20090272361 | Hydrocarbon Adsorption Filter for Air Intake System Evaporative Emission Control - 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. | 11-05-2009 |
20100180581 | DIESEL OXIDATION CATALYST COMPOSITE WITH LAYER STRUCTURE FOR CARBON MONOXIDE AND HYDROCARBON CONVERSION - 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. | 07-22-2010 |
20100186375 | Layered Diesel Oxidation Catalyst Composites - 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. | 07-29-2010 |
