<p>An intake manifold assembly (10) is disclosed for an internal combustion engine (12). The intake manifold assembly (10) includes an intake manifold of a predetermined length and includes a plenum (70) having an interior wall surface and a predetermined cross-sectional area in a plane transverse to the length of the plenum. An air inlet (106) is located mid-way of the length of the plenum, and the air inlet (106) is generally circular in cross section. A plurality of outlet portions (104), each having an outlet port (82) in air flow communication with the plenum (70), each of the outlet ports (82) being substantially equally spaced along the length of said plenum. A cross-sectional area of the outlet port (82) of each outlet portion (104) is substantially equal to the cross-sectional flow area of the plenum (70) and of the air inlet portion (106). A diverter partition (72) extends integrally from the inner wall of the plenum (70) in a direction toward the mid-point of the air inlet (106) to divert incoming air flow and evenly distribute the air flow to each of the respective outlet ports (82).</p> |
