Description
Technical field
This utility model relates to automobile exhaust pipe correlative technology field, refers in particular to the screw mandrel group of a kind of car tail larynx
Part.
Background technology
Tail larynx is again car tail larynx, and it is mounted in the parts of original-pack aerofluxus tail end.The decoration aerofluxus of mobile muffler tail pipe
Pipe tail larynx, it, in addition to being prevented from automobile tail gas pipe deformation, simultaneously works as supercharging and flow-disturbing effect, it is also possible in certain journey
Make exhaustor sound become the softest pleasing to the ear on degree, reduce noise.But a lot of car owners buy reason and are also because it and have pole
Strong decoration function.
Tail larynx is different according to kind, and practical function has several: 1, have the tail larynx of special fire safety, on such as oil truck
And some is extraordinary with automobile-used；2, beauty function purely, has the tail larynx of a lot of chromium plating to be fixed on the aerofluxus of original irony
Mouthful, increase aesthetic property；3, motion repacking, this mainly increases aerofluxus sound, aerofluxus in this tail larynx by can produce as
The blare that sport car is general, but reality does not has any lifting to power, if in these tail larynx install appropriate all without
Affect aerofluxus；4, tail larynx is divided into band silencing net and without silencing net, and the major function of certain band silencing net is exactly certain disappearing
Sound is special！
Car tail larynx is arranged on automobile tail exhaustor, and existing car tail larynx is changeless, so garage
During sailing, when engine speed raises, capacity strengthens the most therewith, is now unfavorable for the discharge of waste gas；Work as automobile engine
When rotating speed is relatively low, capacity is less, can not change exhaust back pressure, causes the loss of moment of torsion.
