吸気装置。 The intake passage leading to the combustion chamber is separated by a separation wall, one side is a straight port, and the other is a helical port.A flow control valve is provided on the straight port, and both intakes are passed through a communication hole formed in the separation wall downstream of the flow control valve. In an intake system for an internal combustion engine equipped with a fuel injection valve that supplies fuel to a port, a gap is provided on the separation partition side of the flow control valve, so that even when the flow control valve is closed, some intake air passes through the gap and enters the separation partition. In addition, a protrusion protruding toward the straight port is formed on the separation wall defining the downstream end of the communication hole, so that some of the flow along the separation wall when the flow control valve is closed is controlled. An intake device for an internal combustion engine, characterized in that intake air is guided by the protrusion and flows through a communication hole toward a helical port.
