Exhaust aftertreatment device, including chemical mixing and acoustic effects

Abstract:

An exhaust aftertreatment device (10) includes an aftertreatment element (24) for treating internal combustion engine exhaust, an injector (26) for injecting chemical species mixing with the exhaust prior to reaching the aftertreatment element, and a turbulator (36) turbulating the exhaust to enhance the noted mixing. In a desired combination, a two-stage integrated perforated tube combination structure includes a turbulent mixing tube (38) disposed in an acoustic tube (40) and concentrically surrounded thereby.

Abstract(Chinese):

排气后处理装置（10）包括用于处理内燃机排气的后处理元件（24），用于在到达后处理元件之前喷射与废气混合的化学物质的喷射器（26），以及使排气以增强所提及的混合。在期望的组合中，两级整体穿孔管组合结构包括设置在声管（40）中并同心地包围的湍流混合管（38）。
