Patent number: 9964058Abstract: Methods and systems for increasing fuel economy of a vehicle including a SCR catalyst are presented. In one example, an amount of EGR provided to an engine is decreased in response to performance of the SCR being within a predetermined range of performance. The methods and systems may increase vehicle fuel economy while vehicle tailpipe emissions are achieved.Type: GrantFiled: April 3, 2012Date of Patent: May 8, 2018Assignee: Ford Global Technologies, LLCInventors: Eric Kurtz, Paul Joseph Tennison, William Charles Ruona, Waheed Alashe, David A. May, Joshua Putman Styron

Patent number: 9175661Abstract: Methods and systems for operating a glow plug are disclosed. In one example, current supplied to a glow plug can be controlled to promote combustion stability of a cylinder after an engine start. Engine feedgas hydrocarbons may be reduced during conditions where combustion stability may be otherwise reduced to reduce tailpipe emissions.Type: GrantFiled: October 11, 2011Date of Patent: November 3, 2015Assignee: Ford Global Technologies, LLCInventors: Eric Kurtz, Paul Joseph Tennison, David A.

Patent number: 8166957Abstract: 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.Type: GrantFiled: June 28, 2011Date of Patent: May 1, 2012Assignee: Ford Global Technologies, LLCInventors: Jason Aaron Lupescu, Daniel Joseph Styles, James Michael Kerns, Michael James Uhrich, Stephen B.

Patent number: 4651796Abstract: An insulating window shade assembly includes a shade frame having a pair of vertical side channels open in a direction facing one another and designed to be mounted on the inside of the window to be insulated. A flexible insulating shade having inner and outer spaced apart parallel panels extends downwardly from the top of the channels, and the margins of the panels extend into the channels. Edge seals are provided in each channel made up of a pair of flexible polyester film strips with the adjacent sides of the strips being spring biased towards one another but being separable so that the margins of the shade panels may lie between them. The flexible character of the strips forms an effective insulating seal about the margins. A rerailer assembly is provided at the tops of the edge seals to guide the margins of the each panel between the strips of the edge seal should they become dislodged.Type: GrantFiled: October 22, 1984Date of Patent: March 24, 1987Assignee: Appropriate Technology CorporationInventors: Bruce C.

Patent number: 4418739Abstract: An insulating shade including a channel-type frame which is designed to be permanently installed on the prime window frame. The shade assembly which is mounted in the frame includes a pair of rollers which are geared together so as to rotate simultaneously and simultaneously either take up or play out the shade material. The rollers with the shade are supported on bearing plates which in turn are hung on spring brackets that snap into the channels permanently secured to the window frame. A cord operated pulley carries a gear which in turn drives the two rollers so as to raise and lower the shade. Weather stripping is secured inside the channels of the frame, which cooperate both with the sides of the shade itself and the weighted roller at the bottom of the shade to prevent cold air from flowing about the shade.Type: GrantFiled: January 15, 1982Date of Patent: December 6, 1983Assignee: Appropriate Technology CorporationInventors: James Woolnough, Bruce Gardner, David A.
