Strictly, the main operation of the secondary air control system is to inhale the outside air through the control intake manifold and to burn it in the second place, so as to reduce the pollution generation. The control valve intake pipe is connected to the boundary air two air "ιΙΓ = body suction a large amount of the outside of the road for the second job. Line, then into the Μ 汽 汽 汽 然而 然而 然而 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 二次 二次 二次 二次 二次 二次The action will produce inhalation noise, which is not very ^^' because of suction 20 [Summary] The present invention is a locomotive of a secondary air intake pipe, and the locomotive mainly includes a muffler structure locomotive frame And FAW 5 8 1259863 The above locomotive frame comprises a hollow tubular frame body, and the frame body comprises a closed end and an open end, and the frame body is internally formed with a hollow Channel. Bu's cylinder package 3 has a secondary air system, and this secondary air system: charging,:-control valve, and a control valve intake pipe, wherein one end of the control valve intake pipe is connected to control The other one of the intake valves of the control valve is a hollow passage that communicates with the body of the frame. The feature is that the above-mentioned frame body includes a muffler 10 5 and the mouthpiece is column-shaped and plugged in Inside the open end of the frame body of the frame, /曰兀亚开 has a - intake port, which is the channel and the outside of the frame body. Pingmu Lu Yuedan's second is so - come, when the secondary air system is activated, it can be used The pipe body is sucked into the external 4 valve into the milk officer, and can be used in the car by the sound absorbing component: 2, when the process of inhaling the outside air is several times in the dry wood official body, the secondary air system is activated. The generated noise noise can be made of plastic - the outer ring wall and the inner ring wall 4 can include a p-crystal-specific distance, and the outer ring wall plugs I = the outer ring walls are mutually In the mouth end, the inner ring wall surrounds the tube: the valley sighs and extends on the opening channel of the frame body. The outer ring is facing the hollow top to abut the piece, so as to insert the piece of material and at least two Forming a fixed, of course, the outer circumference of the outer ring wall of the open end of the top R soap wood body. The sheet can also be non-equal angle The sound-dissipating component provided in the 1,259,863 may include a sound-absorbing structure, the body of the system is made of ==:r:r, and the sound absorbing cotton is used. The aforementioned ribs are different between the inner and the inner, and the sound-absorbing cotton may be a cylinder. The frame cylinder of the frame can be assembled in the locomotive by at least the screw-locking method. [Part 10: When: Figure 1 is a perspective view of the locomotive of the present invention - a preferred embodiment - Figure 2 The present invention - a preferred embodiment - an engine surface view and FIG. 3 is a partial view of a second embodiment of the present invention - a preferred (four) embodiment, showing a locomotive 5, and the locomotive 5 includes a locomotive - and - Condition cylinder 2. Among them, the locomotive frame α contains a frame body 11 of the frame body, and the frame body of the frame body 1 is 5 ln, and <η邛 is formed with a hollow channel 3'^the frame body (10) The ends are respectively formed with a closed end (1), - at the same time, the frame body nnU2 is internally plugged with - silenced in the embodiment, the above-mentioned muffler (4) 3 series, made of plastic, and 21" piece 3 contains an intake air The port 31, the outer ring wall 32, the three top abutting pieces 32, the inner ring wall 33, and a sound absorbing center. The towel, the air inlet 3 i provided by the sound absorbing member 3 can communicate with the hollow passage] i 3 and the outer tube of the rudder tube (4) and the outer ring wall 32 and the inner ring wall 33 are spaced apart from each other - specific (four) heart _ outside « 32 outer circumference 4 angle convex is provided with the above three top cymbals. 1259863 In addition, the inner ring wall 33 of the sound absorbing member 3 is circumferentially tubular and extends from the air inlet 31 of the sound absorbing member 3 axially toward the body of the frame body 〜1. The sound absorbing structure 34 includes a plurality of ribs 341 which are six-folded with each other, and the sound absorbing structure 34 is accommodated within a specific distance d of the outer ring wall 32 and the inner ring wall. In addition, the above-mentioned cylinder 2 is assembled on the frame body u of the locomotive frame, and the cylinder 2 can be locked to the frame body 11 by screws (not shown). The cylinder 2 includes a second time. An air system 21, the secondary air system further includes a control valve 211 and a control valve intake pipe 212, and one end of the control valve intake pipe 102 is connected to the control valve 211 'control valve intake pipe 212 The other end of the L is connected to the hollow passage 113 of the frame body 11. Therefore, when the secondary air system 21 is actuated, its control valve intake pipe 212 can draw in outside air via the frame tube body 11, and in the process of drawing in the outside air, the muffling member 3 can be used in the frame body u. The noise reduction space 15 formed in the interior effectively reduces the sound absorption generated by the secondary air system 21 when it is actuated. Please refer to FIG. 4 for a partial cross-sectional view of another preferred embodiment of the present invention. The main structure of the present embodiment is substantially the same as that of the above embodiment, except that the rib 341 (please (4) FIG. 3) is changed to sound absorbing. Cotton 342, and such a design can also achieve the purpose of silence, and the same effect as the above embodiment can be achieved. The above embodiments are merely illustrative for the convenience of the description, and the scope of the claims is intended to be limited by the scope of the claims. 8 1259863 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic structural view of a portion of a locomotive according to a preferred embodiment of the present invention. 2 is a schematic view showing the appearance of an engine according to a preferred embodiment of the present invention.
