気装置。[Scope of Claim for Utility Model Registration] A shutoff valve that shuts off the intake port of each cylinder during idling is placed close to the upstream side of the fuel injection valve located near the intake valve, and the intake passage upstream of the throttle valve and the intake passage downstream of the shutoff valve are arranged close to each other. In an intake system for an internal combustion engine, the control valve is connected to an intake port by a bypass path, and a control valve that opens during the intake valve closing period and supplies fresh air to the intake port downstream of the cutoff valve is interposed in the bypass path, A volume variable means for varying the intake port volume downstream of the shutoff valve in accordance with engine operating conditions is provided downstream of the shutoff valve, thereby making it possible to vary the amount of intake air to the engine during idling. Intake device.
