Claims

[Scope of utility model registration request]

A rotary valve is interposed in the natural intake passage that supplies natural intake air to the combustion chamber of the engine, and the rotor of the rotary valve is penetrated in the radial direction to communicate with the natural intake passage at a predetermined timing, thereby supplying natural intake air to the combustion chamber. A main passage capable of supplying intake air, and a sub passage whose one end opens at a position offset in the axial direction of the rotor with respect to the open end of the main passage and whose other end communicates with an intermediate portion of the main passage. , an internal combustion engine with a supercharger, characterized in that one end of the auxiliary passage is provided so as to be able to supply supercharged intake air to the combustion chamber by communicating at a predetermined timing with a supercharged intake passage in which a supercharger is interposed. Engine intake system.
