摘要： An intake manifold for multicylinder, in-line type engine wherein a distribution chamber extends along the engine and a separate intake pipe extends from the distribution chamber to each intake port for each engine cylinder. When the engine has an oval intake port, usually because of two intake valves, with the major axis extending the length of the engine, the intake pipes have matching oval openings. The connection between each intake pipe and the distribution chamber is oval in shape but oriented with the major axis extending laterally to reduce the length of the distribution chamber. The walls of the manifold vary in thickness for reducing weight and the moment of inertia by progressively decreasing the wall thickness in the direction away from the engine.
