Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer in Fig. 1 and Fig. 2, the utility model embodiment, a kind of automobile exhaust pipe tuning silencer, including muffler
Main body 1, the right-hand member of muffler body 1 connects once isocon 5, automobile high pressure exhaust gas is shunted, an isocon 5
Right-hand member, which is connected with the inside of tail gas inlet pipe 6, the right-hand member of muffler body 1, is provided with rotary shaft 4, and the middle part of rotary shaft 4 is connected with rotation
Block 8, the outside of spill spin block 8 is uniformly provided with pivoting leaf 7, and pivoting leaf 7 is shaped as spiral shape, so as to add pivoting leaf 7 and high pressure tail
Provided with three pieces of dividing plates 17 inside the contact area of gas so that pivoting leaf 7 sufficiently rotates, the muffler body 1, described in middle part
Echo chamber 2 is provided between dividing plate 17 and the right side dividing plate 17, for the temporary transient importing of air-flow, the right side left end of dividing plate 17 connects
Second diffluence pipe 3 is connected to, the left end of second diffluence pipe 3 connects once hush pipe 9, and the middle part upper end of dividing plate 17 is connected with secondary
Hush pipe 16, secondary hush pipe 16, a left end of hush pipe 9 and No. three right-hand members of hush pipe 10 are equipped with noise reduction air admission hole, middle part
