Abstract:
1. A system for controlling turbulence in a combustion engine having a composite upper intake manifold and a cylinder head, said system comprising: a composite housing including an open first end and an open second end and side walls spanning between said first and second ends, said open second end defining a first cross-sectional area, said sides walls having interior and exterior surfaces, said side walls including openings through opposite ones of said interior and exterior surfaces adjacent said second end, said first end being configured to be welded to the composite upper intake manifold and said second end having a gasket groove and said second end being configured to be connected with the cylinder head; a composite cartridge positioned within and removably joined with said second end of said composite housing, wherein the composite cartridge reduces said first cross-sectional area to define a second cross-sectional area, said composite cartridge further comprising: a body having surfaces interior to said composite housing, said body including holes through opposite ones of said surfaces interior to said composite housing; a flap valve having first and second ends and a middle portion therebetween that has a surface area that is less than said second cross-sectional area; and bushings joined with said first and second ends of said flap valve, said bushings having a central opening and said bushings being configured to rotate within said holes in said surfaces interior to said composite housing; a shaft including a first end that is inserted through said openings in said composite housing, said central opening in said bushings, and said holes in said surfaces interior to said composite housing, said shaft being rotatably and slidably connected to said flap valve within said composite housing, said shaft including a second end that protrudes from said composite housing; a radial gasket joined with said second end of said shaft; a lever arm joined with said second end of said shaft; and a press in place gasket positioned within said gasket groove in said second end of said composite housing.
