Abstract

<P>PROBLEM TO BE SOLVED: To provide a lubricating oil additive capable of increasing efficiency in fuel combustion and consumption by keeping low the friction loss of internal combustion engine lubricating oil even after a prolonged use and capable of extensively purifying dangerous substance-containing exhaust gas, for improving the global environment, for decreasing the ill effects on human health, and for improving combustion technologies in compliance with criteria more rigorous than those in the past, under the circumstances where dangerous substance-containing exhaust gas from petroleum fuel combustion in internal combustion engines aboard gasoline-powered automobiles is causing atmospheric pollution for the production of endocrine disrupters to the detriment of human health, for the generation of photochemical smog, and for the deterioration of the global environment in general because of carbon dioxide on the increase. <P>SOLUTION: The lubricating oil additive used for internal combustion engines is a mixture containing siloxane or the like. The additive, when mixed with the internal combustion engine lubricating oil, keeps friction loss low and improves combustion efficiency, thereby extensively removing dangerous substances out of exhaust gas, such as carbon monoxide, hydrocarbons, and nitrogen oxides. A great improvement is achieved also in fuel consumption efficiency. <P>COPYRIGHT: (C)2004,JPO&NCIPI

従来の技術は、地球温暖化の一因とされる大気中の^ＣＯ ^２濃度の抑制や省資源の観点から、ガソリン自動車用エンジン等の内燃機関に対して、耐摩耗性、酸化安定性、清浄分散性などの性能の他に省燃費性を追求したものであった。
【０００３】
【発明が解決しようとする課題】
しかしながら、以上の従来技術によれば排出ガス削減ができず、地球環境悪化に歯止めがかからなく社会問題になり、より有効な発明が待望されている。そこでこの発明は、より一段の長時間の使用後においても内燃機関用潤滑油の摩擦損失を低く維持することによる省燃費化と、排気ガス中の有害物質の大幅な浄化を目指した新たな内燃機関用潤滑油の添加剤を提供することを課題とする。

以上の課題を解決するために、請求項１の発明は内燃機関用潤滑油にシロキサンを骨格をし、ホウ素（^Ｂ）を導入し、これに無機系酸化物（Ｃｕ、Ｆｅ、Ｍｎ）と酸化セリウム、シリカ、タルク、二酸化チタンを添加せしめることを特徴とする潤滑油の長寿命化と排気ガス中の有害物質を大幅に浄化する添加剤である。
【０００５】
【発明の実施の形態】
この発明で使用する添加剤基材は、シロキサン骨格にホウ素（^Ｂ）を導入したボロジフェニルシロキサンポリマーである。このようなボロジフェニルシロキサンポリマーは、市販されているポリマーを利用することができ、例えば菱電化成（株）製の商品名ミオサーモ^Ｖ９４０−７０等が挙げられる。

添加剤基材としてのボロジフェニルシロキサンポリマーには、無機系^Ｃｕ、^Ｆｅ、^Ｍｎ、酸化セリウム、シリカ、タルク、二酸化チタン等の酸化物を添加・混合する。これらの無機系酸化物の粒径は、例えば０，０１〜１μ^ｍが望ましい。
【０００７】
本発明において、ボロジフェニルシロキサンポリマーと無機系酸化物の配合割合は、例えばボロジフェニルシロキサンポリマー１００重量部に対して無機系酸化物２０〜１００重量部、好ましくは３０〜６０重量部がよい。

以下本発明の実施例により更に説明する。ボロジフェニルシロキサンポリマー（菱電化成（株）製商品名ミオサーモ^Ｖ９４０−７０、不揮発成分７０％、重合度５０００、２０℃における粘度２５センチポイズ）に対して、無機系酸化物（平均粒径０，０５μ^ｍ）を３０重量％配合した。両者をよく混合することにより、添加剤を調製することができた。この添加剤を加えた潤滑油でガソリンエンジンの排気濃度試験を実施した。結果を下記表１に示す。
【表１】

上記の表より、本発明の潤滑油添加剤は排気ガス中の有害物質である^ＣＯ、^ＨＣが大幅に減少している、又、^ＣＯ２は増加していることにより完全燃焼が起こり、燃焼効率は向上していることを確認できた。
【０００９】

本発明は、特定の混合比を用いて得られるシロキサンの混合生成物であり、内燃機関用潤滑油の添加剤として用いた場合、長期間の使用においても低い摩擦損失を維持できるため省燃費化にも格段の効果を有し、排気ガス中の有害物質を大幅に浄化を達成するものである。[0001]
