の吸気装置。 A V-type multi-cylinder engine that has an intake manifold with a collecting part in the center and branches extending in all directions from the collecting part, and the collecting part has a cylindrical shape with a groove on the bottom. It is set low in the center of the V-shaped valley, and each branch is slanted upward to connect to the intake port of each cylinder,
The downstream end of the bypass led out from the lowest part of the groove is connected to the immediate upstream side of the intake valve of each cylinder intake port, and a ring-shaped swirling chamber with an intake passage introduced horizontally in the tangential direction is stacked on top of the gathering part. A cylindrical slit formed in the lower part of the periphery of the rotating chamber communicates with the gathering part, and the opening degree of the slit is made variable by a piston valve that is slid on the periphery of the rotating chamber and is biased upward. Intake system for a V-type multi-cylinder engine.
