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: An air cleaner for a vehicular engine includes a pre-filter which receives air flow containing particulates and a primary filter which receives the air from the pre-filter. The pre-filter removes a first proportion of particulates from the air, and the primary filter removes a second proportion of particulates from the air. The pre-filter is separately serviceable from the primary filter.

Abstract: The present invention is generally directed towards an air filter assembly in an air induction system in a motor vehicle. The air filter assembly comprises a housing and layered filter disposed in the housing. The air filter assembly provides for a sealing surface such that the air filter is sealed in the housing such that the filter can not removed without breaking the seal.

Abstract: A system 10 for analyzing a component such as an air filter. System 10 may be created by and/or comprise software which resides within a conventional computer aided engineering (“CAE”) system. The system 10 utilizes a CAE model 12 to analyze the functionality or performance of an air filter based on certain attributes of the filter, such as the size, shape and media of the filter, and/or to determine certain attributes of the filter, such as the size of the filter, based on certain desired performance requirements of the filter.

Abstract: The present invention relates to a hydrocarbon trap positioned in the air intake system of a vehicle, upstream from the engine and wholly in the airflow. The hydrocarbon trap comprises a holder and a material for adsorbing the hydrocarbons, inserted inside the holder. The holder comprises a screen that is added at the end facing the engine. The screen is held in place with the help of a locking mechanism. The locking mechanism comprises a locking ramp on the holder and corresponding locking tab on a clamping ring surrounding the holder.

Abstract: The present invention is generally directed towards an air induction system in a motor vehicle and more specifically to a methane storage device connectable to the air induction system. The methane storage device comprises a housing having an inner chamber. A reticulated material is located within the housing. The reticulated material is capable of trapping any hydrocarbon especially methane.

Abstract: An air induction filter assembly includes a housing and a plurality of filter layers disposed in the housing. One of the filter layers is a carbon impregnated polyurethane foam layer to remove residual hydrocarbon (HC) vapors diffusing through an air inlet to the filter.

Abstract: An air induction assembly 10 disposed in an intake passage through which air flows to an engine. The air induction assembly 10 has a conduit member 20 which defines an air flow path. A mass air flow sensor (MAFS) 30 is located in the intermediate conduit portion and is in fluid communication with the air flow path. The MAFS 30 being operative to generate an output signal corresponding to air flow rate within the intermediate conduit portion A plurality of flow conditioning elements (FCEs) 22 in the airflow path produce a uniform airflow with low turbulent fluctuations to the MAFS 30 under all vehicle and engine speeds without excessively restricting the air flowing to the engine.

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.
