Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to an engine for assembling a sound-absorbing tool, particularly for a chain saw or the like. The device, [Prior Art] ° The exhaust muffler used in the internal machine has long been known for a long time, and is mainly used in automobiles. For example, such as chain mines:: All of them, from the end of 1980, on the market, "the tool, the .. j pass the dry circumference is still 雈 Ϊ = gas is sent from a steam shovel :: Two of the exhausted gases are treated in an exhaust muffler and then discharged. Nearly: this carbon oxide or the like can be combined with many known kinds of oxidation catalysts to reduce sources such as hydrocarbons, and dyes. The present invention provides a The front exit type of catalyst eliminates the number of parts of the crying to save parts and weight, and simplifies the design. [Invention] The present invention includes - a device for assembling a silencer to the engine... ::- for receiving exhaust gas into the muffler a middle inlet, a second catalyst assembly, and a fixing device for fixing the muffler to the engine; a fastener tube cover for covering the fastener tube and including a row The outlet from which the gas exits. The outlet includes a directional guide for guiding the exhaust gas that is leaving. The fastener tube cover can be used to fix the maximum spark particle size of the exhaust gas that is leaving. , ^ will be explained below with reference to the drawings In the drawings, all the parts in the drawings are not necessarily in accordance with the actual proportions. Moreover, in the respective drawings, the same component symbol is 6 Ι 273163·I, which shows the same components.

A has to change the yoke and add a wrinkle operation to connect the spacers 119, 125 to the screen 122 and allow thermal expansion. Referring next to Fig. 2, an isometric view of an exhaust muffler is shown, showing a portion of the path taken by the exhaust. After passing through the catalyst group # 123 (see Fig. 1), the exhaust gas is located in a muffler housing 17〇. The muffler outer cover 131 is combined with the muffler body 110 to form the muffler housing 170. From the silencer.... The exhaust gas exits through the exhaust ports in the muffler cover 131, such as the first exhaust gas 彳i 61 and the second exhaust gas exhaust port 162. In the present embodiment, the exhaust ports are all located in a pocket 175 1273163, which also includes a first tight inlet port 138 of the first fastener tube 137 (see the figure and the second fastener tube 14 (see) The second fastener enters = 埠 (4) (see figure). When the exhaust exits the muffler housing (7) and passes: the spark stop 149 0, the bladder 175 provides a volume. The gas passes through the spark stop 丨 49 At the time, the row of the outer moss 152 is crying + Liao 曰 enters a volume by a fastener pipe I:: two: This is the space between the muffler cover (3) virtual I, the firmware pipe cover 152 /, Nisko ^ Fastener pipe fittings cover 152 is designed to be used when the exhaust gas leaves the silencer to cry... to control its direction and spread - degree, the second parameter proposed by the 35 == 疋 by the USDA The Automobile Engineering Association established the Zhisen Titanium River to take the door, J.

Referring to Figure 1, there is shown a first-fastener tube 13: the degree: (4), in this embodiment, the tight/two fastener tubes are fixed to the engine. Each fastening (four) pieces 夂I Yes: used to silence the silencer such as 138 and 141), use the mouth, and the firmware inlet 埠 (for example, use the 乂 face to return the 聱, the sundial (for example, 139 * mm m ', not the firmware exit) '^ face the engine °-Fastener 143 screw 1273163 Rotating through the first fastener pipe fittings 13, 7 、 、, 士 π ^. After a jump and tightened to the engine. Similarly, the brother of a spear 'firm 146 spiral through the third prisoner The pipe member 14 is fastened to the engine. In the present embodiment, the fasteners are bolts, bran, or alternatively Such as screws, etc..., the silencer is attached to the engine. The other fastening devices of the year' will be due to the internal engine vibration, plus W + from the Μ A table thermal cycle leading to the shrinkage and expansion of the metal silencer, making direct 亍Straight women's wear to small engines will produce slack after a period of time. 〇〇_ _ Ma solved this problem, has proposed a method is to use flange fittings ten ^ For example, a fastener pipe fittings 137 盥 brother a fastener pipe fittings 14〇. This “sliding door” 2 convex, 彖 & parts can significantly reduce the squeezing of the clothing I, the firmware (such as the first fastener 143 盥 〆 〆, brother one fastener 146) Genus 1. Fastener fittings can also be used with this 保 4 fasteners without the influence of exhaust gases in the diffusion. Another type of fastener tube, time-of-day, :: ground reduction mounting fasteners are exposed to the heat of the catalyst. In addition, the muffler body (10) can be clamped to the outside of the muffler using the sharpening member h31J: However, when the fastener pipe fitting is used, the firmware pipe fitting provides a problem for the retracting of the ore. This tight debris can cause many problems. —Receiving lco in the 疋, use an outer cover such as the outer tube 152 of the fastener fitting to prevent the 盍 ^ ^ from entering the fastener fitting. In the present invention, in addition to preventing the debris from entering the inside of the cover, it can also be used as an exhaust outlet for the outside of the (fire) member. #五^ 4 These multiple uses can reduce the number of parts required for silence and crying, so that the group can be simplified. In this embodiment, the fastener W ^ is placed on the cover 152. On the front of the silencer, 1273163 can make the spark stop 149 more beautiful. 155, the test is that the fastener pipe cover 152 cannot be found. An outlet outlet 155==piece fitting cover 152 is provided. In the present embodiment, in this example, the deflecting plate 158 may also contain H from the other, and the other cover 152 may also include one. Outside the fastener fittings As can be seen from Figure 3, it helps to guide the exit of the exhaust. The design can be tilted at the two-piece tubular cover 152.
