Abstract
An intake manifold is provided and includes a runner that is connected between a plenum and a cylinder head to allow air introduced into the plenum to enter the cylinder head. A dent is formed at the runner such that the dent extends along a channel of the runner while having an inner surface with a protruding shape. The runner has, at an end thereof, an inner surface formed to be flat without being formed with the dent. The inner surface of the runner is connected to the cylinder head.
Claims15
An intake manifold, comprising:
- a runner connected between a plenum and a cylinder head, wherein air is introduced into the plenum to enter the cylinder head;
- and
- a dent formed at the runner, wherein the dent extends along a channel of the runner while having an inner surface with a protruding shape,
- wherein the runner includes at a first end thereof, an inner surface formed to be flat without being formed with the dent, and the inner surface of the runner is connected to the cylinder head,
- wherein the runner includes:
- a first section formed to have a tubular structure with a curved shape having a predetermined curvature, and connected to an outlet of the plenum at a first end thereof, and
- a second section formed to have a linear tubular shape, and joined to a second end of the first section at a first end thereof while being connected to a port of the cylinder head at a second end thereof, and
- wherein the dent includes:
- a uniformly-shaped dent portion formed along an inner surface of the first section to have a uniform cross-section with a predetermined shape, and
- a variably-shaped dent portion formed along an inner surface of the second section, and connected to the uniformly-shaped dent portion.
