。 Each intake pipe of each cylinder is provided with a shutoff valve and a control valve that controls the air filling amount downstream of the shutoff valve, and at least when the engine is under low load, each intake pipe is closed by the shutoff valve, and the intake pipe of each cylinder is The control valve is closed during the valve closing period, and the control valve is opened for a predetermined period of time during the intake valve closing period of each cylinder to fill the intake port downstream of the shutoff valve with a predetermined amount of air. In an intake air amount control device for an internal combustion engine, valve opening control opens a control valve of an intake pipe of each cylinder for a time proportional to a fuel injection time in conjunction with fuel injection from a fuel injection valve of each cylinder. 1. An intake air amount control device for an internal combustion engine, characterized by comprising means.
