Then, the internal structure of baffler 18 described.Fig. 6 (A), (B) are the perspective elevation of expression after the part of baffler 18 removal muffler body 18A.In addition, in Fig. 6 (A), (B), also exist for convenient and not shown parts.And, in the following description, there is the situation that the side near apart from outlet pipe 23 sides in the exhaust passageway in the muffler body 18A described as the downstream as upstream, a side far away.
Shown in Fig. 6 (A), (B), in muffler body 18A, dispose respectively discoid the first dividing plate 181, second partition 182, thus, it is the first expansion chamber 183, the 3rd expansion chamber 184, the second expansion chamber 185 that muffler body 18A begins by zoning from vehicle front.
End of downstream side (end of rear view of vehicle side) at catalysing area 187 is connected with straight tube 188.Straight tube 188 is to insert logical the first dividing plate 181, say the state intercalation that is pressed into gently and the pipe part of hollow cylindrical between the first expansion chamber 183 and the 3rd expansion chamber 184 in more detail, the part of formation exhaust passageway.The straight tube 188 that one end of upstream side is connected with catalysing area, its other end is connected with the converged cone 189 of undergauge rearward.Adopt this structure, the exhaust gas of discharging from divergent cone 186 flows out to the rear of vehicle by straight tube 188 and converged cone 189 after catalysing area 187 purifies.
Affect the output characteristics of motor and the converged cone 189 of noise reduction characteristic, undergauge became before zoning goes out the second partition 182 of the second expansion chamber 185 to form mild taper, and extended near the second partition 182.And converged cone 189, its end of downstream side form roughly straight tubular and are supported in second partition 182.In the second expansion chamber 185, dispose the U font outlet pipe 190 for U word shape of being bent to form shown in Fig. 6 (B), the upstream side end of U font outlet pipe 190 is connected with the end of downstream side of converged cone 189.So that the flow direction of exhaust conversion 180 is spent, the other end of U font outlet pipe 190 is connected with the downstream side outlet pipe 191 that straight line shape extends U font outlet pipe 190 in the 185 interior bendings of the second expansion chamber.Downstream side outlet pipe 191, one end of its upstream side is connected with U font outlet pipe 190, extend to the first expansion chamber 183 by second partition 182, the first dividing plate 181, the other end in the downstream side of downstream side outlet pipe 191 is close to catalysing area 187, side by side exhaust gas.Adopt this structure, the exhaust gas that flows out to rear view of vehicle, by U font outlet pipe 190 conversion directions, forwards diffluence and in the 183 interior discharges of the first expansion chamber.
Next exhaust gas to the first expansion chamber 183 is discharged flows into the second expansion chamber 185.Shown in Fig. 6 (B), the first expansion chamber 183 is communicated with by being configured to the air pipe 192 parallel with the axis of outlet pipe 23 grades with the second expansion chamber 185.Thus, the exhaust gas from downstream side outlet pipe 191 is discharged to the first expansion chamber 183 flows into the second expansion chamber 185 that is positioned at vehicle rear.
And shown in Fig. 6 (B), the second expansion chamber 185 is communicated with by air pipe 193 with the 3rd expansion chamber 184.The exhaust gas of discharging to the second expansion chamber 185 thus, flows into the 3rd expansion chamber 184.Shown in Fig. 6 (A), the end of the discharge tube 18B that is communicated with the outside is in the 184 interior openings of the 3rd expansion chamber, and the exhaust gas that flows into the 3rd expansion chamber 184 is discharged to the outside by discharge tube 18B.That is, become the last expansion chamber that flows into of exhaust gas for baffler 18, the three expansion chambers 184.
Then, shape and coupled condition from the end of downstream side of outlet pipe 23 to each parts of downstream side outlet pipe 191 are elaborated, and these parts consist of the exhaust passageway in the muffler body 18A before will discharging to the first expansion chamber 183 from the exhaust gas that enters into the outlet pipe 23 in the muffler body 18A.Fig. 7 is the B-B sectional drawing of seeing from arrow B shown in Figure 5, and Fig. 8 is the C-C sectional drawing of seeing from arrow C shown in Figure 5.In addition, Fig. 9 is the sectional drawing of the baffler 18 seen from the axial direction of baffler 18.
