を特徴とする内燃機関の吸気装置。 Two intake ports are formed independently for each cylinder, and two intake ports are installed in each of these intake ports.
In an intake system for an internal combustion engine, the intake system includes two intake valves and a control valve that is disposed in one of the intake ports and opens and closes depending on engine operating conditions, when the control valve is fully closed, the bottom of the intake port of the valve body portion of the control valve is closed. The control valve is arranged so that the wall side is at the lowest position in the valve body part, and the communication passage communicates the intake port bottom wall part upstream of the valve body part and the other intake port when the control valve is fully closed. and a fuel injection valve that distributes and supplies fuel to the two intake ports upstream of the control valve.
