variably controlled.

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B01D053/34
F01N003/28

US Classification:

422179, 422177, 422180

Abstract:

A catalytic converter comprises a catalyst substrate concentrically disposed in a shell and having a mat support material located concentrically in between the catalyst substrate and shell. The catalyst substrate includes structural features located on its outer surface that engage the mat support material. The shear forces exerted between the catalyst substrate and mat support material, in addition to the normally present frictional forces, reduce the axial movement of the catalyst substrate during assembly and operation of the catalytic converter.

International Classification:

F01N003/00
F01N007/00

US Classification:

060/324000, 060/274000

Abstract:

A gas treatment system comprises a variable flow regulator assembly placed in operable and fluid communication with a shell of a gas treatment device. The variable flow regulator assembly comprises two or more conduit portions comprising a first portion and a second portion, wherein the second portion has a coefficient of thermal expansion greater than a first coefficient of thermal expansion of the first portion. The variable flow regulator assembly structurally changes shape to alter the flow maldistribution of an exhaust gas stream into the gas treatment device when light off is achieved.

Paul Jankowski - Goodrich MI, US

International Classification:

B01D 39/20

US Classification:

055523000

Abstract:

Disclosed herein are exhaust treatment devices and methods of manufacturing the same. In one embodiment, an exhaust treatment device can comprise: a substrate, a ring disposed about the substrate, and a retention material disposed between the ring and a formed shell. The formed shell can compress the retention material and restrict motion of the ring. The ring can have a portion extending from adjacent the substrate to adjacent the formed shell. In one embodiment, the method for manufacturing an exhaust treatment device can comprise: assembling a ring on a substrate, disposing a retention material in contact with the ring, on a side of the ring opposite the substrate, to form a substrate assembly, and disposing the substrate assembly within a formed shell.
