Abstract
An intake manifold system for an internal combustion engine includes inlet runners attached to a mounting flange. The inlet runners may be one piece with the mounting flange. A charge air control is mounted within the mounting flange, with the charge air control including a control shaft passage formed in the mounting flange, and a control shaft extending the length of the control shaft passage. The control shaft is journaled within the control shaft passage and carries a number of charge air control elements mounted for rotation with the control shaft.

11. An intake manifold system for an internal combustion engine, comprising:
-
a plurality of inlet runners for conducting charge air from a throttle body to a mounting flange; a throttle, mounted within said throttle body, for controlling the amount of charge air flowing through said inlet runners; a one-piece mounting flange connected to said inlet runners and having a cylinder head engaging surface; and a charge air control mounted within said mounting flange, with said charge air control comprising; a control shaft passage formed in said mounting flange, with said control shaft passage being configured as a channel extending along the length of the mounting flange and opening into said cylinder head engaging surface; a control shaft extending the length of said control shaft passage, with said control shaft journaled within the control shaft passage upon a plurality of bushings retained within apertures extending within said mounting flange from said control shaft passage to said cylinder head engaging surface; and a plurality of rotatable charge air control elements mounted to said control shaft; and a controller for rotatably positioning said control shaft and said charge air control elements to change a physical flow characteristic of charge air passing through said inlet runners and into intake ports configured within a cylinder head. - View Dependent Claims (12, 13, 14, 15, 16)
