Patent number: 11187145Abstract: Methods and systems are provided for a branch communication valve in a twin turbocharger system. A branch communication valve may be positioned adjacent to a dividing wall separating a first scroll and a second scroll of the twin turbocharger. In an open position, the branch communication valve increases fluid communication between the first scroll and the second scroll and in a closed position, the branch communication valve decreases fluid communication between the first scroll and the second scroll.Type: GrantFiled: October 18, 2018Date of Patent: November 30, 2021Assignee: Ford Global Technologies, LLCInventors: Daniel Joseph Styles, Jack Adams, Keith Michael Plagens, Neal James Corey, David Born, Xiaogang Zhang

Patent number: 8347853Abstract: A method of forming a bowl in a top surface of a piston for an internal combustion engine includes machining the top surface of the piston to form a spherical depression in the top surface wherein the top surface comprises a dome prior to the machining and a center of the bowl is displaced from a center of the piston by at least one-quarter of a diameter of the piston. In one embodiment, the method includes machining recesses in the top surface aligned, respectively, with intake valves, an exhaust valve, and spark plug when installed. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.Type: GrantFiled: November 3, 2011Date of Patent: January 8, 2013Assignee: Ford Global Technologies, LLCInventors: Zheng Xu, Jianwen James Yi, Steven Wooldridge, David Bruce Reiche, Neal James Corey, Stephen George Russ, Steven Paul Penkevich, Claudia Olivia Iyer

Patent number: 8056531Abstract: A combustion system for a direct-injection, spark-ignition engine is disclosed. A side-mounted fuel injector located outboard the intake valves directs multiple fuel jets into a shallow, spherical bowl formed in a domed piston. Both good mixing to facilitate good air utilization with early injection and an ignitable mixture at the spark plug with late injection to facilitate cold start are provided with such a combustion system. Because the bowl is smooth and shallow, the surface area of the combustion chamber is less than with a deeper bowl of complicated shape. Lowering surface area in the combustion chamber leads to improved fuel economy.Type: GrantFiled: June 24, 2010Date of Patent: November 15, 2011Assignee: Ford Global Technologies LLCInventors: Zheng Xu, Jianwen James Yi, Steven Wooldridge, David Bruce Reiche, Neal James Corey, Stephen George Russ, Steven Paul Penkevich, Claudia Olivia Lyer

Patent number: 7980209Abstract: An internal combustion engine includes an electromagnetic valve actuator having an armature between upper and lower electromagnets with a stem extending through one electromagnet and guided by a bushing with increased clearance about at least a portion of the inner circumference in at least a middle portion of the bushing to reduce oil shear length and associated viscous friction in the actuator. A two-piece intake/exhaust valve guide includes a lower half with a stepped outer diameter cooperating with a counter-bored hole in the cylinder head to provide a positive stop. The upper and lower halves of the valve guide have increased clearance relative to the valve stem around at least a portion of the inner circumference to reduce oil shear length and associated viscous friction. Reducing viscous friction of the actuator and associated valve guide improves system robustness by decreasing the system sensitivity to temperature.Type: GrantFiled: May 20, 2008Date of Patent: July 19, 2011Assignee: Ford Global Technologies, LLCInventors: Philip Thomas Koneda, Thomas William Megli, Yan Wang, Neal James Corey

Patent number: 6446697Abstract: Method of rapidly making casting, comprising: designing a computer graphic model of the casting; sectioning the graphic model into graphic members which are at least one of blocks and slabs; carving a solid member for each of the graphic members, the solid members being (i) constituted of a meltable or evaporative solid material (i.e. wax or polystyrene), (ii) proportional to and enveloping its corresponding graphic member, and the carving being carried out by accessing two or more sides of each solid member to at least essentially duplicate the corresponding graphic member; forming a mold around the pattern, and casting metal within the mold while removing the pattern from such mold either by evaporation during pouring of the molten metal thereinto or by melting prior thereto.Type: GrantFiled: June 13, 1997Date of Patent: September 10, 2002Assignee: Ford Global Technologies, Inc.Inventors: Furqan Zafar Shaikh, Martin Andrew Brogley, Craig Edward Burch, Neal James Corey, Thomas John Heater, Gary Allan Vrsek
