A configuration in which this control valve is opened and closed is known. With such a configuration, engine performance can be improved. However,
In order to optimally utilize such dynamic effects, it is preferable to shorten the length of the pipe upstream of the air cleaner, but if the length of the pipe upstream of the air cleaner is shortened, intake noise will occur.
