    Abstract: An air diffuser (20) for an air intake system of an internal combustion engine. The air intake system includes a throttle body (22) up stream from an intake manifold (24), with the air diffuser (20) mounted between them. The air diffuser (20) includes vanes (62,64) extending into its main bore (52) in order to diffuse and redirect the air flowing from the throttle body (22) into the intake manifold (24). An EGR assembly (70) is mounted to the manifold (24) just downstream of the inlet to the manifold (24). The diffusion and redirection of the air reduces the noise emanating from the intake manifold (24) for particular engine operating conditions, and also reduces the backflow of EGR gasses into the throttle body (22).

    Abstract translation: 一种用于内燃机的进气系统的空气扩散器（20）。 进气系统包括从进气歧管（24）向上游的节气门体（22），空气扩散器（20）安装在它们之间。 空气扩散器（20）包括延伸到其主孔（52）中的叶片（62,64），以便将从节气门体（22）流入进气歧管（24）的空气扩散和重定向。 EGR组件（70）刚好在歧管（24）的入口的下游安装到歧管（24）。 空气的扩散和重定向减少了用于特定发动机操作条件从进气歧管（24）发出的噪声，并且还减少了EGR气体回流到节流阀体（22）中的回流。
