内燃機関の吸気装置。 One combustion chamber has two main and auxiliary intake passages, and the auxiliary intake passage is provided with an on-off valve that is opened and closed by a drive means driven by negative pressure introduced through the suction negative pressure passage. In the intake system for an internal combustion engine, the intake system includes a negative pressure storage tank disposed upstream of the drive means, and a cutoff valve disposed upstream of the negative pressure storage tank for opening and closing the suction negative pressure passage. An intake system for an internal combustion engine, comprising: a control means for detecting the operating state of the engine and closing the cutoff valve at least during operation in which the intake negative pressure becomes excessive.
