複式吸気装置。A main intake system that supplies intake air to the combustion chamber under a predetermined load, and a sub-intake system that simultaneously supplies intake air to the main intake system under a load higher than the predetermined load, are installed at locations immediately upstream of the intake valve in the same combustion chamber. The auxiliary intake system communicates the intake ports or intake passages of two adjacent cylinders in a siamise shape, and the sub-intake system is partitioned to divide the inside into two parts at the gathering part of the siamise-shaped intake ports or intake passages. A wall is provided, and a check valve is installed at the end of the partition wall so as to open and close without interfering with the wall, and when the main intake system takes air, the check valve prevents adjacent cylinders of the sub intake system and other A dual intake system for an internal combustion engine characterized by simultaneously shutting off cylinders.
