Abstract:
An intake air flow divider insert is provided for use in an air intake duct connected to the intake end of an air intake manifold for an internal combustion engine, the manifold having a number, N, of intake air flow passages originating at the air intake end thereof, the number, N, being equal to at least two. The air flow divider insert device comprises an insert body having walls configured for smoothly dividing a single flow of intake air flowing through the duct and impinging on upstream regions of the device into a number, N, of air flows, wherein the number of air flows is equal to the number, N, of manifold intake air flow passages, the walls being configured for diverting each of said N air flows smoothly into a corresponding one of the manifold intake air passages when the insert is positioned in the air intake duct to be just upstream of the manifold when the duct is connected to the manifold. Peripheral edge regions of the insert device are configured for enabling the device to be fixed inside the air intake duct upstream adjacent the air intake manifold when the intake duct is connected to the inlet end of the manifold in its normal manner. When the number, N, is equal to two the insert device has a central web having a variable downstream width that substantially conforms to the spacing between the two air intake passages in the air intake manifold at the intake end thereof.
