US 2003/0079707 A1 · Composite intake manifold assembly for an internal combustion engine and method for producing same

Abstract

A composite air intake manifold assembly adapted for use with an internal combustion engine includes an upper half shell formed from a polymer, a lower half shell formed from a polymer and joined to the upper half shell 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. The method for producing the composite air intake manifold assembly includes the steps of: (a) providing an upper half shell formed from a polymer; (b) providing a lower half shell formed from a polymer; (c) providing a one piece inner shell formed from a polymer; (d) disposing the one piece inner shell in one of the lower half shell and the upper half shell; (e) subsequent to step (d), joining the one piece inner shell to the one of the lower half shell and the upper half shell; and (f) joining the one piece inner shell to the other one of the lower half shell and the upper half shell to thereby produce the composite air intake manifold assembly, wherein 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 including 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.
