    Abstract: A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate by a silicone binder producing high adsorption efficiencies while withstanding relatively high regenerative heat temperatures resulting from exhaust gas sensible heat. A hydrocarbon senses HC in the desorbed heated atmosphere stream to rotatively and sequentially index pie shaped, segmented portions of the wheel into the wheel's regenerative region while also functioning as the main component of an OBD device for the system.

    Abstract translation: 车辆气氛清洁系统利用具有延伸穿过涂覆有吸附剂的车轮的流动通道的再生轮。 大气流通过车轮的第一位置相关部分，其中包含HC的VOC被吸附，而加热的气流通过轮的第二位置依赖再生部分，VOC被解吸。 吸附剂是具有微孔尺寸的颗粒的活性炭，其通过具有高吸附效率的硅氧烷粘合剂附着到基材上，同时承受由废气显热导致的相对较高的再生热温度。 碳氢化合物感测解吸的加热气氛物流中的HC，以便将轮胎的饼形分段部分旋转并顺序地指向轮的再生区域，同时还用作系统的OBD装置的主要部件。

    Abstract: A stable, close-coupled catalyst, an article comprising the close-coupled catalyst and a related method of operation. The close-coupled catalyst comprises a catalyst support and a palladium catalytic component. Preferably and optionally, there are stabilizers including alkaline metal oxide, and rare earth metal components selected from the neodymium and lanthanum components. The close-coupled catalyst composition includes substantially no additional oxygen storage component such as praseodymium or cerium compounds. There is preferably a catalyst such as a three-way catalyst downstream of the close-coupled catalyst. The downstream catalyst preferably includes an oxygen storage component such as cerium oxide or praseodymium oxide.
