Abstract: Various embodiments relate to an air intake duct. The duct includes louvers forming an air inlet to a housing. Each louver includes an inlet section and an angled section, the angled section inclined with respect to the inlet section. The duct includes the housing positioned downstream of the louvers in an air flow direction. The housing includes a drain configured to permit separated water from an intake air passing through the louvers and into the housing to be drained from the housing. The duct includes an inner inlet duct that provides the intake air to a component. The inner inlet duct extends into the housing and positioned downstream of the louvers in the air flow direction. The inlet duct extends above the drain by a distance thereby forming a well in the housing between a top of the inner inlet duct and the drain.

Abstract translation: 各种实施例涉及进气管道。 导管包括形成到壳体的空气入口的百叶窗。 每个百叶窗包括入口部分和倾斜部分，倾斜部分相对于入口部分倾斜。 导管包括沿气流方向定位在百叶窗下游的壳体。 壳体包括排水口，其构造成允许分离的水从通过百叶窗的进气中进入壳体以从壳体排出。 管道包括将入口空气提供给部件的内部入口管道。 内部入口管道延伸到壳体中并且在空气流动方向上定位在百叶窗的下游。 入口管道在排水沟上方延伸一段距离，从而在内部入口管道的顶部和排水口之间在壳体中形成井。
