Claims

[Scope of utility model registration request]

A main path through which intake air flows from the opening of the intake manifold into the intake manifold, and a sub-path provided with a means for controlling the amount of intake air from the opening are formed in the main path, and the main path has a main path that allows intake air to flow into the intake manifold from the opening of the intake manifold. The intake port side main passages that supply intake air in a predetermined inflow direction are communicated with each other, and each of the intake port side passages formed in parallel with each of the intake port side main passages are communicated with the sub passages. An intake system for an internal combustion engine, in which, in addition to the intake air from the main passage, intake air from the secondary passage can also be supplied to the mouth by operating the intake air amount control means.
