To) it with plane C angulation α locating for the extension path of bending tube section 12 is 100 ° -110 °.
As shown in Fig. 2, one end with gas outlet 16 of air inlet output pipeline section 13 inputs the side of pipeline section 11 to separate air inlet
To deflection, so that one end with gas outlet 16 of air inlet output pipeline section 13 is with air inlet input pipeline section 11 with air inlet 15
One end between open space be greater than C-shaped bending tube section 12 both ends between open space.
In present embodiment, the cross-sectional area of pipeline main body 1 is preferably 0.003m2-0.012m2, the length of extension path is excellent
It is selected as 500-700mm, it is highly preferred that the extension path length is 600-700.The length of pipe enables to the air cleaner
Air inlet pipeline has preferable erasure effect, and is unlikely to impact intake resistance again.
What the pipeline main body 1 of structure as described above was mainly eliminated is low frequency noise, to make the air inlet pipeline have width
Frequency noise dampening efficiency is mainly used for as shown in Figure 1, being provided at least one 1/4 wavelength tube, 2,1/4 wavelength tube in pipeline main body 1
Eliminate high-frequency noise, in the present invention air-cleaner snorkel road be integrated with 1/4 wavelength tube 2 so that the filter into
While air pipe has low frequency acoustical absorptivity, high frequency noise can be also eliminated.
Preferably, the setting of 1/4 wavelength tube 2 is certainly not limited on air inlet output pipeline section 13, and there are two arrangements
Two, can be one or more.
In addition, being so that the air-cleaner snorkel road facilitates installation, it is preferable that bending tube section 12 and air inlet input pipe
The junction of the junction of section 11 and/or bending tube section 12 and air inlet output pipeline section 13 is provided with flexible buffer pipeline section 14, this is soft
Property buffering pipeline section 14 be preferably bellows, be certainly not limited to bellows, can also be hose.Since flexible buffer pipeline section 14 makes
The air-cleaner snorkel line state is unstable, and structure type and angle setting as described above etc. is the air inlet pipeline
Preferred structure state in application.
Air-cleaner snorkel road provided by the invention is verified through test simulation and practical application, is had preferable
Erasure effect.Its Simulation results is as shown in fig. 7, the curve a in figure is with air-cleaner snorkel provided by the invention
Road carries out what noise reduction emulated, and the air-cleaner snorkel road in the prior art curve b carries out noise reduction and emulates to obtain,
By comparing it will be evident that carrying out noise reduction with air-cleaner snorkel road provided by the invention, noise is substantially reduced, and
And the peak value of noise is mobile to the direction of low frequency compared to existing air inlet pipeline, that is, the intrinsic frequency of the air inlet pipeline is compared
The frequency of existing air inlet pipeline reduces, and is conducive to avoid the resonant frequency of engine in this way, in order to avoid generated more with engine resonance
Big noise.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
