Controlling Spark Of An Engine With Adjustable Intake Valve Timing

View page
US Patent:
7107965, Sep 19, 2006
Filed:
Feb 2, 2006
Appl. No.:
11/345751
Inventors:
Michael Pozar - Cupertino CA, US
Robert Stein - Saline MI, US
Jeff C. Lyjak - Ann Arbor MI, US
Marcus W. Fried - Farmington Hills MI, US
Thomas G. Leone - Ypsilanti MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F02P 5/15
F02D 43/04
US Classification:
12340647, 12340655, 12340659, 60285
Abstract:
A system and method to control spark timing of an engine wherein the injection timing of the engine is varied relative to a crankshaft position depending on engine operating conditions. According to the method, spark timing is varied as fuel injection timing varies for at least a portion of the engine operating range. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.

US Patent:
7581528, Sep 1, 2009
Filed:
Mar 17, 2006
Appl. No.:
11/378671
Inventors:
Robert A. Stein - Saline MI, US
Thomas G. Leone - Ypsilanti MI, US
Jeff Lyjak - Ann Arbor MI, US
Michael Shelby - Dearborn Heights MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F02M 25/14
US Classification:
123431, 123575, 12340631, 123304
Abstract:
A system for an engine, comprising a cylinder, a first injection subsystem for injecting a first substance into the cylinder, a second injection subsystem for injecting a second substance into the cylinder, and an electronic engine controller configured to control a plurality of operating parameters of the engine, where the electronic engine controller is configured to cause variation of at least one of the operating parameters in response to a shortfall condition of the second injection subsystem.

Hydraulic Lash Adjuster With Damping Device

View page
US Patent:
7845327, Dec 7, 2010
Filed:
Aug 19, 2007
Appl. No.:
11/840981
Inventors:
Kevin V. Tallio - Saline MI, US
Jeff Chester Lyjak - Ann Arbor MI, US
Floyd Melvin Comer - Carleton MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
F01L 1/14
US Classification:
123 9052, 123 9055, 74569
Abstract:
A system and method for lash adjustment in the valvetrain of an internal combustion engine include a hydraulic lash adjuster having a damping device to limit rate of movement of a plunger relative to a body to control response time of the lash adjuster reducing or eliminating over-compensation or pump-up of the lash adjuster.

System For Improving Engine Performance And Emissions

View page
US Patent:
8417439, Apr 9, 2013
Filed:
Jul 2, 2010
Appl. No.:
12/830112
Inventors:
Adam Michael Christian - Garden City MI, US
Jeff Chester Lyjak - Ann Arbor MI, US
Beth Ann Dalrymple - Livonia MI, US
Assignee:
Ford Global Technologies, LLC - Dearborn MI
International Classification:
G06F 19/00
US Classification:
701112, 123 547, 60313
Abstract:
A system for improving engine performance and emissions is presented. The system can lower exhaust pressure and improve engine breathing. In one example, exhaust gases are combined to reduce exhaust pressure during exhaust valve overlap.

Controlling An Engine With Adjustable Intake Valve Timing

View page
US Patent:
20060037306, Feb 23, 2006
Filed:
Aug 18, 2004
Appl. No.:
10/920690
Inventors:
Michael Pozar - Cupertino CA, US
Robert Stein - Saline MI, US
Jeff Lyjak - Ann Arbor MI, US
Marcus Fried - Farmington Hills MI, US
Thomas Leone - Ypsilanti MI, US
International Classification:
F01N 9/00
F02D 41/34
F02D 43/00
US Classification:
060285000, 123478000, 123406470
Abstract:
A system and method to control an engine wherein at least intake valve timing is retarded relative to a crankshaft position depending on engine operating conditions. According to the method, at least a portion of the fuel is injected during the intake valve open period with retarded valve timing. The method can reduce fuel consumption, reduce transient fuel requirements, improve engine performance, and reduce CO emissions, at least under some conditions.
