## Abstract

An integrated air intake system may include an integrated body formed by combining a cylinder head cover at the top of an engine with an air cleaner body at a side of the cylinder head cover, an air duct connected to a side of the air cleaner body to make a channel for air sucked from the outside into the air cleaner body, an upper cover combined in contact with the air cleaner body at the top thereof, an intake hose connected to a side of the upper cover to supply purified air to an engine intake port, and an intake filter disposed in a space formed in the air cleaner body and the upper cover to purify the air sucked from the outside.

## Claims

### Claim 1

An integrated air intake system comprising:
an integrated body formed by combining a cylinder head cover at the top of an engine with an air cleaner body at a side of the cylinder head cover;
an air duct connected to a side of the air cleaner body to make a channel for air sucked from the outside into the air cleaner body;
an upper cover combined in contact with the air cleaner body at the top thereof;
an intake hose connected to a side of the upper cover to supply purified air to an engine intake port; and
an intake filter disposed in a space formed in the air cleaner body and the upper cover to purify the air sucked from the outside.

### Claim 2 (depends on 1)

The integrated air intake system according to claim 1, wherein the cylinder head cover and the air cleaner body of the integrated boy are integrally formed by injection molding.

### Claim 3 (depends on 1)

The integrated air intake system according to claim 1, wherein the cylinder head cover and the air cleaner body of the integrated boy are monolithically formed by injection molding.

### Claim 4 (depends on 1)

The integrated air intake system according to claim 1, wherein the air cleaner body is integrally formed at a side of the cylinder head cover while extending toward a crankshaft.

### Claim 5 (depends on 1)

The integrated air intake system according to claim 1, wherein the air duct is disposed perpendicular to the crankshaft, at a side of the upper cover, and an intake port is formed at the side of the air cleaner body.

### Claim 6 (depends on 5)

The integrated air intake system according to claim 5, wherein the cylinder head cover, the air cleaner body and the air duct are disposed in series along a crankshaft while the upper cover is connected on top of the air cleaner body.

### Claim 7 (depends on 5)

The integrated air intake system according to claim 5, wherein the intake port opens upwards to receive the air duct downwards

### Claim 8 (depends on 5)

The integrated air intake system according to claim 5, wherein the air duct and a discharge port of the upper cover are disposed substantially in parallel, the intake hose being connected to the discharge port.

### Claim 9 (depends on 1)

The integrated air intake system according to claim 1, wherein the upper cover has the same cross-section as the air cleaner body to seal the air cleaner body, and a discharge port is formed at the side of the upper cover and connected with the intake hose.
