。 機関の吸気通路構造。[Scope of Claim for Utility Model Registration] A reed valve type check valve is interposed in the vicinity of the intake valve in the intake passage communicating with the combustion chamber via the intake valve, and a substrate of the check valve is installed in the intake passage. The entire check valve is configured to be rotatable by being pivoted near the wall, and an intake passage is provided between the Joetsu check valve and the intake valve that is approximately perpendicular to the rotation direction of the check valve. The internal combustion engine is characterized in that a partition wall is provided to partition the interior into at least two layers, and the rotation angle of the check valve is changed according to the operating state of the engine.
. Engine intake passage structure.