As shown in Figure 7, outlet pipe 23 directly enters from about centre of the above-below direction of muffler body 18A.Fig. 9 (A) is the view of the D-D direction among Fig. 7, and as shown in this figure, outlet pipe 23 enters in the muffler body 18A from the centre of the overall width direction of baffler 18.Afterwards, outlet pipe 23 extends in the first expansion chamber 183 and is connected with above-mentioned divergent cone 186.
Fig. 8 is C-C sectional drawing shown in Figure 5, in more detail, be the sectional drawing (simultaneously with reference to Fig. 9 (B)) that the imaginary plane of central axis of central axis, the downstream side outlet pipe 191 of the involved central axis that outlet pipe 23 arranged of baffler 18, catalysing area 187 is cut open.Although in baffler 18, the central axis (L3) of the central axis (L1) of formation outlet pipe 23, the central axis (L2) of catalysing area 187, downstream side outlet pipe 191 is comprised in the position relationship in the same imaginary plane, but does not need to adopt such structure.
As shown in Figure 8, divergent cone 186 is the cone shape of decaptitating of rearward hole enlargement, the center of its side face towards vehicle interior side below (the arrow D direction among Fig. 9 (A)) gradually away from the central axis of outlet pipe 23.And, divergent cone 186, the state of the upstream-side-end of embedding catalysing area 187 and catalysing area 187 link beyond its end of downstream side, and afterwards, catalysing area 187 extends to the proximal most position of the first dividing plate 181.With the end of downstream side of the catalysing area 187 of the proximal most position that extends to the first dividing plate 181 by the form of the outer embedding of interior all end faces of straight tube 188 with catalysing area 187 and straight tube 188 chimeric bindings, this straight tube 188 is adapted to across between the first expansion chamber 183 and the 3rd expansion chamber 184.Straight tube 188 is inserted and is led in the inserting hole 181A of the first dividing plate 181, be to keep the airtight conditions between the expansion chamber, straight tube 188 with the state of close contact, be that its side face is intercalated in the first dividing plate 181 with the chimeric state that is pressed into gently this degree that interior week contacts and form of inserting hole 181A.Like this, catalysing area 187 with its upstream-side-end be connected with outlet pipe 23, its end of downstream side is supported with the state that straight tube 188 is connected, its side face is exposed in the first expansion chamber 183.Adopt such structure, owing to the heat of the high-temperature exhaust air gas of discharging to the first expansion chamber 183 is directly passed to the outer surface of catalysing area 187, so the preheating of catalysing area 187 can be done sth. in advance.In addition, although catalysing area 187 is in the condition of high temperature, but because it is chimeric with the form and the straight tube 188 that are covered by straight tube 188, and 188 slotting leading in the inserting hole 181A of the first dividing plate 181 of straight tube, therefore catalysing area 187 can directly not contact with the first dividing plate 181, can suppress the heat transmission from catalysing area 187 to muffler body 18A.
Fig. 9 (B) is the view of the E-E direction among Fig. 7, is the sectional drawing of cutting baffler 18 in the after a while side of the first dividing plate 181 open in more detail.Because catalysing area 187 is connected with divergent cone 186, and the center heart of the side face of diffusion centrum 186 towards vehicle interior side below gradually away from the central axis of outlet pipe 23, therefore, shown in Fig. 9 (B), the central axis of catalysing area 187 (L2) is in the position of the skew from the central axis (L1) of outlet pipe 23 to outer circumferential side (the arrow D direction Fig. 9 (A)).Therefore, be equipped with at vehicle 1 under the state of baffler 18, the axis L 2 (axle center) of catalysing area 187 is at vertical surface and the vehicle interior side between the horizontal plane and the downside of vehicle 1, and namely axis L 1 is positioned at vehicle interior side and downside relatively.
