Document Type and Number:
Japanese Patent JP7003681
Kind Code:
B2
Abstract:
To improve a flow of intake air which is introduced into a cylinder from an intake port.SOLUTION: An intake manifold of an internal combustion engine comprising a first intake port 11 and a second intake port 12 each introducing intake air into a cylinder C comprises a first intake pipe conduit 30 connected to the first intake port 11, and introducing intake air into the first intake port 11, and a second intake pipe conduit 40 connected to the second intake port 12, and introducing intake air into the second intake port 12. An opening diameter of at least an outlet part of the first intake pipe conduit 30 is formed smaller than an opening diameter of at least an inlet part of the first intake port 11, and a difference-in-level portion 67 is formed in a connecting region between the first intake pipe conduit 30 and the first intake port 11.SELECTED DRAWING: Figure 6
