Claims

[Scope of utility model registration request]

In an intake system for a multi-cylinder internal combustion engine, a volume part is provided where the intake passages of each cylinder gather, and openings of the intake passages gathered in the volume part are arranged at equal intervals on a circumference according to the ignition order, and at least A disc-shaped poppet valve having a hole or notch that closes one opening and opens the other opening is arranged so as to be in contact with the opening surface of the opening, and the poppet valve is rotated in synchronization with the rotation of the internal combustion engine. thereby sequentially closing the openings, and moving the poppet valve or the opening surface in the axial direction between a contact position where the poppet valve contacts the opening surface and a non-contact position where the poppet valve contacts the opening surface. An intake amplitude control device for a multi-cylinder internal combustion engine.
