    Abstract: An intake manifold for an internal combustion engine comprises upper and lower shell members with outer flanges. The shell members define a manifold cavity having a plenum and a plurality of runners. The upper shell includes an upper post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The lower shell includes a lower post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The terminus walls are attached to provide a brace across the plenum. One of the posts includes an orifice penetrating the tunnel wall. A sealed coupler extends from the one post and is adapted to receive a secondary gas for mixing within the plenum. Thus, secondary gases can be introduced without additional structures that could impede gas flow and could increase manufacturing cost.

    Abstract translation: 用于内燃机的进气歧管包括具有外凸缘的上壳体和下壳体构件。 壳体构件限定具有增压室和多个流道的歧管腔。 上壳体包括形成为具有隧道壁和终端壁的通气室中的凹陷的上柱塞。 下壳体包括形成为具有隧道壁和终端壁的压力通道的下部柱体。 连接终端墙以在整个通风室处提供支撑。 其中一个柱包括穿透隧道壁的孔。 密封的联接器从一个支柱延伸并且适于接收用于在增压室内混合的二次气体。 因此,可以引入二次气体而没有可能阻碍气体流动并且可能增加制造成本的附加结构。
