Claims

[Scope of utility model registration request]

It consists of a chamber extending in the direction of the cylinder row in the internal combustion engine, and a plurality of branch intake pipes that independently connect the chamber and the intake port of each cylinder in the internal combustion engine for each cylinder, and each of the branch intake pipes In an inertia supercharging intake manifold configured such that the interval between the pipes is narrower on the side connected to the chamber than on the side connected to the internal combustion engine, the interval between each branch intake pipe among the branch intake pipes; In an internal combustion engine, the cross-sectional area of a branch intake pipe whose pipe length is shortened by narrowing the pipe length on the side connected to the chamber is made larger than the cross-sectional area of another branch intake pipe whose pipe length is longer. Inertia supercharging intake manifold.
