等々の欠陥があり、セラミツクスエンジンに用い
る問題がある。 In order to improve thermal efficiency, it is desirable that the head gasket used in a ceramic engine be made of a heat-resistant material and that the heat loss inside the combustion chamber be minimized.However, with conventional gaskets, the temperature within the combustion chamber is When the temperature reaches ℃, the thermal deformation caused by the high temperature is large, and since the heat conductivity is high, the heat inside the combustion chamber is easily transferred to the outside, and there are defects such as large heat loss at the gasket surface, etc. There is a problem with using it.
本考案は斯様な常況に着目して案出したのであ
つて、セラミツクスエンジン用ヘツドガスケツト

The second embodiment shown in FIG.
It is composed of a ceramic ring 4a and a metal ring 4b made of the same material as the fire ring of the first embodiment, and these rings 4a and 4b are combined with each other with the ceramic ring 4a inside, and the outside of the outer metal ring 4b is A locking groove 5 is formed at the end 4', and the edging part 3 is fitted into the locking groove 5, which is assembled into the gasket body.
The gasket body 1 and the cylinder hole 2 are separated from each other by the gasket body 1 and the cylinder hole 2.

ト本体に伝わりにくくなり、従つて、ガスケツト
本体の熱変形を防ぐことができる。Effects of the invention According to the invention, a fire ring made of ceramics is attached to the gasket body, and
This isolates the gasket body from the cylinder hole, making it difficult for high heat within the cylinder hole to be transmitted to the gasket body, thereby preventing thermal deformation of the gasket body.
また、フアイヤリングによつて熱伝導を防ぐか
ら熱損失が生じないので、エンジンの機能が損わ
れることはない。 Further, since the fire ring prevents heat conduction, no heat loss occurs, so the engine function is not impaired.