Then, in the 3rd expansion chamber 184, straight tube 188 forms in the dead astern of catalysing area 187 along the identical or roughly the same exhaust passageway of its internal diameter of specific length size and catalysing area 187, and the end of downstream side of straight tube 188 (dead astern) is connected with converged cone 189.Converged cone 189 is at the interior flow direction along exhaust gas of the 3rd expansion chamber 184 undergauge gently or gradually, and is connected towards the U of the 3rd expansion chamber font outlet pipe 190 with an end through second partition 182.And in this example, from the length of the distance of catalysing area 187 to U font outlet pipes 190, the exhaust passageway that namely formed by straight tube 188 and converged cone 189, straight tube 188 shared length are about about 1/3.In baffler 18, adopt this straight tube 188, for the exhaust gas of discharging from catalysing area 187, form along the identical or roughly the same exhaust passageway of its internal diameter of specific length size and catalysing area 187, can relax thus the back pressure rising that the converged cone 189 by the downstream side causes.In addition, in this example, although with straight tube 188 and converged cone 189 split settings, also they can be formed as one.
Then, U font outlet pipe 190 bends to U word shape, and in its end of downstream side and 191 combinations of downstream side outlet pipe.Downstream side outlet pipe 191 extends to the first expansion chamber 183, and discharges exhaust gas from its end of downstream side.Here, shown in Fig. 9 (B), owing in baffler 18, form the central axis (L1) of outlet pipe 23, the central axis of catalysing area 187 (L2), the central axis of downstream side outlet pipe 191 (L3) is comprised in the position relationship in the same imaginary plane, and the central axis of catalysing area 187 (L2) moves to the periphery lateral deviation from the central axis (L1) of outlet pipe 23, so the central axis of downstream side outlet pipe 191 (L3) is positioned at the opposition side of the central axis (L2) of catalysing area 187 across the central axis (L1) of outlet pipe 23.
And behind the first expansion chamber 183 discharge exhaust gas, as mentioned above, exhaust gas flows into the second expansion chamber 185, the 3rd expansion chamber 184, and finally discharges to the outside from discharge tube 18B from downstream side outlet pipe 191.Fig. 9 (C) is the view of the F-F direction among Fig. 7, more specifically, is the sectional drawing of cutting baffler 18 in the after a while side of second partition 182 open.As shown in this figure, air pipe 192, the air pipe 193 that is communicated with each expansion chamber is not adapted to not produce with catalysing area 187 and downstream side outlet pipe 191 etc. in muffler body 18A interferes.In addition, discharge tube 18B is adapted to its discharge side end and opens to the outside from the centre of the overall width direction of baffler 18, and exhaust gas is from discharging to the outside here.
As mentioned above, in this example, in baffler 18, straight tube 188 forms in the dead astern of catalysing area 187 along the identical or roughly the same exhaust passageway of its internal diameter of specific length size and catalysing area 187, and the end of downstream side of straight tube 188 (dead astern) is connected with converged cone 189.And converged cone 189 gently or little by little forms exhaust passageway in undergauge ground along the circulating direction of exhaust gas, make exhaust gas downstream effluent go out.By not forming converged cone section (diameter reducing part) in the dead astern of this catalysing area 187 like this, even do not form pore etc. at diameter reducing part, also can reduce the exhaust resistance (flow path resistance) of the positive downstream part of catalysing area 187.Therefore, need not to form pore etc., both had simple exhaust passageway structure, can suppress again the rapid rising of back pressure.
In addition, the form that catalysing area 187 is covered by straight tube 188 with its end of downstream side (by the form of outer embedding) and straight tube 188 are chimeric and link, and straight tube 188 intercalations are in the inserting hole 181A of the first dividing plate 181.Adopt this structure, although catalysing area 187 is in the condition of high temperature, because catalysing area 187 directly is not connected with the first dividing plate 181, therefore can suppress the heat transmission from catalysing area 187 to muffler body 18A.
In addition, although on straight tube 188 and catalysing area 187 binding sites, the part of straight tube 188 is exposed in the first expansion chamber 183 of high temperature, but its major part is configured in the 3rd expansion chamber 184, and this expansion chamber 184 is the last expansion chamber that flows into of exhaust gas in baffler 18.Because the temperature of exhaust gas becomes lower in as the 3rd expansion chamber 184 of the last expansion chamber that flows into of exhaust gas, the temperature rising of the straight tube 188 that therefore can suppress to cause because of the first expansion chamber 183 or catalysing area 187 itself, and can suppress through the heat transmission of the first dividing plate 181 to muffler body 18A.
More than example of the present invention is illustrated, yet the present invention is not limited in above-mentioned example.For example, in this example, baffler of the present invention is applied to scooter, but also can be applied at other motorcycle.
