。[Scope of Claim for Utility Model Registration] For each intake pipe of each cylinder, a cutoff valve, a sub-intake pipe that communicates between the upstream side and the downstream side of the cut-off valve of each intake pipe, and opening/closing of the sub-intake pipe, respectively. In an intake system for an internal combustion engine equipped with a control valve, the engine load detecting means and the control valve of each intake pipe are operated when the engine load is from idling to a predetermined value.
The control valve is opened only during the period when the intake valve is closed, and the valve opening period is extended as the engine load increases, and when the engine load exceeds the predetermined value, the control valve is opened as the engine load increases. An intake system for an internal combustion engine, characterized in that it is provided with a control means for delaying.
