Abstract:
1. A tunable intake manifold for directing a flow of air between a plenum and an internal combustion engine, said tunable intake manifold comprising: a manifold housing defining an interior, said manifold housing having a plurality of runner walls extending through said interior; a slider having a plurality of slider walls extending through said interior of said manifold housing, wherein said plurality of slider walls corresponds to said plurality of runner walls to define a plurality of runners, each of said plurality of runners having a defined cross sectional area for transporting the flow of air therethrough, said slider slidably engaged with said manifold housing for moving said plurality of slider walls relative to said plurality of runner walls to selectively change said defined cross sectional area of said plurality of runners while maintaining said plurality of runners at a fixed length, such that the volume of air passing therethrough changes with said movement of said slider, said slider including a platform slidably engaged with said manifold housing for movement of said slider relative to said manifold housing; and a drive assembly operatively connected between said manifold housing and said slider to move said slider relative to said manifold housing to change said defined cross sectional area of each of said plurality of runners such that the volume of air passing therethrough changes with said movement of said slider.
