Patent number: 10969478Abstract: A system includes a base having a sensor opening. An object-detection sensor is aligned with the sensor opening. A motor and a guide are each supported by the base and are spaced from each other. A continuous band is flexible relative to and engaged with the motor and the guide. At least a portion of the continuous band is transparent and extends between the sensor and the sensor opening. If a contaminant, e.g., dirt, water, snow, etc., is on the continuous band at the sensor opening, the motor moves the continuous band to locate a clean section of the continuous band at the opening.Type: GrantFiled: January 3, 2018Date of Patent: April 6, 2021Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Dhaval P.

Patent number: 10232703Abstract: A system for reducing fuel slosh noise in a storage tank is described. In one particular example, the system comprises a slatted baffle with angularly arranged louvers extending therefrom to reduce sloshing noise in the tank by redirecting fuel waves while preventing surface wave collisions in the tank. In this way, the louvered baffle has the ability to provide different fuel flows based on the direction of flow incident on the slatted baffle, which may enhance the driving experience, particularly in hybrid and start-stop vehicles, where periods exist in the drive cycle where background engine noise is absent.Type: GrantFiled: October 6, 2014Date of Patent: March 19, 2019Assignee: Ford Global Technologies, LLCInventors: Dhaval P. Vaishnav, Maria Fernanda Maya Diaz, Mike Dong, Mohammad Usman

Publication number: 20180038321Abstract: Vapors in the fuel tank of a vehicle are collected in a carbon canister. An ejector or aspirator is used to purge the carbon canister in a pressure-charged engine in which a positive pressure exists in the intake. A compact ejector includes a substantially planar flange and a venturi tube coupled to the flange with a central axis of the venturi tube substantially parallel to the flange. By mounting the ejector on an intake component, having the venturi tube on the inside of the intake component, and having the venturi tube parallel to the flange yields a very compact package and protects the ejector from damage from other engine components.Type: ApplicationFiled: August 2, 2016Publication date: February 8, 2018Inventors: Chris A. Myers, Dhaval P. Vaishnav, Syed K. Ali, David S. Moyer, Scott M. Rollins, Matthew Werner, Eric A. Macke, Roger Joseph Khami

Patent number: 9518539Abstract: A method, comprising: purging fuel vapors from a fuel vapor canister and/or a fuel vapor bleed element to an engine intake with air routed through a transmission bellhousing. In this way, purge air may be warmed by heat generated in the transmission bellhousing during engine operation, thereby increasing desorption efficiency and reducing bleed emissions. Further, purge air may be pressurized in the transmission bellhousing to allow purging operations irrespective of intake manifold vacuum.Type: GrantFiled: May 12, 2014Date of Patent: December 13, 2016Assignee: Ford Global Technologies, LLCInventors: Niels Christopher Kragh, Mark W. Peters, Donald Ignasiak, Mike Dong, Dhaval P. Vaishnav
