この考案は、エンジンの排気管連結装置の改良
に関する。[Detailed Description of the Invention] This invention relates to an improvement of an exhaust pipe coupling device for an engine.
一般に、エンジンの排気孔端には、排気管の先
端に設けたフランジを合せ、排気管先端と排気孔
端の間にガスケツトを挾み、フランジをボルトで
排気孔端に締着して連結している。排気管は常に
高温の排気ガスが通るので、エンジンの排気孔部
分より高温になり、この熱が排気孔に伝つて、排
気孔が高温になる。特に空冷エンジンでは、排気
孔端にフランジが重つて、冷却が十分にできず排
気孔が過熱する不都合がある。 Generally, a flange provided at the tip of the exhaust pipe is connected to the end of the engine exhaust hole, a gasket is placed between the end of the exhaust pipe and the end of the exhaust hole, and the flange is tightened to the end of the exhaust hole with bolts. ing. Because high-temperature exhaust gas always passes through the exhaust pipe, it becomes hotter than the exhaust hole of the engine, and this heat is transferred to the exhaust hole, making the exhaust hole hotter. Particularly in air-cooled engines, the flange overlaps the end of the exhaust hole, resulting in insufficient cooling and overheating of the exhaust hole.
この考案は、かかる点に鑑み改善したもので、
以下図面に示す本考案の実施例について説明す

Embodiments of the present invention shown in the drawings will be described below.

１の端面に締着して連結する。 The figure shows the case of a 2-stroke engine.
The exhaust hole 1 is bored in the cylinder 2 of the engine, and the cylinder 2 has a large number of cooling fins 3 on its outer periphery.
is provided, and the cylinder 2 is cooled by blowing air onto the cooling fins 3. According to the present invention, the tip of the exhaust hole 1 is formed into a tapered hole 4, and a tapered annular gasket 5 made of a heat insulating material is inserted therein. On the other hand, a tapered pipe 8 having a flange 7 at the rear end is welded to the tip of the exhaust pipe 6. A gap 9 is formed between the exhaust pipe 6 and the tapered pipe 8. The exhaust pipe 6 is connected by inserting a tapered pipe 8 into the taper hole 4 of the exhaust hole 1 and tightening a bolt 10 passed through the flange 7 to the end face of the exhaust hole 1.
作用について説明する。 The effect will be explained.
エンジンを運転すると、シリンダ２内で燃焼し
た排気ガスは、排気孔１から排気管６へ流れる。
ところで排気ガスが排気孔１に滞留する時間は一
瞬であるが、排気管６は長いので滞留する時間が
長く、排気管６が排気孔１の部分により高温にな
る。この熱は、排気孔１側に流れようとするが、
排気管６は、テーパー管８で、排気管６の先端部
分まで隙間９があり、隙間９に冷却空気が流れる
ことができるので、冷却が促進でき、排気孔１へ
流れる熱を少くして、排気孔１の過熱を防ぐこと
ができる。又、ガスケツト５は、断熱材で熱が伝
わり難く、テーパー状の締合せであるので、締付
けが確実にできて、排気ガスの洩れも起き難い。 When the engine is operated, exhaust gas burned in the cylinder 2 flows from the exhaust hole 1 to the exhaust pipe 6.
By the way, although the exhaust gas stays in the exhaust hole 1 for only a moment, the exhaust pipe 6 is long, so it stays there for a long time, and the temperature of the exhaust pipe 6 becomes higher than that of the exhaust hole 1. This heat tries to flow to the exhaust hole 1 side, but
The exhaust pipe 6 is a tapered pipe 8, and there is a gap 9 up to the tip of the exhaust pipe 6. Cooling air can flow through the gap 9, so cooling can be promoted and the heat flowing to the exhaust hole 1 can be reduced. Overheating of the exhaust hole 1 can be prevented. In addition, the gasket 5 is a heat insulating material that does not easily transmit heat, and since it is tapered, it can be tightened reliably and exhaust gas is unlikely to leak.

る。 As explained above, this idea involves welding the tip of a tapered pipe with a flange at the rear end to the tip of the exhaust pipe, creating a gap between the exhaust pipe and the tapered pipe, and making it possible to close the tip of the engine exhaust hole. A tapered annular gasket is inserted as a tapered hole, and a tapered pipe is inserted into the gasket and the flange part is tightened, so cooling air can flow into the gap between the tapered pipe and the exhaust pipe, and the exhaust pipe It is possible to cool down to the tip of the exhaust hole, promoting cooling and preventing overheating of the exhaust hole. In addition, the tapered tightening allows the tightening force to be increased, making it difficult for exhaust gas to leak.
