Abstract

An intake air control apparatus for a vehicle may include a valve flap provided in an air intake passage, the valve flap having a rotation shaft facing opposite sides of the air intake passage, to control a cross-sectional area of air intake flow according to a rotation angle thereof about the rotation shaft; a driving device supplying a driving force to the valve flap; and a port plate being provided in the air intake passage, with a longitudinal direction thereof being in parallel to a longitudinal direction of the air intake passage, the port plate dividing the air intake passage into an upper passage and a lower passage, wherein based on a width direction, at least a portion of the port plate has a height changing portion that changes a height of the port plate from a lower internal wall of the air intake passage.

First claim

What is claimed is:

1. An intake air control apparatus for a vehicle, the apparatus comprising:
a valve flap provided in an intake air passage, the valve flap having a rotation shaft facing opposite sides of the air intake passage, to control a cross-sectional area of air intake flow according to a rotation angle thereof about the rotation shaft;
a driving device supplying a driving force to the valve flap; and
a port plate provided in the air intake passage, with a longitudinal direction of the port plate being in parallel to a longitudinal direction of the air intake passage, the port plate dividing the air intake passage into an upper passage and a lower passage, wherein based on a width direction of the port plate, at least a portion of the port plate has a height changing portion that changes a height of the port plate from a lower internal wall of the air intake passage
wherein the height changing portion is provided at a center portion based on the width direction of the port plate,
wherein the height includes a first height measured from the lower internal wall at a left side of the center portion of the port plate and a second height measured from the lower internal wall at a right side of the center portion of the port plate, the first height being different from the second height, and
wherein air flowing through left and right sides of the air intake passage, based on the height changing portion, has different cross-sectional areas at the left and right sides of the port plate, leading to asymmetry of air flow between the left and right sides of the air intake passage.

2. The intake air control apparatus of claim 1 , wherein
the valve flap is configured for controlling the air intake flow flowing into the lower passage by being rotated.

3. The intake air control apparatus of claim 1 , wherein
the port plate is configured such that the height changing portion has different thicknesses at left and right portions of the height changing portion.

4. The intake air control apparatus of claim 3 , wherein
the port plate is configured such that the height changing portion is provided at the center portion of the port plate to form a step that changes the height of the port plate discontinuously.

5. The intake air control apparatus of claim 1 , wherein
the port plate is configured such that the height changing portion is provided throughout the width direction of the port plate, wherein the height of the port plate changes throughout the width direction.

6. The intake air control apparatus of claim 5 , wherein
the port plate is configured such that the height thereof continuously changes along the width direction.

7. The intake air control apparatus of claim 6 , wherein
the port plate is configured such that the height thereof from the lower internal wall of the air intake passage changes continuously along the width direction.
