US Patent:

7124743, Oct 24, 2006
Filed:

Oct 22, 2004
Appl. No.:

10/904077
Inventors:

Frank Gonzales, Jr. - Garden City MI, US
Paul Mingo - Farmington Hills MI, US
Xiaoying Zhang - Dearborn Heights MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02M 51/00
US Classification:

123491, 701105
Abstract:

A system and method for controlling an internal combustion engine during starting use position sensor information in addition to cylinder combustion information to transition from simultaneous fueling to sequential fueling by selecting a cylinder to receive a first sequential fuel injection. Embodiments include a system and method for controlling a sequentially fueled port injected internal combustion engine that contingently select a cylinder to receive a first sequential fuel injection based on position information indicating that the cylinder received a simultaneous fuel injection during its intake stroke. Engine rotational speed is monitored to detect combustion and determine which cylinder fired first. A first sequential fueling pulse is provided to the contingently selected cylinder unless a preceding cylinder in the firing order fires first.

Mark Linenberg - Dearborn MI, US
Mike Scannell - New Boston MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02D 41/06
US Classification:

123491, 123480, 123494, 701104
Abstract:

A method for adjusting fuel injection, the method comprising during an engine start from a non-warmed-up condition, identifying a fuel quality of fuel supplied to the engine during said start based on a performance of said start, and after said start is completed and during a transient fueling condition, adjusting a fuel injection amount based on said identified fuel quality from said start.

Filed:

Jun 12, 2006
Appl. No.:

11/423682
Inventors:

Steve Magner - Farmington Hills MI, US
Xiaoying Zhang - Dearborn Heights MI, US
John Rollinger - Sterling Heights MI, US
Mrdjan Jankovic - Birmingham MI, US
Sue Wagers - Newport MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F01L 1/34
US Classification:

123 9015, 123348, 123491
Abstract:

An approach is provided for compensating engine fueling during starting conditions in which positive valve overlap is enabled early in the start. In one example, the valve timing is adjusted to increase positive overlap during cold starting conditions, and fuel adjustments are provided to compensate for the evaporation effects of the increased residual push-back.

Filed:

Apr 15, 2003
Appl. No.:

10/413876
Inventors:

Gang Song - Canton MI, US
Ilya Kolmanovsky - Ypsilanti MI, US
John Michelini - Sterling Heights MI, US
Alexander Gibson - Ann Arbor MI, US
Larry Hardy - Riverview MI, US
Michael Cullen - Northville MI, US

International Classification:

F01L009/04
F01L001/34
US Classification:

123/090110, 123/090150
Abstract:

An electronic valve actuation system and control method is described. The valve timing is changed between early and late intake valve closing depending on engine operating conditions. Further, valve timing is adjusted to control engine airflow or engine torque. Finally, air-fuel ratio is adjusted based on feedback from an exhaust gas oxygen sensor as well as an estimate of air, fuel, and residual exhausted from cylinders operating with late valve closing (after bottom dead center) timing.

US Patent:

61386421, Oct 31, 2000
Filed:

Sep 14, 1998
Appl. No.:

9/151240
Inventors:

Xiaoying Zhang - Dearborn Heights MI
Timothy William Foster - Northville MI
Patrick J. Curran - Farmington Hills MI
Ian Edington - Coventry, GB
Assignee:

Ford Global Technologies, Inc. - Dearborn MI
Jaguar Cars Limited - Coventry
International Classification:

F02M 5100
US Classification:

123478
Abstract:

A method and system for fuel rail compensation in a returnless electronic fuel pump arrangement provides modification of fuel pulsewidth based on measured or inferred rail temperature. The present invention applies fuel pulsewidth control modifiers to enlarge the fuel pulse to increase the quantity of fuel being delivered to at least one fuel injector to offset any drop in fuel density and injector performance caused by fuel rail temperature. The present invention generates these modifiers separate from a vehicle's normal fuel delivery system adaptive control process, thereby eliminating any unnecessary adaptive processing and limiting of adaptive control range.

Filed:

Jul 20, 2015
Appl. No.:

14/803853
Inventors:

- Dearborn MI, US
Xiaoying Zhang - Dearborn Heights MI, US
Daniel Dusa - West Blloomfield MI, US
Paul Hollar - Belleville MI, US
Ethan D. Sanborn - Saline MI, US
International Classification:

F02D 41/06
F02D 41/26
F02D 41/38
Abstract:

Methods and systems are provided for controlling fuel injectors for a fuel system configured to deliver fuel to an engine via each of port fuel injection and direct fuel injection. In one example, a method may include, during an engine green start condition, injecting fuel with the port injector while not injecting fuel with the direct injector, and after the green start condition, injecting with each of the port injector and the direct fuel injector at a fuel ratio determined based on engine operating conditions.

Abstract:

Methods and systems are presented for adjusting an amount of fuel supplied to an engine via port and direct fuel injectors during transient engine operating conditions where the fuel injection amount is adjusted responsive to the transient engine operating conditions. In one example, a fuel injection amount is adjusted based on a time constant for a filter that is based on a direct fuel injection fuel fraction.
