    Abstract: The present invention provides an intake manifold which can improve distribution of a drawn fluid among cylinders of an internal combustion engine without major changes. An intake manifold made of resin includes: an intake port 21 formed by welding together a base member 2 and a cover member 5 and adapted to take in outside air; a chamber 10 connected with the intake port 21 through a connecting passage 25 formed by including a cavity portion 50; and plural discharge ports 27 connected with one another through a branch passage branching from the chamber 10, wherein a shielding member 60 adapted to shield the cavity portion 50 and function as a wall surface of the connecting passage 25 is provided in the connecting passage 25.

    Abstract: An intake manifold made of synthetic resin includes first, second and third members stacked in sequence and welded to form the intake manifold; a collector extending inside the intake manifold in a direction of a line of cylinders, a part of wall of the collector being formed by the third member; a plurality of branch passages formed substantially by the first and second members and wound around an outer periphery of the collector; and a connector passage leading from the collector to an outer peripheral side of the branch passage. The first, second and third members are respectively provided with first, second and third cylinder portions that are coaxially arranged with each other in a position between adjacent two branch passages. The connector passage is formed by the first, second and third cylinder portions with the connector passage communicating with an inside space of the collector.

    Abstract: An intake manifold includes a surge tank and a plurality of inlet pipes extending from the surge tank. Of the inlet pipes, proximal portions of an adjacent pair of inlet pipes are integrated, for example, by being connected with a plate-like connecting portion. The proximal portions of the two adjacent inlet pipes are integrated with a side wall of the surge tank by a reinforcing rib. The reinforcing rib extends, for example, from the connecting portion to the side wall of the surge tank. The intake manifold may be formed by a lower half body and an upper half body, which are welded to each other by using welding margins provided in the half bodies. In this case, it is preferable that parts of each welding margin that are located to correspond to the proximal portions of the inlet pipes be wider than the remainder of the same welding margin.

    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。
