Abstract: A high frequency attenuating device for an air flow induction system of a vehicle employing a thermoformed fibrous mat of any shape that fits robustly inside the duct. The dissipative nature of the fibrous mat helps in achieving broadband attenuation in the high frequency regime. The ability to manufacture the fibrous mat into any shape helps with restriction, targets different attenuation bands, and makes it more feasible to manufacture. Hybrid solutions are possible when combined with low frequency perforated silencers or high frequency QWT arrays injection molded onto them.

Abstract: Disclosed is an improved vehicle reservoir system for managing the distribution of applicable fluids, including either liquids or gases individually, simultaneously, or a combination of these in a predefined sequence. In one embodiment, a first reservoir contains a non-pressurized fluid that is transferred to a distribution manifold and a second reservoir contains a pressurized fluid that can be transferred to the distribution fluid for admixing with the first reservoir fluid, or to a second distribution manifold, or a combination thereof.

Abstract: Disclosed is a method to form arbitrarily shaped, uniform, lightweight, thermally insulating and acoustically absorptive automotive components with controllable density, thickness, porosity, and surface integrity. The method is based on natural cellulosic fibers such as those found in cardboard and paper and uses a thermoplastic fiber and particle slurry to form fusible components. The method produces components having the benefit of commercially available thermoformed fiber mats or open-cell extruded foam components with excellent acoustical properties, enhanced thermal insulation, and are light weight, which limits engine inefficiency, and the high cost of such parts so as to allow large scale implementation.

Abstract: Disclosed is an improved vehicle reservoir system employing a single pump with a fluid distribution manifold or linear valve. The manifold is fluidly coupled to the pump, drawing fluid from the reservoir for distribution through multiple outlet ports. In the primary embodiment, a pump would pressurize a cavity of the manifold and fluid would be released through solenoid operated valves located on each outlet port.

Abstract: In a vehicle with an internal combustion engine and a fuel vapor recovery system including a carbon canister connected to the fuel tank for collecting fuel vapors from the fuel tank as the tank is being refilled, an air filtering apparatus is provided to supply a flow of clean and dry purge air to the canister for the purging of vapors therefrom. The air filtering apparatus includes gradually spaced baffle means and filter element means and is remotely connected in the evaporative emission control system by hoses connected to the air inlet and air outlet of the canister.
