An intake combustion resonator including an enclosure which includes a resonator
tube assembly passing through the enclosure. The resonator tube is formed from
porous, undulated tube material and has openings formed in the tube walls. The
openings serve as "tuned" passages through the porous tube walls. The resonator
tube assembly is not centrally located within the enclosure but rather it is offset
both in a height and a width orientation. The size, spacing, and orientation of
the tube openings, porous, undulated sleeve material, the design of the enclosure,
and the placement of the tube within the enclosure, all act in concert to give
rise to the noise abatement properties of the present invention.
