【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、水中航走体の機関に適用される潤滑油、その
他、内燃機関一般に適用できる潤滑油に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lubricating oil that can be applied to engines of underwater vehicles and other lubricating oils that can be applied to internal combustion engines in general.
内燃機関、特に水中航走体の機関の摺動１回転部には潤
滑油が欠かせない。また機関室に海水が混入するため機
関部品の発錆が顕著に惹起するという問題があった。Lubricating oil is indispensable for internal combustion engines, especially for the sliding parts of engines of underwater vehicles. There was also the problem that seawater entered the engine room, causing significant rusting of engine parts.
機関の設計、構造上海水の混入が避けられないので、潤
滑油の海水に対する耐食性を向上することを図る必要が
あった。潤滑油には防錆添加剤が配合されているが、海
水混入を前提とした防錆性能は保証されていない。Since the contamination of seawater into the engine design and structure was unavoidable, it was necessary to improve the corrosion resistance of the lubricating oil against seawater. Lubricating oils contain anti-rust additives, but their anti-rust performance is not guaranteed even if seawater is mixed in.
従来、海水による鉄鋼の腐食を防止する上で。Conventionally, in preventing corrosion of steel by seawater.
りん酸塩、特に重合りん酸塩が有効であることがわかっ
ているが、無機物では潤滑油に不溶であり混入する事が
できない。Phosphates, especially polymerized phosphates, are known to be effective, but inorganic substances are insoluble in lubricating oil and cannot be mixed in.
本発明者等は、この知見に基づき天然原料で海面活性を
示すりん脂質のレシチンを潤滑油に添加すれば２期待の
防錆効果が得られる事を見い出し本発明をなすに至った
。Based on this knowledge, the present inventors discovered that if lecithin, a phospholipid that is a natural raw material and exhibits sea surface activity, is added to lubricating oil, two expected anti-rust effects can be obtained, and the present invention has been completed.
すなわち本発明は、内燃機関の潤滑油においてレシチン

る。That is, the present invention provides a lubricating oil for internal combustion engines, which is characterized in that lecithin is added thereto.

の接触を妨害して腐食を防止すると推定される。It is not clear whether the phosphorus in lecithin is acting, but when mixed with seawater, lecithin becomes a stable emulsion and covers the iron surface, or adsorbed water prevents direct contact with seawater and the atmosphere, preventing corrosion. It is estimated that

J! Add lecithin to the solution, stir and mix to prepare a test piece (5S
41) and heat to 95°C for 1 hour. Seawater was added and stirred, the heating was stopped, and the mixture was allowed to cool naturally. After 45 hours, the test piece was taken out and the state of corrosion was observed.
本試験の結果を表ＩＫ示す。The results of this test are shown in Table IK.

滑油の働きを阻害しないことも計測された。Table 1 Table 2 Although it differs with the amount added, it has become clear that y corrosion can be prevented if the amount is the same as the amount added to seawater. Furthermore, when 10% lecithin was added, the viscosity at 40° C. was 145 cst, and the coefficient of friction (1) was not much different from that of the initial lubricating oil, and it was also measured that (2) it did not inhibit the original function of the lubricating oil.
