## Abstract

A turbocharger fastening structure may include an exhaust manifold integrated head having two exhaust ports; a fastening unit located on one end portion of a turbocharger to be fastened to the exhaust manifold integrated head; and an intake hole formed on the fastening unit, corresponding to the two exhaust ports of the exhaust manifold integrated head, and having a rib, the intake hole allowing exhaust gas to enter the turbocharger through the exhaust manifold integrated head.

## Claims

### Claim 1

A turbocharger fastening structure comprising:
a fastening unit mounted on an end portion of a turbocharger and configured to be fastened to an exhaust manifold integrated head having two exhaust ports; and
an intake hole having a rib and formed on the fastening unit, corresponding to the two exhaust ports of the exhaust manifold integrated head,
wherein the intake hole is configured to allow exhaust gas to enter the turbocharger through the exhaust manifold integrated head,
wherein the rib extends in a longitudinal direction thereof inside an intake pipe along the intake pipe, and
wherein a ratio of a horizontal width of the rib to a length of the rib extending into the intake pipe ranges 1:1 to 1:1.2.

### Claim 2 (depends on 1)

The turbocharger fastening structure of claim 1,
wherein the rib includes a curved portion having a streamline shape on an end portion of the rib within the intake pipe.

### Claim 3 (depends on 1)

The turbocharger fastening structure of claim 1,
wherein the intake hole includes a first intake hole and a second intake hole divided by the rib.

### Claim 4 (depends on 1)

The turbocharger fastening structure of claim 1, further including:
a plurality of gaskets mounted on the fastening unit to conform to a shape of the intake hole.

### Claim 5 (depends on 4)

The turbocharger fastening structure of claim 4, further including:
at least one stopper positioned between predetermined gaskets among the plurality of gaskets.

### Claim 6 (depends on 5)

The turbocharger fastening structure of claim 5, wherein a center portion of each gasket of the plurality of gaskets is spaced with a gap from a corresponding stopper among the at least one stopper and is collapsible.

### Claim 7 (depends on 5)

The turbocharger fastening structure of claim 5,
wherein the at least one stopper includes hemming portions on first and second end portions thereof corresponding to first and second end portions of at least a gasket on which the at least one stopper is located, among the plurality of gaskets.
