Claims

[Scope of utility model registration request]

A plurality of cylinder groups are formed by combining cylinders whose intake strokes are not continuous, and a communication passage is provided to communicate the volume parts provided independently for each cylinder group, and a communication passage is provided on the side in the flow direction of intake air within this communication passage. A casing having openings at positions substantially opposite to each other is provided in the communication passage, and a valve body for opening and closing the communication passage is rotatable within the casing by a driving means that operates according to the operating state of the engine. An intake path control device for an internal combustion engine, characterized in that:
