  • Patent number: 11458932
    Abstract: A sensor assembly includes a cylindrical sensor window defining an axis, and an annular member coupled to the sensor window and rotatable about the axis.

  • Patent number: 10969478
    Abstract: 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.

  • Patent number: 10773273
    Abstract: An annular nozzle assembly includes an inlet tube, an annular tube, at least three first spray nozzles, and a plurality of separating vanes. The annular tube connects to the inlet tube. The first spray nozzles are fixed to the annular tube and are directed to spray inwardly and in a first vertical direction and are equally spaced from each other. The separating vanes are disposed within the annular tube and extend along a length thereof and define a flow channel for each first spray nozzle.

  • Patent number: 10232703
    Abstract: 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.

  • Publication number: 20180038321
    Abstract: 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.

  • Patent number: 9518539
    Abstract: 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.
