  • Intake manifold having runners with variable cross sectional area
    Patent number: 8516987
    Abstract: The present invention provides a tunable engine manifold which employs sliders to form one wall of the inlet runners. The sliders can be moved to alter the cross sectional area of the runners as desired. Seals on the sliders provide an efficient means to seal the runners to prevent undesired leaks within runners and, while not required by the present invention, the overmolding of the seals onto the sliders provides a cost effective and mechanically effective manner of providing the desired seals between the inlet runners and the sliders. The tunable engine manifold can be an inlet or an exhaust manifold and can provide a crossover between the banks of inlet runners, or between individual runners, to control resonance in the manifold.
