US Patent:

6932035, Aug 23, 2005
Filed:

Jan 28, 2005
Appl. No.:

10/905975
Inventors:

Fang Shui - Farmington Hills MI, US
Kim Ku - West Bloomfield MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F01L001/34
US Classification:

123 9016, 123 9015, 123 9039
Abstract:

A poppet valve operating system for an internal combustion engine includes a finger follower which is driven by an intermediate rocker. The intermediate rocker selectively converts motion imparted by a drive cam into either a purely translational trajectory, or into a mixed translational and rotational trajectory, so as to open a poppet valve which is ultimately actuated by a finger follower interposed between the intermediate rocker and the valve.

International Classification:

F16H 7/08
F16H 7/12
US Classification:

474111, 474110, 474109, 474134
Abstract:

A camshaft drive system for an internal combustion engine includes a drive sprocket fixed upon a crankshaft of the engine and a driven sprocket fixed upon a camshaft of the engine.

US Patent:

20130268179, Oct 10, 2013
Filed:

Apr 4, 2012
Appl. No.:

13/439742
Inventors:

Yan Wang - Ann Arbor MI, US
James Douglas Ervin - Novi MI, US
Kim Hwe Ku - West Bloomfield MI, US
Assignee:

Ford Global Technologies, LLC - Dearborn MI
International Classification:

F02D 28/00
F01L 1/34
US Classification:

701105, 123 9017
Abstract:

A method for controlling an electric variable cam timing (VCT) actuator is disclosed. The method includes during engine shutdown, adjusting camshaft position with an electric VCT actuator to a target starting location, applying a first current to the electric VCT actuator to maintain the target starting location, and during engine startup before camshaft position feedback becomes available, applying a second current to the electric VCT actuator to maintain the target starting location.

US Patent:

20130269315, Oct 17, 2013
Filed:

Apr 16, 2012
Appl. No.:

13/448215
Inventors:

James Douglas Ervin - Novi MI, US
Kim Hwe Ku - West Bloomfield MI, US
Gregory Patrick McConville - Ann Arbor MI, US
Brad Alan Boyer - Canton MI, US
Assignee:

FORD GLOBAL TECHNOLOGIES, LLC - Dearborn MI
International Classification:

F02B 27/04
F01L 1/04
US Classification:

60273, 123 906
Abstract:

Embodiments for routing exhaust in an engine are provided. In one example, an engine method comprises, during a first condition, firing a subset of cylinders and routing all exhaust from the subset of cylinders through a first exhaust manifold coupled directly to a catalyst and not a turbocharger, and during a second condition, firing all cylinders, routing a first portion of exhaust through a second exhaust manifold coupled to the turbocharger, and routing a second portion of exhaust through the first exhaust manifold. In this way, exhaust can be directly routed to a catalyst under some conditions.
