US Patent:

8509983, Aug 13, 2013

Filed:

Nov 12, 2010

Appl. No.:

12/944798

Inventors:

Matthew King - Waterford MI, US
Rebecca J. Darr - Milford MI, US

Assignee:

GM Global Technology Operations LLC - Detroit MI

International Classification:

F01N 11/00

US Classification:

701 291, 60274

Abstract:

A method is provided for detecting a level of diesel-exhaust-fluid (DEF) in a reservoir that is operatively connected to a catalyst for a diesel engine. The method is employed in a vehicle in order to facilitate a refill of the reservoir. The method includes sensing a level of diesel fuel in a fuel tank via a sensor operatively connected to the tank. The method also includes determining whether the vehicle is on an incline using the sensed level of diesel fuel in the fuel tank. The method additionally includes determining the level of DEF in the reservoir if the vehicle is determined to be substantially not on an incline. A system is also provided for detecting a level of DEF in the reservoir.

Appl. No.:

12/251080

Inventors:

Matthew King - Waterford MI, US
Julian C. Tan - Canton MI, US

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS, INC. - DETROIT MI

International Classification:

F01N 3/00

US Classification:

60295, 60303

Abstract:

In accordance with exemplary embodiments, the present invention relates to systems and methods for regeneration of a filter, particularly a diesel particulate filter. In one exemplary embodiment, a method of regeneration of a particulate matter filter is provided. The method includes providing a heat source for regeneration of a particulate matter filter. The heat source is disposed proximate or upstream from the particulate matter filter. The method also includes activating the heat source to generate a first temperature profile of the heat source, the first temperature profile including a first temperature average. The method further includes increasing the temperature of the heat source to generate a second temperature profile of the heat source, the second temperature profile including a second temperature average, wherein the second temperature average is greater than the first temperature average.

International Classification:

F01N 3/00

US Classification:

60274

Abstract:

A method of controlling a vehicle includes determining if a diesel emission fluid is at least partially frozen, and determining if the vehicle is currently operating in a low diesel emission fluid inducement protocol. If the vehicle is not currently operating in the low diesel emission fluid inducement protocol, and the diesel emission fluid is at least partially frozen, then a temporary minimum diesel emission fluid mass may be defined to prevent entry of the vehicle into the low diesel emission fluid inducement protocol.

Appl. No.:

13/471672

Inventors:

Rebecca J. Darr - Milford MI, US
Paul Jasinkiewicz - Northville MI, US
Matthew King - Arden NC, US

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI

International Classification:

F01N 11/00

US Classification:

60274, 60295

Abstract:

A control method for an exhaust treatment system is provided. The method includes: selectively determining a fluid state from a plurality of fluid states based on a temperature of a fluid supply source; estimating an average consumption rate based on the fluid state; and evaluating a fluid supply within the fluid supply source based on the average consumption rate.
