Abstract

An intake system may include an intercooler configured to cool an air supplied to an engine, and an intake manifold configured to supply the air which is passed through the intercooler into at least one cylinder, and having a first runner and a second runner, in which the air which is exhausted from the intercooler is selectively supplied into at least one of the first runner and the second runner, and at least one cylinder which is communicated with the first runner is separated from at least one cylinder which is communicated with the second runner.

First claim

What is claimed is:

1. An intake system, comprising:
an intercooler configured to cool an air supplied to an engine;
a partition formed in the intercooler so as to separate an interior of the intercooler into two parts; and
an intake manifold configured to supply the air which is passed through the intercooler into at least one cylinder, and having a first runner connected to only a first one of the two parts and a second runner connected to only a second one of the two parts,
wherein the air which is exhausted from the intercooler is selectively supplied into at least one of the first runner and the second runner, and
wherein the air which is exhausted from the intercooler to the at least one cylinder via the first runner is separated from the air which is exhausted from the intercooler to at least one other cylinder via the second runner by the partition.

2. The intake system of claim 1 , wherein the intercooler is a water-cooling intercooler configured to cool the air by exchanging heat with coolant.

3. The intake system of claim 1 , further comprising:
an air control valve that is positioned at an upstream side of the intercooler and controls the air which is supplied into the intercooler; and
an air line that feeds the air into the air control valve, and supplies the air which is exhausted from the air control valve into the intake manifold.

4. The intake system of claim 3 , wherein the air control valve includes a control housing and a control board,
the control housing is configured to be disposed in an inner side of the air line so as to fix the control board, and
the control board is formed in a shape that the air is blocked to pass therethrough inside of the air line.

5. The intake system of claim 4 , wherein the control housing is formed in a ring shape, and
the control board is formed in a half circle shape.

6. The intake system of claim 4 , wherein when the control board is configured to revolve in a clockwise or an anticlockwise direction in order to change a position thereof, a first air line or a second air line is configured to be blocked selectively.

7. The intake system of claim 6 , further comprising:
a controller configured to control the control board in accordance with a rotation speed or an ignition order of the engine; and
a sensor device configured to send information of the rotation speed or the ignition order of the engine to the controller.

8. The intake system of claim 1 , wherein the first runner and the second runner are symmetric in a length direction of the air line, respectively.

9. The intake system of claim 1 , wherein the intercooler includes:
a first air line so as to be in fluid communication with the first runner;
a second air line so as to be in fluid communication with the second runner; and
wherein the partition is provided so as to separate air passing through the first air line and the second air line.

10. The intake system of claim 9 , wherein the air passing through an air control valve from an air line is configured to be supplied into the first air line or the second air line selectively.

11. The intake system of claim 10 , wherein the air control valve includes a control housing and a control board,
the control housing is configured to be disposed in an inner side of the air line so as to fix the control board, and
the control board is formed in a shape that the air is blocked to pass therethrough inside of the air line.

12. The intake system of claim 11 , wherein the control housing is formed in a ring shape, and the control board is formed in a half circle shape.

13. The intake system of claim 12 , wherein when the control board is configured to revolve in a clockwise or an anticlockwise direction in order to change a position thereof, the first air line or the second air line is configured to be blocked selectively.

14. The intake system of claim 13 , further comprising:
a controller configured to control the control board in accordance with a rotation speed or an ignition order of the engine; and
a sensor device configured to send information of the rotation speed or the ignition order of the engine to the controller.

15. The intake system of claim 14 , wherein the controller is configured to control the control board to be rotated so that the second air line is cut off, in accordance with when the rotation speed of the engine is lower than a predetermined speed and an ignition occurs in the at least one cylinder which is communicated with the first runner.

16. The intake system of claim 14 , wherein the controller is configured to control the control board to be rotated so that the first air line is cut off, in accordance with when the rotation speed of the engine is lower than a predetermined speed and an ignition occurs in the at least one cylinder which is communicated with the second runner.

17. The intake system of claim 14 , wherein the controller is configured to control the control board to be rotated so that the first air line and the second air line are opened, in accordance with when the rotation speed of the engine exceeds a predetermined speed.
