いようにして、小型エンジンにも装着できるサーマルリ
アクタとしたもので、以下図面に示す本考案の実施例に
ついて説明する。This invention is a thermal reactor that can be installed even in small engines by keeping the exhaust pipe length the same and making it difficult to cool down the exhaust heat.The following describes an embodiment of the invention shown in the drawings.
エンジン1の排気孔2に連結する排気内管3の外側に隙
間を設けて排気外管4を設け、排気外管4の先端を広げ
て、セラミック等の断熱体5を排気内管3と排気外筒4
との間に入れる。An exhaust outer pipe 4 is provided with a gap on the outside of the exhaust inner pipe 3 connected to the exhaust hole 2 of the engine 1, the tip of the exhaust outer pipe 4 is widened, and a heat insulator 5 such as ceramic is connected to the exhaust inner pipe 3 for exhaust air. Outer cylinder 4
Put it between.
6はガスケット、7は締着リングである。6 is a gasket, and 7 is a fastening ring.
キーマルリアクタ8は、前後端が細くできていて、前端
は、排気内管3の後端に溶着する。The keymal reactor 8 has narrow front and rear ends, and the front end is welded to the rear end of the exhaust inner pipe 3.
又、リアクタ8の外周は間隔を設けてリアクタ外筒9で
覆い、リアクタ外筒90前後にセラミック等の断熱筒1
0を軸方向に隙間があるように挿入し、リアクタ8を断
熱筒10で保持する。In addition, the outer periphery of the reactor 8 is covered with a reactor outer cylinder 9 at intervals, and a heat insulating cylinder 1 made of ceramic or the like is placed before and after the reactor outer cylinder 90.
0 is inserted so that there is a gap in the axial direction, and the reactor 8 is held by the heat insulating cylinder 10.
11はグラスウール等の保温材、12はガスシールリン
グ、13は断熱材である。11 is a heat insulating material such as glass wool, 12 is a gas seal ring, and 13 is a heat insulating material.
リアクタ外筒9の前端は、排気外筒4に巻きバンド14
によって連結する。The front end of the reactor outer cylinder 9 is wrapped around the exhaust outer cylinder 4 with a band 14.
Concatenate by.
そして、リアクタ外筒9の後端には、マフラ筒15を挿
入し、ガスケット16を介して締着バンド17で連結す
る。A muffler tube 15 is inserted into the rear end of the reactor outer tube 9 and connected with a fastening band 17 via a gasket 16.
伺、マフラ筒15は保持部18を車体に固定する。The muffler tube 15 fixes the holding part 18 to the vehicle body.
作用について説明する。The effect will be explained.
エンジン1の排気孔2から排出する排気ガスは、排気内
管3へ入る。Exhaust gas discharged from the exhaust hole 2 of the engine 1 enters an exhaust inner pipe 3.
排気内管3は、隙間を設けて排気外管4に覆われていて
、空気層で断熱されているので、排気ガスの温度低下が
少い。Since the exhaust inner pipe 3 is covered with the exhaust outer pipe 4 with a gap and is insulated with an air layer, the temperature drop of the exhaust gas is small.
又、排気外管4の先端には断熱体5が挿入されているの
で、排気内管3から排気外管4に熱が伝わって逃げない
。Further, since the heat insulator 5 is inserted at the tip of the exhaust outer pipe 4, heat is not transferred from the exhaust inner pipe 3 to the exhaust outer pipe 4 and does not escape.
こうして、排気ガスは高い温度のままりアクタ8内に入
り、膨張して暫時滞留し、燃焼して有害成分が少くなる
。In this way, the exhaust gas enters the actuator 8 while remaining at a high temperature, expands and stays for a while, and is combusted to reduce harmful components.
そして、マフラ筒15へ流れて消音して放出される。Then, it flows into the muffler tube 15, where it is muffled and discharged.
リアクタ8は、前端が排気内管3に固定され、熱によっ
て後方に膨張して伸びるが、断熱筒10とリアクタ外筒
9との間に軸方向の隙間があるので、この伸びを許容す
る。The front end of the reactor 8 is fixed to the exhaust inner pipe 3, and it expands and stretches rearward due to heat, but this expansion is allowed because there is an axial gap between the heat insulating cylinder 10 and the reactor outer cylinder 9.
以上説明したように、この考案は、排気内管と排気外管
の先端に断熱体を入れて隙間を設けた二重管とし、排気
内管の後端にリアクタの前端を溶着し、排気外管の後端
にリアクタ外筒の前端を巻きバンドで締着し、リアクタ
外筒の前後に軸方向の隙間があるように断熱筒を挿入し
、該断熱筒にリアクタの前後を支承させ、リアクタ外筒
の後端にマフラ筒を連結するようにしたので、排気ガス
を温度の低下を少くしてリアクタまで導くことができ、
リアクタで燃焼させて浄化できる。As explained above, this idea consists of a double pipe with a gap between the inner exhaust pipe and the outer exhaust pipe by inserting a heat insulator at the ends, and the front end of the reactor is welded to the rear end of the inner exhaust pipe. Wrap the front end of the reactor outer cylinder around the rear end of the tube and tighten it with a band. Insert the heat insulating cylinder so that there is an axial gap at the front and rear of the reactor outer cylinder. Since the muffler tube is connected to the rear end of the outer tube, the exhaust gas can be guided to the reactor with less temperature drop.
It can be purified by combustion in a reactor.
又、燃焼熱でリアクタが伸びても、断熱筒に軸方向隙間
があって許容できる。Furthermore, even if the reactor expands due to combustion heat, this can be tolerated because there is an axial gap in the heat insulating cylinder.
そして、リアクタの長さだけ排気管を短くすれば、大型
にiることもなく、オートバイ等の小型エンジンに装着
できる。If the exhaust pipe is shortened by the length of the reactor, it can be installed in a small engine such as a motorcycle without increasing the size.
