Patent number: 11629620Abstract: A cylinder head for an internal combustion engine includes a casting and plug. The casting defines a first channel, a second channel, and a bore extending inward from an exterior surface of the casting. The first channel intersects a central portion of the bore. The second channel intersects an opposing end of the bore relative to the exterior surface. The plug is disposed within the bore. The plug has a distal end that engages the casting along the opposing end of the bore via a slip-fit engagement, a proximal end that engages the casting within the bore proximal to the exterior surface via a fixed engagement, and an intermediate portion that is spaced apart from the casting along the central portion of the bore. The plug defines an internal channel that establishes fluid communication between the first and second channels.Type: GrantFiled: May 4, 2022Date of Patent: April 18, 2023Assignee: Ford Global Technologies, LLCInventors: Jeffrey D. Fluharty, Forest Heggie, Daniel Nelson, Jonathan Denis Crowe, David Henderlong, Richard J. Anton

Patent number: 9458744Abstract: An engine, such as a variable displacement engine, has a camshaft retainer. The camshaft retainer has a cap adapted to cooperate with a carrier to support first and second overhead camshafts for rotation. The retainer cap forms a housing for a camshaft journal bearing. The retainer cap also forms a retainer land defining an open channel adapted to provide a jet of lubricating fluid from the bearing housing to externally lubricate a cam. The retainer land is adapted to mate with a sealing land of the carrier to enclose the open channel.Type: GrantFiled: October 29, 2014Date of Patent: October 4, 2016Assignee: Ford Global Technologies, LLCInventors: Theodore Beyer, Forest Heggie, Jonathan Denis Crowe, Ramon Michael Lee, Murray Griffin

Patent number: 9086066Abstract: A rotary-vane vacuum pump comprises a stator and a vaned rotor, the stator partly defining an outlet chamber and including an outlet passage opening to the outlet chamber. The rotor is rotatably sealed to the stator; it has a sealing area to block the outlet passage, and, an unsealing area alignable with the outlet passage by rotation of the rotor to periodically unblock the outlet passage. The disclosed pump offers reduced resistance to lubricant oil discharge from the outlet passage, which results in lower differential pressure between inlet and outlet chambers at the end of the pumping cycle.Type: GrantFiled: February 27, 2013Date of Patent: July 21, 2015Assignee: Ford Global Technologies, LLCInventors: Mohammad Ali Moetakef, Steve Poe, Abdelkrim Zouani, Jonathan Denis Crowe

Patent number: 8733304Abstract: In one example, a method is described for an engine with a hydraulically actuated phaser for adjusting cam timing. The phaser is controlled by a hydraulic spool valve, for example, having a de-energized position that results in hydraulic force urging the phaser to a base timing. When it is desired to operate the cam timing at base timing, rather then leave the spool valve in a de-energized position that can generate leakage, the spool valve is adjusted to near a null position to reduce the hydraulic pressure drop across the cam journal and thus reduce oil leakage. In this way, it is possible to maintain base timing, while also reducing leakage.Type: GrantFiled: February 24, 2012Date of Patent: May 27, 2014Assignee: Ford Global Technologies, LLCInventors: Jonathan Denis Crowe, Jamie Charles Hanshaw
