Claims

[Scope of utility model registration request]

In a V-type 8-cylinder internal combustion engine with a 90° crank arrangement and a supercharger, there is a pipe between the blower outlet side of the supercharger and the intake manifold pipe as viewed from the left of the internal combustion engine, from the blower outlet of the supercharger. An air supply pipe device for an 8-cylinder internal combustion engine, characterized in that an air supply connecting pipe is provided which can branch the air supply to the left and right air supply manifold pipes in a direction substantially perpendicular to each other.
