特徴とする多気筒内燃機関の吸気装置。 An intake passage provided with a throttle valve is connected to a surge tank, and branch pipes extending from the surge tank are communicated with the combustion chambers of each cylinder of a multi-cylinder internal combustion engine, so that cylinder groups of the engine are connected to the first cylinder group and the second cylinder group. A multi-cylinder internal combustion engine is divided into cylinder groups, and the inside of the surge tank can be divided by a control valve into a first space communicating with the first cylinder group and a second space communicating with the second cylinder group. In the intake system, a bypass valve is provided which connects the intake passage upstream of the throttle valve and the first space of the surge tank through a bypass passage, and opens and closes the bypass passage, and the control valve is connected at least when the engine is started. An intake system for a multi-cylinder internal combustion engine, characterized in that it is configured to be opened.
