    • An apparatus for regenerating a filter trap (A) used to collect particulates from the exhaust gas of an internal combustion engine. The apparatus comprises: (a) apparatus (C-2) providing a flow of a heat transfer medium through the filter trap (A), (b) apparatus (C) for heating the heat transfer medium to a temperature effective to incinerate the particulates in the filter trap (A), and (c) a flow mask (22) stationed in the flow of heat transfer medium, upstream from said filter trap (A) effective to divert the heat transfer medium away from the radially inner zone of the filter trap (A) while guiding the heat transfer medium to engage and ignite the particulates along a radially outer region of the filter trap (A). The mask (22) is a circular disc and spaced upstream from the filter trap (A) effective to mask a central core area of the flow of heat transfer medium. The apparatus (C) for heating comprises one or more electrically heated resistance elements (21) arranged in a planar coil configuration extending transversely across the flow of heat transfer medium. A flow diffuser (23) is stationed upstream from the mask (22) and is comprised of a plurality of foraminous plates effective to diffuse and slow down the flow of heat transfer medium for increasing heat exchange. The flow diffuser (23) has a radiation reflective coating to limit heat losses and a member (24) is employed for depressing the temperature required to ignite the particulates.
    • 一种用于再生用于从内燃机的废气中收集微粒的过滤器捕集器(A)的装置。 该装置包括:(a)通过过滤器捕集器(A)提供传热介质的流动的装置(C-2),(b)用于将传热介质加热到有效焚烧颗粒的温度的装置(C) 在过滤器捕集器(A)中,和(c)位于传热介质流中的流量掩模(22),其位于所述过滤器捕集器(A)的上游,有效地将传热介质转移离开该传热介质的径向内部区域 过滤器捕集器(A),同时引导传热介质沿着过滤器捕集器(A)的径向外部区域接合和点燃微粒。 掩模(22)是圆盘,并且与过滤器捕集器(A)的上游隔开有效地掩蔽传热介质流的中心核心区域。 用于加热的装置(C)包括一个或多个电加热的电阻元件(21),其布置成横向横跨传热介质流动的平面线圈构型。 流动扩散器(23)驻留在掩模(22)的上游,并且包括有效地扩散和减慢传热介质的流动以增加热交换的多个有孔板。 流量扩散器(23)具有辐射反射涂层以限制热损失,并且使用构件(24)来降低点燃微粒所需的温度。
