いて、独立の吸気管をスロツトルバルブ下流にて
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
配管にて接続し、該配管に、スロツトルバルブに
連動しスロツトルバルブがアイドル開度付近で導
通を遮断しスロツトルバルブがアイドル開度より
大の所定の開度で導通状態となるバルブ機構を設
けたことを特徴とする連通管の制御機構。 In a multi-cylinder internal combustion engine with an independent intake system, the independent intake pipes are connected through the same communication pipe downstream of the throttle valve, and the communication pipe is connected to a charcoal canister that temporarily adsorbs fuel evaporative gas. A valve mechanism is provided in the piping, which interlocks with the throttle valve so that the throttle valve shuts off conduction near the idle opening, and the throttle valve becomes conductive at a predetermined opening greater than the idle opening. A communication pipe control mechanism characterized by:
