Abstract
A suction apparatus for an engine is provided with an intake path which has an opening portion at one end, and the other end of which is connected to an intake pulsation generation source. A resonator is connected to a downstream portion of said intake path through a connecting pipe, for eliminating a (0.5+n)th-order (where n is an integer equal to or larger than 0) resonant wave in the intake path which is induced by a compression wave generated from said intake pulsation generation source toward the upstream side.
