    摘要： Particulates are removed from a particulate-laden gas stream such as the exhaust gas from an internal combustion engine by passing the gas through a cyclone type inertial separator. The separator has particulate reject slots cut in the side wall of the cyclone chamber through which particulates are rejected into a collection chamber. The collection chamber can be filled with a porous material such as wire mesh or expanded metal. The bottom of the cyclone chamber is a nonperforate plate. The separator can be built into a muffler. Performance is improved by including an agglomeration unit between the engine and the separator. The agglomeration unit comprises a housing inserted in the exhaust gas stream between the engine and the separator which contains a pervious mass of metal bodies such as wire mesh or expanded metal lath, or alternatively contains an alumina. Performance can be still further improved by placing a filter unit downstream from the separator.

    摘要： Embodiments of the present invention include methods and devices for trapping particulate matter suspended in exhaust from, for example, automotive diesel engines. Particulates carried in exhaust are actually a colloidal suspension of finely divided particulates in a fluid (in this case, the exhaust gases). This colloidal mixture is channeled through an open spiral exhaust channel. The particulates will differentially tend to travel through the fluid in a straight line, which leads them to collide with a fine mesh or porous material that defines the open spiral exhaust channel. The gas, on the other hand, will easily traverse the spirally shaped exhaust channel, with its molecules bouncing around the curved path of the spiral. Continuing through the device, more and more particulates will build up in the surrounding meshwork or porous material. In this manner, the device separates the particulates from the gas and leaves them lodged in the meshwork or porous material. Ultimately, the pipe will become clogged with the trapped particulates. By heating the device, the trapped particulates may be burned off and/or converted to CO2, which enables the device to be recycled and reused.

    摘要翻译： 本发明的实施例包括用于捕集悬浮在例如汽车柴油发动机的排气中的颗粒物质的方法和装置。 废气中携带的颗粒实际上是流体（在这种情况下为废气）中的细碎颗粒的胶体悬浮液。 该胶体混合物通过开放的螺旋排气通道引导。 颗粒将会以直线趋向于流过流体，这导致它们与限定开放螺旋排气通道的细网或多孔材料碰撞。 另一方面，气体将容易地穿过螺旋形的排气通道，其分子围绕螺旋的弯曲路径弹跳。 继续通过该装置，越来越多的颗粒将在周围的网状物或多孔材料中形成。 以这种方式，该装置将颗粒与气体分离并将其留在网状物或多孔材料中。 最终，管道将被捕获的颗粒堵塞。 通过加热该装置，被捕获的颗粒可被燃烧和/或转化成二氧化碳，这使装置能够被再循环和重复使用。

    摘要： This invention provides preforms of continuous glass fiber strands for use as the sound absorbing material in an engine exhaust muffler. Preferably, the material is made of glass fibers of E glass compositions. With this invention, the strands are fluffed up, not directly in the muffler, but in a cavity that is made of a perforated shell matching the muffler shape. During this operation, a powder binder also is blown in with the fibers. This blowing operation is completed by forcing hot air through the preform which melts or cures the binder and allows it to bond the fibers together.

    摘要： A reticulated tube of reinforced ceramic fibers is provided as a catalyst carrier for use in the catalytic conversion of internal combustion engine exhaust fumes. The tube is comprised of multiple layers of continuous yarn of selected ceramic fibers which can be bonded, if desired, with a substantially nonporous binder having selected properties and contained in a refractory oxide matrix having selected properties.
