紧凑组合排气消声器和后处理元件以及聚水器的组件

Abstract

An ultra-compact combination exhaust muffler and aftertreatment element and water trap assembly provides exhaust flow through an aftertreatment element surrounded by an annular water collection space receiving water diverted and shed from an upper dome cap above the aftertreatment element and below the upper outlet. In a further embodiment, the assembly includes housing sections separable from each other at a service joint axially between axial ends of the aftertreatment element for ease of servicing. In a further aspect, the aftertreatment element has an axial end within a housing section saving axial extension space.
一种超紧凑组合排气消声器和后处理元件以及聚水器的组件使废气流动通过被环形水收集空间围绕的后处理元件,所述空间接收从位于后处理元件上方和上出口下方的上穹形盖转向和流出的水。在另外的实施例中,该组件包括外罩部分,其可在沿着轴向位于后处理元件的轴向端部之间的检修接合部处相互分离以便检修。在另外的方面中,该后处理元件具有位于外罩部分中的轴向端部,从而节约轴向延伸空间。
