US Patent:

6983590, Jan 10, 2006
Filed:

Oct 22, 2002
Appl. No.:

10/277475
Inventors:

Matthew J. Roelle - Menlo Park CA, US
Martin L. Hall - Holly MI, US
Daniel H. Hooker - Livonia MI, US
Gary E. Johnston - Highland MI, US
Kevin E. Person - Highland MI, US
Jeffrey M. Polidan - Fenton MI, US
Assignee:

General Motors Corporation - Detroit MI
International Classification:

F01N 3/00
US Classification:

60289, 60274, 60277, 60290
Abstract:

A diagnostic system according to the present invention diagnoses system failure of a secondary air injection system. The secondary air injection system includes a pump that provides air to an exhaust system via a conduit and a valve that controls the flow of air through the conduit. A pressure sensor measures pressure in the conduit. A controller predicts pressure in the conduit during first, second and third operational phases of the secondary air injection system. The controller compares the measured pressure to the predicted pressure to evaluate operation of the secondary air injection system. During the first phase, the secondary air injection system is used to reduce vehicle emissions. During the second phase, the valve is shut while the pump is on. During the third phase, the pump is turned off while the valve is closed.

US Patent:

20100109214, May 6, 2010
Filed:

Nov 4, 2008
Appl. No.:

12/264343
Inventors:

Jeffrey M. Polidan - Fenton MI, US
Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - Detroit MI
International Classification:

F16L 5/00
F16F 13/14
B29C 69/00
US Classification:

26714013, 248 56, 264241
Abstract:

A pressurized fluid transport assembly includes a flexible component, such as a molded rubber component, that defines an interior passage through which the pressurized fluid flows. A sleeve surrounds at least a portion of the outer surface of the flexible component. The flexible component fits through an aperture in a support wall, such as a transmission casing, and has opposing first and second end portions configured to fit flush with a pressure source and a pressure destination when the component is through the aperture. The sleeve prevents expansion of the flexible component due to the pressurized fluid, such as expansion radially outward from the interior passage, but does not compromise the flexibility of the flexible component in a direction substantially parallel with the interior passage. A method of manufacturing the pressurized fluid transport assembly is also provided.

US Patent:

56063113, Feb 25, 1997
Filed:

Aug 30, 1995
Appl. No.:

8/521254
Inventors:

Jeffrey M. Polidan - Fenton MI
Dennis P. Stenson - West Bloomfield MI
Jacqueline A. Jolliffe - Midland MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

G08B 2100
US Classification:

340607
Abstract:

Significant restriction in an automotive internal combustion engine intake air filter is diagnosed over a wide range of engine operating conditions including low intake airflow rate conditions by qualifying transduced pressure drop across the air filter using airflow rate through the filter. A diagnostic count is maintained and updated in accord with detected significant restriction conditions. Adjustment values applied to the diagnostic count vary in accord with the degree of confidence associated with each detected significant restriction condition, such as indicated by varying engine intake airflow conditions.

US Patent:

52131785, May 25, 1993
Filed:

Apr 21, 1992
Appl. No.:

7/871528
Inventors:

Jeffrey M. Polidan - Fenton MI
Donald W. Harnack - Dearborn MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

B60K 2816
US Classification:

180197
Abstract:

The torque reduction of an internal combustion engine in response to an excessive acceleration spin condition is provided by a combination of disabling selected engine cylinders and spark retard. When a reduction of engine torque output is required in response to an excessive acceleration spin condition of the vehicle, the first level of torque reduction is provided at a level less than the torque reduction resulting from disabling a single cylinder of the engine by retarding the spark timing of the spark ignition in the cylinders. The amount of the retard of spark timing is such that the resulting torque reduction is less than the torque reduction resulting from disabling a single cylinder of the engine.

Filtered Check Valve Assembly

US Patent:

6105609, Aug 22, 2000
Filed:

Aug 13, 1999
Appl. No.:

9/373651
Inventors:

Jeffrey Michael Polidan - Fenton MI
David C. Shaw - Southgate MI
Phillip D. Hamelin - Warren MI
Assignee:

General Motors Corporation - Detroit MI
International Classification:

F16K 1514
US Classification:

1375157
Abstract:

A check valve assembly for an internal combustion engine includes a cup-shaped check valve housing having a cylindrical wall, an open end, and an upstream closed end, to define a chamber. An inlet passage extends through the closed end to introduce flow to the chamber. A filter assembly is received in the chamber, adjacent the upstream closed end of the check valve housing. A valve seat member is received in the chamber, downstream of the filter assembly, and has an annular ring slidingly received in the cylindrical wall and a valve seat extending radially inward from the annular ring with a central opening. A circular valve disk is oriented in the chamber, downstream of the valve seat member, and operates to close the central opening to prevent flow upstream through the check valve assembly and to flex allowing flow downstream through the central opening. A check valve cap is partially received within the housing to mate with the annular ring of the valve seat member and has a radial flange extending about an outer circumference. The flange provides a seating shoulder for the open end of the check valve housing.
