US Patent:

8272365, Sep 25, 2012
Filed:

Dec 29, 2011
Appl. No.:

13/339735
Inventors:

Ralph Wayne Cunningham - Milan MI, US
Amey Y. Karnik - Dearborn MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02D 41/18
F02D 9/08
US Classification:

123403, 123389
Abstract:

An engine with two vacuum sources is disclosed. In one example, a valve position is adjusted when engine load is low and intake manifold pressure is low to arbitrate vacuum between the two vacuum sources. The approach may increase engine operating efficiency during at least some conditions.

US Patent:

8572961, Nov 5, 2013
Filed:

Jun 23, 2010
Appl. No.:

12/821996
Inventors:

Amey Y. Karnik - Dearborn MI, US
Julia Helen Buckland - Commerce Township MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02D 23/00
US Classification:

60602, 60600, 606052
Abstract:

Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02M 25/07
F02B 37/007
US Classification:

12356811, 606052
Abstract:

Various systems and methods are described for an exhaust gas recirculation (EGR) system coupled to an engine in a vehicle. One example method comprises, calculating an EGR mass flow from a difference between measurements of clean air mass flow and total mass flow, and correcting for a transient mass flow error.

Filed:

Mar 17, 2011
Appl. No.:

13/050647
Inventors:

Amey Y. Karnik - Dearborn MI, US
Michael Joseph Zaitz - Dearborn MI, US
Julia Helen Buckland - Commerce TWP MI, US
Ralph Wayne Cunningham - Milan MI, US
Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
International Classification:

B60T 13/57
F15D 1/00
US Classification:

605471, 137 1
Abstract:

A vacuum pump onboard a vehicle provides vacuum for a brake booster and to control the electronic vacuum regulation valve (EVRV) valve of a wastegate on a turbocharger. Commands to the EVRV are based on an operating condition of an engine and the vacuum level in the vacuum system. In one example, a vacuum sensor is provided to determine vacuum proximate the EVRV. In another example, the vacuum proximate the EVRV is modeled based on the vacuum at the brake booster, which may be determined by a vacuum sensor coupled to the brake booster.

Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
International Classification:

F02B 37/18
US Classification:

60602
Abstract:

Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, the wastegate is adjusted according to a difference between the boost pressure and the atmospheric pressure. In this manner, the interdependency between controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration may be reduced.
