Abstract
A tunable intake manifold extends between a plenum and an intake of an internal combustion engine. A manifold housing defines an interior and a runner wall extending through the interior. A slider extends through the interior and slidably engages the manifold housing. The slider defines a slider wall cooperative with the runner wall to form a runner for transporting air therethrough. The runner defines a cross section. A drive assembly is operatively coupled between the manifold housing and the slider to move the slider transversely along the manifold housing to change the defined cross section of the runner such that the volume of air passing therethrough changes with the movement of the slider.
Claims25
A tunable intake manifold for directing a flow of air to an internal combustion engine, said tunable intake manifold comprising:
- a manifold housing defining an interior extending between a receiving end and a transmitting end, said manifold housing having a runner wall extending through said interior;
- a plenum coupled to said receiving end of said manifold housing and having an inner cavity in fluid communication with said interior of said manifold housing;
- a slider having a slider wall extending through said interior of said manifold housing, said slider wall cooperates with said runner wall to define a runner having a defined cross sectional area for transporting the flow of air therethrough, said slider slidably engaged with said manifold housing for moving said slider wall relative to said runner wall to selectively change said defined cross sectional area of said runner, such that the volume of air passing therethrough changes with said movement of said slider;
- and
- a conduit extending between said housing and said plenum for transporting a secondary flow of air to said runner with said selective change of said cross sectional area of said runner by said movement of said slider wall.
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 runner wall extending through said interior between receiving end and a transmitting end;
- a slider having a slider wall extending through said interior of said manifold housing, said slider wall cooperating with said runner wall to define a runner having a defined cross sectional area for transporting the flow of air therethrough, said slider slidably engaged with said manifold housing for moving said slider wall relative to said runner wall to selectively change said defined cross sectional area of said runner, such that the volume of air passing therethrough changes with said movement of said slider;
- and
- said transmitting end including a first intake port and a second intake port separated by a divider wall therebetween such that said slider wall is selectively positionable for alignment with said divider wall to prevent flow of said air through one of said intake ports.
