を特徴とするエンジンの吸気装置。 A long independent intake passage that is curved by an upstream portion consisting of a surge tank and an independent intake passage that branches off from the surge tank and extends in a downwardly curved manner, and a downstream portion that communicates with the intake port of each cylinder via the lower part of the upstream portion. An intake manifold constituting an intake expansion chamber is formed upstream of each of the independent intake passages, a plate is interposed inside the curved part between the upstream part and the downstream part of the intake manifold, and A communication section that branches off from the middle of the passage and communicates the independent intake passages with each other, and a control means that controls the communication between the independent intake passages through the communication section according to the operating state of the engine, the communication section A part of the wall defining the plate is formed of the plate, and a negative pressure chamber serving as a driving source for the control means is formed on the side opposite to the communication portion of the plate. .
