초록

An internal comustion engine has an air induction system that provides an intake passage and an intake silencer, wherein there are a plurality of openings between the silencer and the intake passage. The openings can be selectively closed so as to effectively lengthen or shorten the flow path through the intake passage. upstream portions of the intake passage are disposed within the intake silencer so as to facilitate compactness of the induction system. The openings are closed during low and medium engine speeds, and are opened during high engine speeds...
