US Patent:

7797929, Sep 21, 2010
Filed:

May 21, 2007
Appl. No.:

11/751414
Inventors:

Shane Elwart - Ypsilanti MI, US
Jason Aaron Lupescu - Ypsilanti MI, US
Joseph Robert Theis - Rockwood MI, US
Gopichandra Surnilla - West Bloomfield MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02B 27/04
F01N 3/00
F01N 3/10
US Classification:

60295, 60273, 60285, 60286, 60301
Abstract:

A method of controlling an engine having a lean NOx trap in the exhaust is described. The method comprises during a first mode, at a first temperature, storing NOx at a lean condition and then purging stored NOx from the NOx trap at a rich condition without concurrently supplying oxygen to the trap during the purging and during a second mode, at a second, lower temperature, storing NOx at a lean condition and then purging stored NOx from the NOx, where an exothermic reaction is generated to temporarily raise the temperature of the trap by supplying oxygen and reductants with an overall rich mixture to the trap during the purging.

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02B 47/08
F02B 47/10
US Classification:

1235682, 701108
Abstract:

Systems and methods are provided for operating an engine exhaust system. In one example, a system comprises a first valve, and a second valve coupled to the first valve via a shaft. A first position of the shaft situates the first valve closed and the second valve open, a second position situates the second valve closed and the first valve open by a first amount, and a third position situates the second valve closed and the first valve open by a second, larger amount.

Filed:

Mar 3, 2009
Appl. No.:

12/396782
Inventors:

Michael James Uhrich - West Bloomfield MI, US
Stephen B. Smith - Livonia MI, US
James Michael Kerns - Trenton MI, US
Shane Elwart - Ypsilanti MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F01N 3/00
US Classification:

60287, 60281, 60284
Abstract:

Methods and systems are provided for operating an engine having a hydrocarbon retaining system and an emission control device coupled to an engine exhaust, the engine exhaust comprising a venturi. One example method comprises, during a storing condition, routing exhaust gas through the venturi without generating a venturi action, and then to the hydrocarbon retaining system, while bypassing the emission control device, to store hydrocarbons in the hydrocarbon retaining system, and during a purging condition, routing exhaust gas through the venturi while generating venturi action, then to the emission control device, and then to the hydrocarbon retaining system, to purge stored hydrocarbons, wherein a flow of purged hydrocarbons is drawn back to the venturi via venturi action.
