Embodiment Construction

[0016] refer to figure 1 , the intake manifold 10 has an upper housing member 11 and a lower housing member 12 defining a cavity 13 . Housing members 11 and 12 further define inlet 14 (inlet 14 receives the fuel / air mixture via the throttle body), plenum portion 15, and runner portion 16, wherein runner portion 16 has a plurality of runners for The air chambers are fluidly connected with corresponding engine cylinders (not shown). The upper housing member 11 and the lower housing member 12 are connected at a first outer flange 17 and a second outer flange 18 . Two struts 20 and 25 extend through the plenum portion of cavity 13 between housing members 11 and 12 to provide support to reduce vibration of manifold 10 .

[0017] The strut 20 has an upper strut portion 21 formed as a recess 22 recessed into the outer surface of the plenum portion 15 . The strut 20 has a lower strut portion 23 formed as a depression in an outer surface 24 of the lower housing member 12 . Flanges ...

Abstract

An intake manifold for an internal combustion engine comprises upper and lower shell members with outer flanges. The shell members define a manifold cavity having a plenum and a plurality of runners. The upper shell includes an upper post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The lower shell includes a lower post formed as an indentation into the plenum with a tunnel wall and a terminus wall. The terminus walls are attached to provide a brace across the plenum. One of the posts includes an orifice penetrating the tunnel wall. A sealed coupler extends from the one post and is adapted to receive a secondary gas for mixing within the plenum. Thus, secondary gases can be introduced without additional structures that could impede gas flow and could increase manufacturing cost.

Description

technical field [0001] The present invention relates generally to intake manifolds for combustion engines and, more particularly, to apparatus for introducing secondary gas into a primary fuel / air mixture passing through the intake manifold. Background technique [0002] Intake manifolds for internal combustion engines are typically formed from polymeric materials. In order to reduce the noise emanating from the surface of the intake manifold due to resonant frequencies arising at certain engine speeds, it is known to provide internal and external supports on the surface of the manifold and to provide internal struts formed of parent material. Internal struts traverse the plenum cavity within the manifold and are generally formed as recesses in the upper and lower housing members. Each depression has a channel wall and a terminus wall and penetrates the plenum cavity. The terminal walls of the upper and lower housing members are friction welded together while the outer fla...
