Composite intake manifold assembly for an internal combustion engine and method for producing same

摘要

A composite air intake manifold assembly (10) adapted for use with an internal combustion engine includes an upper half shell (14) formed from a polymer, a lower half shell (18) formed from a polymer and joined to the upper half shell (16) to define a housing having an internal cavity, and a one piece inner shell formed from a polymer and disposed within the cavity. The one piece inner shell in combination with the upper half shell and the lower half shell cooperate to define at least a pair of spaced apart air intake runners. Each of the runners includes an opened air intake end adapted to receive atmospheric air, and an opened air inlet end adapted to be connected to an associated air inlet side of a cylinder head of the internal combustion engine.
