Abstract
A Helmholtz resonator communicates with an interior of an intake passage, which is configured to draw intake air to a combustion chamber of an engine. The Helmholtz resonator has a volume chamber and a communication pipe. The volume chamber forms a resonance chamber. The communication pipe communicates the volume chamber with the intake passage. The communication pipe includes an acoustic stack, which is configured to cause a temperature gradient by utilizing an acoustic energy.
