いて、各吸気管のスロツトルバルブ下流にポート
を設けて各ポートを同一の連通管により連通し、
該連通管を燃料蒸発ガスを一時吸着しておくチヤ
コールキヤニスタに配管により接続し、前記連通
管内には連通管内で回動可能でかつ前記ポートに
対向する位置にスリツトを設けた円管を挿入し、
該円管をスロツトルがアイドル開度付近ではポー
トとスリツトとの導通は無いガスロツトルがアイ
ドル開度以上で所定以上に開くとポートとスリツ
トとの導通があるようにスロツトルバルブに連動
させたことを特徴とする連通管の制御機構。 In a multi-cylinder internal combustion engine having an independent intake system, a port is provided downstream of the throttle valve in each intake pipe, and each port is connected through the same communication pipe,
The communication pipe is connected by piping to a charcoal canister that temporarily adsorbs fuel evaporative gas, and within the communication pipe is a circular pipe that is rotatable within the communication pipe and has a slit at a position facing the port. Insert
The circular pipe is linked to a throttle valve so that there is no electrical connection between the port and the slit when the throttle is near the idle opening, but there is electrical continuity between the port and the slit when the gas throttle opens beyond a predetermined amount at or above the idle opening. Characteristic communication pipe control mechanism.
