Air admission hole 911, taper hole 9112, straight hole 91121, discharge chamber 912 and tail chamber 62 can be sequentially passed through and enter rear chamber 80, the bottom of due to
The first spoiler 92 is equipped in slot 9132, rake 922 can generate inhibition to air-flow, make the flows decrease of air-flow, noise
Reduce；Again since the major diameter of taper hole 9112 is less than the aperture of air admission hole 911, thus blocking again can be carried out to air-flow, and
And sound wave can also collect, and so that some sound waves is interfered, cancel out each other, reduce noise；In addition to this, due to taper hole 9112
Aperture is gradually reduced, thus generates inhibition to air-flow always so that flows decrease, noise reduce；Again because in straight hole
The second spoiler 93 is equipped at 91121 gas outlet, thus air-flow can be by the barrier effect of the second spoiler 93, in air-flow
The lower hook part 934 of effect is it also occur that the changing of the relative positions, and under the inhibition of the second spoiler 93, the flows decrease of air-flow, flow direction is sent out
Raw to change, the noise that tail gas generates reduces again, and being located at gas in rear chamber 80 can be by the air inlet of escape pipe 30 and the
Then two ventholes 31, which enter in escape pipe 30, drains into the external world.
The present embodiment provides a kind of motorcycles, including above-mentioned muffler.
It these are only the preferred embodiment of the present invention, be not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.Any modification made by all within the spirits and principles of the present invention,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
