Abstract
A composite air intake manifold assembly 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 an inner shell formed from a polymer and disposed within the cavity. The insert in combination with the upper half shell and the lower half shell cooperate to define at least a pair of spaced apart generally cylindrical shaped 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 an air inlet side of a cylinder head of the internal combustion engine. Each of the runners includes a continuous uninterrupted weld joint along substantially an entire peripheral edge thereof to provide a sealed fluid path from the opened air intake end to the opened air inlet end of the runner and prevent air leakage between adjacent runners whereby a generally uniform air supply is maintained to each associated cylinder head of the internal combustion engine.
