しめた内燃機関の吸気制御装置。 Each cylinder is equipped with a pair of intake valves, one intake passage for each cylinder is branched into two intake ports, and each intake port is connected to the same combustion chamber through the corresponding intake valve. A partition wall is formed inside each intake port that hangs downward from the upper wall surface of the intake port, extends in the longitudinal direction of the intake port, and terminates near the intake valve. In an internal combustion engine that is separated into an outer intake port portion that opens into the combustion chamber near the circumferential surface and an inner intake port portion that opens into the combustion chamber near the cylinder axis, a control valve is provided at each inlet portion of the outer intake port portion. An intake control device for an internal combustion engine, which opens the control valve when the engine is under high load or at high rotational speed.
