Claims

[Scope of utility model registration request]

Two intake ports are provided for each cylinder, an intake air control valve is provided in one of the two intake ports, and the intake air control valve is disposed in the center of the intake manifold. The intake air control valve is opened and closed via an intake air control valve shaft that extends from the center toward the intake ports at both ends and passes through intake spokes other than the intake ports at both ends;
Intake port 1 where the intake air control valve shaft passes through the intake pipe length of the intake port where the intake air control valve shaft does not pass through.
The structure of the intake manifold is characterized by being longer than the intake pipe length.
