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.

Appl. No.:

10/267318

Inventors:

Jeffrey B. Hardesty - Byron MI, US
Paul E. Jankowski - Goodrich MI, US

Assignee:

Delphi Technologies, Inc. - Troy MI

International Classification:

B23P 17/00

US Classification:

2989008, 29445

Abstract:

An exhaust emission control device is manufactured by sizing a housing of over a substrate and intumescent mat subsequently to heating said emission control device. The step of heating causes said intumescent mat to at least reach a temperature at which it swells. If the substrate has a washcoat layer, it may be left unfired until after it is assembled with the housing, in which case the step of heating causes the washcoat layer to sinter.

International Classification:

F01N 3/00

US Classification:

60284, 60288, 60300, 60324

Abstract:

A variable flow regulator assembly includes 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.

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.
