    • A device for treating a gas stream, especially an exhaust-gas stream of an internal combustion engine, includes at least one radial chamber radially conducting the gas stream and extending substantially radially from a central region to an outer collecting chamber. First and second, preferably parallel, substantially disk-shaped walls delimit the chamber. Electrodes project from the first wall into the chamber. The first wall is formed of electrically insulating material having the electrodes fastened therein and electrically interconnected by electrical conductors in or on the insulating material. Two or more chambers may be disposed, axially in series, around the central region. Very effective treatment of exhaust gas with an electric field for ionization or generating a plasma can be provided over a relatively short structural length in a flow direction. Electric fields running transversely to the flow direction provide new possibilities for selecting various parameters of the treatment device.
    • 用于处理气流,特别是内燃机的排气流的装置包括至少一个径向室,其径向地传导气流并且从中心区基本径向地延伸到外部收集腔。 第一和第二,优选地平行的大致圆盘状的壁限定了室。 电极从第一个墙壁进入室内。 第一壁由电绝缘材料形成,其电极被固定在其中,并且通过绝缘材料中或绝缘材料上的电导体进行电互连。 两个或更多个腔室可以围绕中心区域轴向地排列。 可以在流动方向上的较短结构长度上提供用于电离或产生等离子体的电场的废气的非常有效的处理。 横向于流动方向运行的电场为选择治疗装置的各种参数提供了新的可能性。
