Intake manifold
First Claim
Patent Images
1. An intake manifold, comprising:
- a plastic shell defining an intake passage fluidically communicating with a runner configured to pass air flow to a combustion chamber, the runner having a substantially flat inner surface; and
one or more ribs disposed along and extending away from the inner surface and into the air flow, the ribs having a length extending along a portion of the inner surface in a direction substantially corresponding to a flow direction.

Abstract
Embodiments in accordance with the present disclosure may provide an intake manifold that may include a plastic shell defining an intake passage in fluidic communication with a runner configured to pass inlet air to a combustion chamber. The runner may have a substantially flat inner surface. The intake manifold may also include one or more ribs disposed along the inner surface. The one or more ribs may have a length extending along a portion of the inner surface in a direction substantially corresponding to a flow direction in order to reduce NVH while maintaining reducing overall volume of the manifold.

8. An intake manifold comprising:
-
two or more runners extending from an intake passage configured to pass intake air toward two or more respective combustion chambers along respective runner flow directions, the two or more runners including at least one exterior runner wall; and a rib formed on an interior surface of each exterior runner wall, each rib extending into the intake air passing through the runner and oriented in the respective runner flow directions. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A system for an intake manifold comprising:
-
a first formed piece including two or more first runner portions extending from an inlet, a first formed piece rib formed on an inside wall of each first runner portion; a second formed piece including; two or more second runner portions extending from the inlet, and two or more third runner portions extending from the inlet; each respective first and second runner portions configured to couple together to form respective two or more formed runners extending from the inlet, and configured such that an air flow passed through the formed runners will flow in a direction of each respective first formed piece rib and each first formed piece rib located between side walls of a same runner of the formed runners and extending away from each respective inside wall and into the air flow passed through the formed runners; a third formed piece including two or more fourth runner portions extending from the inlet, a third formed piece rib formed on an inside wall of each fourth runner portion; and each respective third and fourth runner portions configured to couple together to form respective two or more additional formed runners extending from the inlet, and configured such that an air flow passed through the formed additional runners will flow in a direction of each respective third formed piece rib and each third formed piece rib located between side walls of a same runner of the formed additional runners and extending away from each respective inside wall and into the air flow passed through the formed additional runners. - View Dependent Claims (17, 18, 19, 20)
