Point.
As shown in Figure 1 to Figure 3, in the present embodiment, the pressure relief of the exhaust apparatus, comprising: silencer 100, silencer
100 include inlet end 102 and the outlet side 104 opposite with inlet end 102, is equipped in silencer 100 and is arranged close to inlet end 102
The first expansion chamber 110；And the exhaust pipe 200 being connected to the exhaust outlet of engine, exhaust pipe 200 include the first tube body 210, the
One tube body 210 is set in the first expansion chamber 110, and the installing port of the outer wall and inlet end 102 of one end of the first tube body 210 is close
The side wall of envelope connection, the first tube body 210 is equipped at least two relief holes, and all relief holes are along same circumference nonuniform mutation operator.
Such as Fig. 4 to Fig. 5 analysis it is found that the relief hole of the pressure relief of above-mentioned exhaust pipe 200 is in the circumference side of exhaust pipe 200
Asymmetric arrangement is presented upwards, gas enters the first expansion chamber 110 by relief hole in exhaust pipe 200, at this moment the work of relief hole
With being not only the effect for discharging pressure at expulsion, the effect of exhaust resonance is also acted, is equivalent to and is devised on exhaust pipe 200
At least two resonance models (the corresponding resonance model of a relief hole).The when of compression when such first intracavity gas pressure
And expand, such as same gas spring acts on gas in exhaust pipe 200 by relief hole, to change the arteries and veins of pressure at expulsion
It is dynamic.Asymmetric arrangement is presented in the relief hole on the circumferencial direction of exhaust pipe 200, therefore resonance effect will not phase between relief hole
It mutually offsets, and then exhaust gas pulses effect can be made full use of to improve engine volumetric efficiency.In addition, it is main to influence exhaust wave reflection
Parameter is the first tube body 210 and the first expansion chamber 110, and relief hole (such as the first relief hole 212, the second relief hole 214) is opened in
First expansion chamber 110, can be avoided gas and short circuit phenomenon occurs, further increase the performance of exhaust apparatus.

In cone.Relief hole is set on the cone of the first tube body 210, the sectional area of the cone closes up from big to small, pressure
It increased dramatically, gas pressure change on the conical surface is larger, especially the exhaust of high temperature and pressure, and pressure release effect is best herein, because
It can reduce behind taper that longer diameter is compared with small tubes flow velocity in this way, to reduce resistance；It simultaneously can be to avoid high-speed flow pair
Surrounding cylinder wall surface direct collision reduces resistance gas fluid resistance loss.
It should be noted that " all relief holes are along same circumference nonuniform mutation operator " refers to the face of at least one relief hole
The size and/or all relief holes of product size and other relief holes are in asymmetric arrangement.
In addition, at least two relief holes are arranged at intervals at same side.
On the basis of the above embodiments, in an embodiment, as shown in Figures 4 and 5, relief hole includes being arranged at intervals at together
At least two at least two first relief holes 212 of one side and the side being arranged at intervals at except the first relief hole 212
A second relief hole 214；Wherein, on the same circumference, angle is A1 between the center line of two neighboring first relief hole 212,
Angle is A2 between the center line of two neighboring second relief hole 214；Wherein A1 < A2.
Further, in an embodiment, the area of all first relief holes 212 is D1, all second relief holes 214
Area is D2；Wherein, D1 > D2.In this way, the shape of first relief hole 212 and the second relief hole 214 can be according to reality
It is selected.When first relief hole 212 and the second relief hole 214 are circular hole, aperture can use to be counted
It calculates.
Specifically, the quantity of the first relief hole 212 and the second relief hole 214 is three, and D1=10mm, D2=6mm,
A1=50 °, A1=90 °, the angle between the center line of the first adjacent relief hole 212 and the center line of the second relief hole 214
It is 40 °.
