Description
Technical field
The technical field of automobile engine is the utility model is related to, is especially adapted for use in all carrying exhaust gas turbocharge hairs
The vehicle of motivation.
Background technology
With the development of automobile items technology, automobile function is also more and more, and the hardware device for needing to arrange also increases therewith
More, most equipment needs to be arranged in enging cabin, which results in car engine room space is more and more narrower and small, and for ensureing
The headspace of the component such as gas handling system silencer of vehicle NVH performances is inevitably compressed, and causes vehicle intake
System noise cannot meet the desired value that vehicle development is fixed early period.
The common noise frequency of exhaust gas turbocharge engine aspirating system generally between 1000-3000Hz, compared to
For naturally aspirated engine intake system noise, frequency is higher, wider range, for it is such the problem of, it is necessary to wideband eliminate the noise
Device, usually sets 4-6 high-frequency resonant cavity, volume is in 0.5-1.5L or so, but the space of enging cabin is less and less, it is impossible to
Meet the space that silencer is reserved, cause inlet noise big, vehicle NVH poor performances.
The content of the invention
Present invention is generally directed to the high-frequency noises that air inlet system of supercharger engine is common, there is provided a kind of new automobile disappears
Sound device, this novel automobile muffler are integrated with decorative cover of engine and silencer, are arranged in above engine, solve booster
The problem of silencer arrangement space is insufficient, acoustical absorptivity is poor.
The present invention, which provides a kind of new automotive muffler structure, mainly to be included：Engine decorative over body case, engine dress
Adorn over body case fixing bracket, air inlet pipeline, resonator I, resonator II, resonator III, resonator IV, heat insulating mattress fixing bolt
Hole.
Heat insulating mattress is arranged between decoration over body case, heat insulating mattress is fastened by bolts at further engine cylinder cover
In the heat insulating mattress fixed bolt hole of Decorative Cover lower housing portion, heat caused by engine operation is separated.
Further engine decorative over body case is fastened by bolts by engine decorative over body case fixing bracket to be started
On machine body.
Further air inlet pipeline stage casing design resonator I, resonator II, resonator III, resonator IV, eliminate engine
The some specific frequency noises of gas handling system.
Further engine decorative over body case and air inlet pipeline integrated molding, air inlet pipeline, resonator and engine
Decoration over body case collectively forms this structure.
Trade mark fixed position at further decorative cover of engine housing upper surface design one, can be clamped specific business herein
Mark.
The present invention possesses the medium, high frequency noise immune for eliminating exhaust gas turbocharge engine aspirating system, while also has
The effect of decorative cover of engine, saves engine nacelle space, and beautiful；
Its of the invention inner space is made of Decorative Cover housing upper surface and the space that lower surface surrounds jointly, centre by every
Plate is separated into several chambers, and the arrangement of these partition plates, strengthens the rigidity of upper surface, avoid Decorative Cover upper table surface radiation from making an uproar
Sound.

Fig. 3 is the profile of the utility model
In figure（1）For engine decorative over body case fixing bracket；（2）For air inlet pipeline；（3）For brand trademark reserved place
Put；（4）For heat insulating mattress fixed bolt hole；（5）For resonator I；（6）For resonator II；（7）For resonator III；（8）For resonator
Ⅳ；（9）For engine decorative over body case.
Embodiment
What deserves to be explained is all way of example are for illustrating a kind of structure of new automotive muffler below
Composition and advantage, but all descriptions are intended merely to what is described the problem, and should not be considered as limitation of the present invention.Under
The direction words such as " on ", " under " that is mentioned in the content of face, "left", "right", "front", "rear" are intended merely to what is described the problem, also should
This is considered as the limitation of the present invention.
With decorating over body case at engine cylinder cover（9）Between arrange heat insulating mattress, heat insulating mattress is fastened by bolts and is being decorated
Over body case（9）The heat insulating mattress fixed bolt hole of lower part（4）In, separate heat caused by engine operation, decorative cover of engine
Housing（9）By engine decorative over body case fixing bracket（1）It is fastened by bolts on engine body.By sky in gas handling system
The cleaned air that air cleaner comes passes through air inlet pipeline（2）The mouth of pipe enters, and by this silencer, and then enters turbocharger
Compressor, due to the sound that turbocharger operation produces, along opposite path, is passed through, into air inlet pipeline by compressor（2）
In, respectively by the noise elimination of resonator IV 8, resonator III 7, resonator II 6, resonator I 5, into air cleaner, final warp
Air inlet is crossed to travel to outside car.
Claims (3)
