An inertia charge intake manifold is associated with an internal combustion engine having a plurality of cylinders. The intake manifold includes a plurality of elongated separate branch pipes each corresponding to a respective one of the cylinders. The intake manifold also includes a common flange for connecting a first end of each branch pipe to the internal combustion engine. The common flange has a first surface attached to the internal combustion engine. Further, the intake manifold includes a surge tank to which a second end of each branch pipe is connected. The common flange, the surge tank and each branch pipe are made of a hard thermoplastic synthetic resin. The common flange is integrally connected to the surge tank.

Inertia charge intake manifold for multi-cylinder internal combustion engine and connecting method for branch pipes of intake manifold

A synthetic resin-made intake manifold including a volumetric air-intake section communicating with an intake air supply source through an inlet pipe and a plurality of outlet pipes for connecting the volumetric air-intake section to cylinders of an internal combustion engine is fabricated by injection molding, by applying the die rotary injection method or die slide injection method, the volumetric air-intake section and the outlet pipes respectively, thereafter, assembling them together and joining into unity, so that a synthetic resin-made intake manifold adapted for efficient production and flexible designing or including outlet pipes of a complex shape is obtained.
