Patent number: 10145277Abstract: An internal combustion engine for an automotive vehicle has an intake manifold receiving fresh air via an inlet duct. The engine includes a crankcase. A turbocharger is provided having a compressor with an inlet coupled to the inlet duct and an outlet coupled to the intake manifold. A first vent line couples the crankcase with the compressor inlet. A second vent line couples the crankcase with the compressor outlet and intake manifold. The second vent line has a valve blocking air flow into the crankcase and allowing air flow out from the crankcase. The first vent line comprises a dual-acting valve having a first flow capacity into the crankcase and a second flow capacity out from the crankcase which is greater than the first flow capacity. Thus, crankcase ventilation is optimized for both engine idle and high engine load conditions.Type: GrantFiled: July 10, 2017Date of Patent: December 4, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Christopher W. Newman, Roy A. Ford

Patent number: 9975500Abstract: An apparatus includes an engine assembly and an engine cover. The engine cover includes at least one through hole extending from a top surface to a bottom surface. An appliqué is mounted on the engine cover. The appliqué includes at least one mounting post extending through the at least one through hole. A backing plate is disposed on a bottom surface of the engine cover receiving the at least one mounting post to secure the appliqué to the engine cover.Type: GrantFiled: August 31, 2016Date of Patent: May 22, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Gary Nola, Christopher W. Newman

Patent number: 9909470Abstract: A crankcase ventilation system for a turbocharged engine has full bi-directional flow for an idle state and a boosted state. A PCV valve provides air flow from the crankcase to the intake manifold in the idle state. A restriction in a first vent line limits fresh air into the crankcase in the idle state. A PCV bypass permits a one-way flow into the crankcase via a second vent line bypassing the PCV valve in the boosted state. A pressure relief valve in communication with the first vent line is configured to bypass the restriction in the boosted state when a pressure in the crankcase exceeds a threshold pressure. In a preferred embodiment, the PCV bypass is configured to bypass both the PCV valve and a pull separator (i.e., oil separator at the second vent line) in the boosted state.Type: GrantFiled: April 23, 2015Date of Patent: March 6, 2018Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Adam M. Christian, Christopher W. Newman, Katherine Jane Randall

Patent number: 9840989Abstract: A cover for an engine assembly of a motor vehicle is attached at one end by a hinge and at the other end by sockets interlocking with engine projections. The engine assembly has a first hinge portion located at a top, rearward end of the engine assembly, and has first and second structural projections extending upwardly and spaced from the first hinge portion. The cover has a foam body overmolded onto a rigid substrate. The substrate has an integral second hinge portion to engage the first hinge portion. The foam body is formed of polyurethane foam with first and second sockets releasably receiving the first and second projections, respectively, to hold the cover at an installed position. The soft cover provides excellent noise and vibration performance together with a desired visual appearance. Manual installation and removal of the cover is done easily and without any tools or removable fasteners.Type: GrantFiled: November 30, 2015Date of Patent: December 12, 2017Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Christopher W. Newman, Christopher T. Snow

Publication number: 20170022947Abstract: An engine cover system for joining a cover with an intake manifold body. A plurality of structural ribs project from an external surface of the body including a pair of parallel ribs. Each parallel rib carries an integrally-molded U-shaped receiver strip extending transversely from the parallel ribs to form slots having closed ends proximate a first edge of the body and slot openings defined by respective edges of the receiver strips. The engine cover is comprised of a shroud, first and second radial arms, and first and second hinge pins projecting from the first and second radial arms, respectively. The hinge pins are configured to slide into the slots via the slot openings into the closed ends. First and second elastomeric ferrules are installed on the first and second hinge pins, respectively, configured to be compressed by the receiver strips when captured at the closed ends.Type: ApplicationFiled: July 21, 2015Publication date: January 26, 2017Inventors: Mike Hamzeh, Milind B.
