Description
Technical field
This utility model relates to the dividing plate of a kind of gas extraction system for motor vehicles and has this dividing plate
Acoustic filter.
Background technology
Exhaust noise is one of main source of motor vehicles noise, and reducing exhaust noise is to reduce car
The main path of noise.When the electromotor (gasoline engine or diesel engine) of motor vehicles works, meeting
Due to present in gas extraction system exhaustor, acoustic filter, exhaust gas filter etc. and produce certain back pressure,
This back pressure generally changes with the rotation speed change of electromotor.Back pressure is for the noise of vehicle, electromotor
The aspect such as power and moment of torsion has a direct impact, on the one hand, during engine speed height, and back pressure is relatively big, row
The noise produced in gas system is less, i.e. acoustic efficiency is fine, but owing to back pressure itself can consume necessarily
Power, so the power of electromotor and moment of torsion can be affected, and and then affect fuel efficiency；Separately
On the one hand, when engine speed is low, back pressure is less, situation is contrary, making an uproar of the generation in gas extraction system
Sound is very big, i.e. acoustic efficiency is poor, but the power of electromotor and moment of torsion are impacted less, and fuel efficiency is high.
In common vehicle exhaust system, both the above situation is likely to occur.
Traditional gas extraction system control valve is mainly made up of flexible member and valve seat, valve gap etc., and it is hit by a bullet
Property element (such as spring) mainly has torsion spring type, compressed spring type etc..As requested, gas extraction system controls
Valve is required to be arranged at acoustic filter baffle plate sometimes.This type of valve is non-dismountable after installing, valve gap area
With spring once it is determined that after, when to muffler tuning, regulation degree of freedom less, the most all pass through
Changing valve port area or change the realization of different-stiffness spring, this can affect acoustic filter development efficiency and cost
Higher.
