Abstract: Provided are diesel exhaust components where palladium is segregated from a molecular sieve, specifically a zeolite, in a catalytic material. In the catalytic material, therefore, there are at least two layers: a palladium-containing layer that is substantially free of a molecular sieve and a hydrocarbon trap layer that comprises at least one molecular sieve and is substantially free of palladium. The palladium is provided on a high surface area, porous refractory metal oxide support. The catalytic material can further comprise a platinum component, where a minor amount of the platinum component is in the hydrocarbon trap layer, and a majority amount of the platinum component is in the palladium-containing layer. Systems and methods of using the same are also provided.

Abstract: Provided is a catalyst composition, in particular a diesel oxidation catalyst, for the treatment of exhaust gas emissions, such as the oxidation of unburned hydrocarbons (HC), and carbon monoxide (CO). More particularly, the present invention is directed to a catalyst structure comprising at least two, specifically three distinct layers, at least one of which contains an oxygen storage component (OSC) that is present in a layer separate from the majority of the platinum group metal (PGM) components, such as palladium and platinum.

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.

Abstract: The present invention is directed to the use of an improved hydrocarbon adsorbent coating for the treatment of evaporative emissions from a motor vehicle. More specifically, one or more hydrocarbon adsorbents, in accordance with the present invention, can be coated to any surface area of an air intake system to trap hydrocarbon vapors before they can escape to the atmosphere, through said air intake system. In another embodiment, one or more hydrocarbon adsorbents can be incorporated in the air filter of an air intake system.

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.

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.

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.

Abstract: A method for coating vehicular radiators with an ozone depleting manganese oxide catalyst in slurry form utilizes a robotic arm with multiple spray heads for spraying the face of the radiator. Each head is in fluid communication with its own dedicated peristaltic pump. The pumps are independently valved into and out of fluid communication with select heads as a function of the spray pattern effected by robotic arm movement.
