DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention provides for an improved automobile air filter, or an aftermarket air filter component to improve the efficiency of the engine by creating a smoother, less turbulent air flow from the ambient air through the filter and into the engine. The air diverter is able to redirect the air once within an internal cavity of an air filter to create a more direct path for the air and reduce the turbulence of the air within the filter. This is advantageous because it improves the laminar conditions within the air filter, but also increase the air flow and air velocity based on the path created by the diverter. On the road this translates to more power with a smoother delivery as well as sharper throttle response since the airflow is not inhibited by abrupt geometry changes and so is more likely to remain laminar. The figures show the diverter installed on a filter, but may be installed on preexisting air filters.

[0017] FIG. 1 depicts an image of an air filter element, in accordance with a first embodiment. The air filter 100 is affixed to an upstream portion of air intake tubing. Filter element 100 has a top seal 102, may comprise a synthetic resin, such as a polyurethane resin, a filtration unit 103, a base sealing ring 104, may comprise a synthetic resin, such as a polyurethane resin. The filtration unit 103 defines an internal void 101. The filtration unit 103 may be generally or substantially oval in shape, for example, filter element 103 may resemble and oval shape and design. Filter element 103 may be adapted for filtering ambient air, and for providing an adequate volume, or flow rate, of filtered air to turbochargers and internal combustion engines.

[0018] With reference to FIGS. 2 and 3 are views of an intake filter 100. The intake filter 100 is comprised of a filter element 103, a base sealing ring 104, a top seal 102, and a diverter 106. The diverter 106 may be made from a flexible, rigid, or semi-rigid material based on the intended operation of the diverter 106, and the filter 100 design and requirements. The filter element 103, as seen from the top of filter element 103. Filter element 103 may include a top sealing 102 at a top portion 105 of filter element 103, and a base sealing ring 104 at a base portion 106 of filter element 103. Top sealing 102 and top portion 105 may be oval or substantially circular, provided than an internal void 101 is created. The base sealing ring 104 is designed to securely connect with an intake system of a vehicle or the engine of the vehicle based on the vehicle intake system design. Filter element 103 may have multiple filtration systems or layers based on the design. Placed within the internal void 101 is a diverter 106. The diverter 106 is designed to fit against the base sealing ring 104 and has a curved end 107 which extends a predetermined distance within the internal void 101 and has a substantially flat and thin design. The diverter 106, is attached or integrated into the base sealing ring 104 to form a substantially airtight seal between the diverter 106 and the base sealing ring 104. The diverter extends the entire width of the filter, creating two substantially equal sections within the internal void 101. The diverter 106, in the depicted embodiment is the same height as the filter element 103, to create to separate sections within the internal void 101. The diverter 106 has a substantially straight design, with an oversized base to accommodate the convex design. The curvature of the diverter 106 may be adjusted based on the filter 100 design, the idle air flow into the engine, and other environmental aspects that change with each engine design, the volume of air flow, and the speed of the air flow.

[0019] FIG. 4 is a longitudinal sectional view of the filter with the diverter 106, with arrows indicating the direction of flow of ambient or unfiltered air through the filter element 103 and interacting with the diverter 106. As the air enters the internal void 101, the air is redirected by the diverter 106 into the engine. Without the diverter 106, the air within the internal void 101 is extremely turbulence and has little direction. This sudden transition in geometry is detrimental for flow and results in wasted/lost power, efficiency of the engine, and the overall performance of the engine is reduced. With the addition of the diverter 106, the air entering the internal void 101 enters the air filter 100, but as the air is swirled around within the internal void 101, the air comes in contact with the diverter 106, which redirects the air towards the opening in the base sealing ring 104. The diverter 106 creates a smooth transition of the external air through the filter and into the engine. The laminar conditions throughout the intake with the diverter 106 is more efficient than previous designs. This smooth redirection based on the curved profile design of the diverter 106 improves the laminar conditions of the air within the internal void 101 and creates a more consistent and direct flow of air into the engine The curved end 107 of the diverter 106 is designed based on the intake filter 100 design to best improve the air flow based on the size and shape of the intake filter 100. The radius of the curved end, and the thickness of the diverter 106 are based on the filter 100 properties. In the depicted embodiment, the curved end 107 has a convex shape. In other embodiments the profile and curvature of the diverter 106 may be adjusted based on the filter 100 design and the air flow characteristics.

[0020] While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of this invention.

[0021] Providing filtered air to the internal combustion engine according to embodiments of the present invention may improve engine performance, for example, by increasing horsepower, torque, and/or fuel economy by creating a path of least resistance for the air.

[0022] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
