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.
Claims20
A liquid storage system, comprising:
- a securely attached baffle with a plurality of openings;
- and
- an angled louver plate extending outward from the baffle arranged over one or more of the plurality of openings.
A fuel tank, comprising:
- a baffle integrally formed with a louver plate that is configured with an opening that allows fuel to flow therethrough.
A system, comprising:
- a vehicle powertrain with an internal combustion engine;
- a fuel storage tank for storing engine fuel, including a baffle formed in only one piece, a plurality of rectangular openings within the baffle for allowing a liquid flow, and a plurality of angled louver plates extending outward from the baffle with a louver length that is one of equal to and greater than a width of the rectangular opening, each angled louver plate positioned over an opening.
