| 20080210189 | Intake Manifold Having Runners With Variable Cross Sectional Area - 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. | 09-04-2008 |

| 20080314352 | Edge-pivot charge-motion control valve system for an internal combustion engine manifold runner - An edge-pivot charge-motion control assembly for controlling air turbulence comprising a molded sleeve inserted into a runner port of an intake manifold of an internal combustion engine. A control valve element is pivotably mounted in the sleeve for external actuation.

| 20150040852 | SYSTEMS AND METHODS FOR MULTIPLE ASPIRATORS FOR A CONSTANT PUMP RATE - Methods and systems are provided for a parallel arrangement of at least two valved aspirators, with a high pressure source such as an intake throttle inlet coupled to a motive inlet of the arrangement and a low pressure sink such as an intake throttle outlet coupled to a mixed flow outlet of the arrangement. Intake throttle position and respective valves arranged in series with each aspirator of the arrangement are controlled based on intake manifold pressure and/or a desired engine air flow rate, for example such that a combined motive flow rate through the arrangement increases as intake manifold pressure increases. An intake throttle with a fully closed default position may be used in conjunction with the arrangement; during a fault condition where the intake throttle is fully closed, the valves of the arrangement may be controlled to achieve a controllable engine air flow rate during the fault condition. | 02-12-2015 |
