ABSTRACT:
A resonator is arranged in an intake system including a pipe section for partitioning an intake port from an intake passage that communicates the intake port with a combustion chamber of an engine, the resonator including: a branch pipe having one end branching to the pipe section and the other end closed so that a silencing chamber is defined therein; and at least one partition wall for partitioning the silencing chamber into at least one pneumatic spring chamber, the partition wall having a natural frequency lower than the frequency of silencing target sound of intake noise propagated from the intake passage.
