ABSTRACT:
Disclosed is a intake air control device for an internal combustion engine, which includes a swirl producing valve provided in the low speed intake tube for partly closing the intake port of the combustion chamber so as to impart swirling motion to the air flowing into the combustion chamber when operating the engine at a low speed including idling, an intake control valve provided in the high speed tube for completely closing the passage of the high speed tube when operating the engine at a low speed including idling. A valve control connects the accelerator pedal with the swirl producing valve and the intake control valve for simultaneously controlling the valves by moving the accelerator pedal so as to close the valves at a low speed including idling or to open the valves at a medium and a high speed, wherein the swirl producing valve is closed to make a narrow opening between its edge and the wall of the low speed intake tube for imparting the swirling motion to the intake air supplied from the surge tank to the combustion chamber.
