<p><P>PROBLEM TO BE SOLVED: To provide an intake passage structure of an internal combustion engine capable of further suitably varying the flow, flow rate and the flowing direction of intake air. <P>SOLUTION: An intake passage is formed as a double structure of an outside intake passage A and an inside intake passage B in the intake passage, and has a movable pipe 1 having an abutting part abutting on an upstream side end part of an intake manifold 11 in the upstream side end part and opening and closing the intake passage A by the abutting part. The movable pipe 1 extends up to the vicinity of an intake valve 56 possessed by the internal combustion engine 50, and does not contact with the intake manifold 11 except for the abutting part. The upstream side end part of the intake manifold 11 projects in a surge tank 12. The abutting part of the movable pipe 1 and the upstream side end part of the intake manifold 11 mutually abut in the surge tank 12. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
