Embodiment
For technical problem, technological scheme and advantage that embodiment of the present utility model will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Embodiment of the present utility model is for directly drive gas port in prior art on air-strainer, can produce larger induction noise, reduce driver or occupant's travelling comfort, disturb even the problem of speech communication, a kind of air inlet leading pipe and air-strainer are provided, can effectively reduce induction noise.
The utility model provides a kind of air inlet leading pipe, is used for being arranged on the suction port place of air-strainer, and wherein, air inlet leading pipe is variable section structure.
Owing to being subject to the air-strainer size and arranging the restriction that can't change, the utility model embodiment only changes the setting at air-strainer suction port place, increase the air inlet leading pipe of a variable section structure at the suction port place of air-strainer, by noise testing, after adopting the technical solution of the utility model, more than the noise ratio of gas handling system originally reduced 1db, can reach thus the purpose that reduces induction noise, improve car load NVH(Noise, Vibration, Harshness, noise, vibration, sound vibration roughness) performance and occupant's travelling comfort.
Figure 1 shows that the structural representation of the utility model embodiment's air inlet leading pipe 1, as seen from Figure 1, the section area of air inlet leading pipe inlet end 2 and outlet air end 3 is all less than the section area in air inlet leading pipe stage casing.
Further, as shown in Figure 1, the cross section of the inlet end 2 of air inlet leading pipe can be flat mouthful of shape.
Further, the pipe thickness of air inlet leading pipe 1 of the present utility model is not less than 3mm.Wherein, the length that air inlet leading pipe 1 is positioned at air-strainer body 4 inside can be 50mm, and the length that is positioned at air-strainer body 4 outsides can be 200mm.
