Claims

[Scope of utility model registration request]

A fixed intake pipe that connects to the carburetor of a multi-cylinder internal combustion engine and a plurality of rotating arms connected to a rotating shaft rotated by a servo motor allow it to be moved toward and away from the fixed intake pipe. It consists of a slide valve and a guide pipe that slidably supports the slide valve, and when the rotational speed of the internal combustion engine is lower than a predetermined value, the slide valve is connected to the fixed intake pipe and the guide pipe supports the slide valve to a predetermined value. In the intake device having a variable length intake pipe configured to separate when the height is higher than A multi-cylinder type, characterized in that it is configured to be biased in one direction by an elastic member and rotated in the opposite direction by engagement with a stopper attached to the rotation shaft. Intake system for internal combustion engines.
