近年、内燃機関における熱損失を低減さ亡て、エネルギ
効率を向上させる目的で、燃焼室周辺を断熱することが
種々検討されているうその一つとしてシリンダの断熱化
がある。シリンダ部位における熱損失は非常に大きく、
その断熱化によってもたらされる熱損失の低減率が大で
あり、エネルギ効率の向上に大きく貢献することから、
この断熱化は各方面にて検討されている。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylinder for an internal combustion engine, and particularly to a cylinder that has not only wear resistance and seizure resistance on the sliding surface with a piston, but also heat insulation properties. In order to reduce heat loss and improve energy efficiency, one of the various methods being considered is to insulate the combustion chamber around the combustion chamber, which involves insulating the cylinder. The heat loss in the cylinder part is very large.
The reduction rate of heat loss brought about by insulation is large, and it greatly contributes to improving energy efficiency.
This insulation is being studied in various fields.
このシリンダの断熱化の手段として最も一般的に行なわ
れているのは、シリンダライナを従来の鋳鉄などの金属
材料に代えである椎のセラミック材料によって構成する
という手段であり。The most commonly used means for insulating the cylinder is to construct the cylinder liner from a ceramic material instead of the conventional metal material such as cast iron.
該手段によれば、熱損失をかなり低減しうるが。Although by this measure the heat losses can be reduced considerably.
一方において、次のような問題点があり、実用的なもの
とは云えない。すなわち、
（１） シリンダライナ材料には、高い機械的強度、
耐摩耗性および耐衝撃性が要求されるが、これらの特性
を満足させるＫはセラミック材料としてＳｉ３Ｎ、また
はＳｉＣなどの高級材を必要とし、コスト的に相描高価
になるととも釦、それらの耐久は顕性も充分に確立され
ていない。On the other hand, it has the following problems and cannot be said to be practical. That is, (1) the cylinder liner material has high mechanical strength,
Abrasion resistance and impact resistance are required, but K that satisfies these properties requires high-grade materials such as Si3N or SiC as a ceramic material, which increases the cost and reduces the durability of buttons and The manifestation of this disease has not been fully established.
（２） シリンダライナは、外周部はシリンダブ日ツ
クとの嵌合、内周部はピストンとの摺動に供されるもの

度が要求されるほか、内周面については良好な表面粗度
も必要となる。しかしながら、セラミック材料は一般に
加工が峻しいことから、高い製造技術が必要であり、ま
た生産性も低い。(2) Since the outer circumference of the cylinder liner is used for fitting with the cylinder tab and the inner circumference for sliding on the piston, high dimensional accuracy is required for both the outer and inner circumferential surfaces. In addition, good surface roughness is also required for the inner peripheral surface. However, since ceramic materials are generally difficult to process, advanced manufacturing techniques are required, and productivity is also low.
ｆ３） ５１３Ｎ、またはＳｉＣなどのセラミック材

ク材料を用いて製造されるシリンダライナと金属材料を

能の低下をきたす。f3) Ceramic materials such as 513N or SiC have lower thermal and expansion coefficients than metal materials, and are suitable for cylinder liners manufactured using ceramic materials and pistons (or piston rings) manufactured using metal materials. A considerably large rearance is required between the two, resulting in a decrease in engine performance.
また、このようにシリンダライナ全体をセラミック材料

られていないのが現状である。In addition, instead of constructing the entire cylinder liner from ceramic material, research is being conducted into forming a ceramic layer on the inner circumferential surface of the cylinder using coating methods such as thermal spraying, but there is only one conventional method. Since it is a single ceramic layer made of two ceramic materials, it is currently not possible to obtain a cylinder that satisfies the requirements for various properties.

The object is to provide a cylinder for an internal combustion engine that does not cause the various problems described above and can simultaneously satisfy the various characteristics described above even by using a ceramic material. The present kJAa has a cylinder body made of a metal material, a ceramic layer is formed on the inner circumferential surface of the cylinder body, and the ceramic layer is two layers, and 10 of the two layers, that is, the sliding surface. The layer is mainly composed of a ceramic material that provides wear resistance,
The other layers are mainly made of a ceramic material that provides heat insulation properties, and a bonding material layer is interposed that is made of a material that enhances the bond between the metal material and the ceramic material and has a coefficient of thermal expansion intermediate between the two materials. It is characterized by having a dead structure. In this case, each layer provided on the inner peripheral surface of the cylinder body is formed by various types of thermal spraying, such as plasma spraying.

撃性の低下を抑制できるうAccording to the present invention, since the cylinder is made of not only a metal material but also a ceramic material, the heat insulation properties of the cylinder are improved. Furthermore, since the cylinder body, which occupies most of the cylinder, is made of metal, a ceramic material is used to compensate for the difference in thermal expansion between the cylinder and the piston, which is a sliding member (the piston ring is also sensitive). However, you don't need to think about it too much. Two types of materials are used as the ceramic material, each material constitutes a ceramic layer, and one of the ceramic layers is mainly responsible for heat insulation, and the other layer is mainly responsible for wear resistance. This allows you to freely select the most suitable material for each characteristic from a wide range of ceramic materials, and also greatly improves each characteristic of the cylinder. , increase the bonding properties of these materials b
By interposing a bonding material layer made of a material that absorbs the difference in thermal expansion, that is, a material with a coefficient of thermal expansion intermediate between that of metal and ceramic materials, the impact resistance of the cylinder is prevented from decreasing. I can do it
