  • Hydrocarbon adsorption method and device for controlling evaporative emissions from the fuel storage system of motor vehicles
    Patent number: 7753034
    Abstract: The present invention is directed to an evaporative emissions control apparatus for minimizing fuel vapor emissions from a fuel storage system in a vehicle with an internal combustion engine. More specifically, the present invention is directed to an evaporative emissions control apparatus comprising a canister filled with a hydrocarbon adsorbent. The present invention is also directed an evaporative emissions control apparatus comprising a support substrate, which is coated with a hydrocarbon adsorbent slurry.
    Type: Grant

  • Hydrocarbon adsorption slurry washcoat formulation for use at low temperature
    Patent number: 7540904
    Abstract: The present invention is directed to an improved hydrocarbon adsorbent slurry washcoat formulation, which can be used for controlling evaporative hydrocarbon emissions from a motor vehicle. More specifically, the present invention is directed to an improved slurry composition of the present invention comprises one or more hydrocarbon adsorbent materials, and an organic polymer binder containing an anionic dispersant and/or stabilizing pH. The binder is used to improve the adhesion of the hydrocarbon adsorbent to the surface of the fuel storage, fuel delivery, or air intake system component.

  • Coated screen adsorption unit for controlling evaporative hydrocarbon emissions
    Patent number: 7531029
    Abstract: A hydrocarbon adsorption unit for recovery of volatile hydrocarbons which emanate from several sources and which would otherwise be released into the atmosphere through the air cleaner of an automobile engine when the engine is shut off. The unit is positioned in the air intake system such that all air flowing through the engine passes through the unit. The unit comprises a housing having an air inlet and an air outlet. The housing contains a substrate and a volatile hydrocarbon adsorber material coated on the surface of the substrate. The adsorber material may be silica gel, a molecular sieve and/or activated carbon. The material further contains a binder that will cause the material to adhere to the surface of the substrate.

  • Hydrocarbon adsorption trap for controlling evaporative emissions from EGR valves
    Patent number: 7278410
    Abstract: The present invention is directed to the use of an improved hydrocarbon adsorbent coating for the treatment of exhaust emissions from a motor vehicle. More specifically, the hydrocarbon adsorbent of the present invention can be coated to any surface area of an exhaust gas recirculation system to trap hydrocarbon vapors before they can be released to the atmosphere.
