Patent number: 9683512Abstract: Systems and methods are provided for a high-pressure fuel pump to mitigate audible ticking noise associated with opening and closing of a digital inlet valve of the high-pressure pump. To reduce the ticking noise associated with the high-pressure pump when the engine is idling, a solution is needed that is simple and does not involve retrofitting the fuel system with noise, vibration, and harshness countermeasures to mask the noise. Pressure devices and associated operation methods are provided that involve adding a combination of several check valves, an accumulator, and a flow control valve with weep channels to allow the digital inlet valve to be deactivated during engine idling as defined by a threshold engine speed.Type: GrantFiled: May 23, 2014Date of Patent: June 20, 2017Assignee: Ford Global Technologies, LLCInventors: Mark L. Stickler, Vince Paul Solferino, Paul Zeng, Ross Dykstra Pursifull, Robin Ivo Lawther, Patrick Brostrom, Jacob Jensen, Christopher Woodring, Joseph F. Basmaji, Mark Meinhart, Gopichandra Surnilla

Patent number: 9169817Abstract: A method for operating a fuel pump is provided. The method may include decreasing a pump chamber pressure, passively opening a metering valve coupled to a pump chamber in response to the decreasing, and while the metering valve is open, generating a rotational output via a motor, transferring the rotational output into an actuation force applied to the metering valve via a metering valve actuation device, and inhibiting the metering valve from closing via sustaining application of the actuation force.Type: GrantFiled: December 5, 2012Date of Patent: October 27, 2015Assignee: Ford Global Technologies, LLCInventors: Paul Zeng, Vince Paul Solferino, Patrick Brostrom, Kyi Shiah, Joseph F.

Patent number: 9127605Abstract: A canister purge valve, fuel vapor recovery system, and method are provided. The canister purge valve may include an inlet port configured to be coupled with an inlet line to receive a fluid from a vapor-recovery canister. The canister purge valve may also include an outlet having two or more exit ports configured to be coupled with a common exit line to pass the fluid to an engine. In this way, improved mixing may be achieved without substantially increasing flow resistance and/or noise.Type: GrantFiled: March 21, 2012Date of Patent: September 8, 2015Assignee: Ford Global Technologies, LLCInventors: Kevin William Plymale, Paul Zeng, Patrick Brostrom, Abdelkrim Zouani, Ahsanul Karim

Patent number: 9016263Abstract: A high pressure fuel pump for use with an internal combustion engine and a method of operation of a high pressure fuel pump are disclosed. The high pressure fuel pump may include a supply chamber and a pump chamber separated by a passage in sealing arrangement with a disk. The disk may have one or more holes therethrough and be rotatable in order to place the holes in the disk in varying degrees of alignment with the passage to allow respective, varying amounts of fuel to flow through the passage.Type: GrantFiled: October 23, 2012Date of Patent: April 28, 2015Assignee: Ford Global Technologies, LLCInventors: Paul Zeng, Vince Paul Solferino, Patrick Brostrom, Kyi Shiah

Patent number: 8651090Abstract: A direct fuel injection cylinder for an engine of a vehicle includes a direct fuel injector disposed in an injector bore within a cylinder head. A beveled conical wave washer is disposed between a shelf in the injector bore and a shoulder of the direct fuel injector. During operation of the vehicle, the beveled conical wave washer is elastically deformed by radial displacement caused by absorption of high frequency energy from the direct fuel injector. Elastic deformation of the beveled conical wave washer may reduce noise which may be caused by impact of the direct fuel injector and the cylinder head.Type: GrantFiled: June 25, 2013Date of Patent: February 18, 2014Assignee: Ford Global Technologies, LLCInventors: Vince Paul Solferino, Paul Zeng, Patrick Brostrom, Giuseppe DeRose, Jr., Scott Lehto

Patent number: 8516996Abstract: A fuel injection system for an internal combustion engine includes a fuel injector pocket, formed within a cylinder head, for housing an injector which sprays fuel into a combustion chamber defined by the cylinder head and a piston crown. The injector is mounted with a conical isolator which is loaded at a lower, elastic rate during lower power operation, with the conical isolator being stacked solid between a tapered portion of the injector and a corresponding tapered portion of the cylinder head during high power operation of the engine and injection system. The isolator controls unwanted injector ticking noise, while protecting the integrity of the injector's tip seal by preventing excessive axial displacement of the injector during higher load operation.Type: GrantFiled: December 1, 2010Date of Patent: August 27, 2013Assignee: Ford Global TechnologiesInventors: Vince Paul Solferino, Paul Zeng, Scott Lehto, Patrick Brostrom, Giuseppe DeRose, Jr., Simon Antonov, Jim Chern
