Description
本発明は、内燃機関用のエンジン油組成物に関する。更に詳しくは、本発明は、優れた酸化安定性を持ち、劣化によってオイルの粘度上昇を引き起こさないエンジン油組成物に関する。 The present invention relates to an engine oil composition for an internal combustion engine. More particularly, the present invention relates to an engine oil composition that has excellent oxidation stability and does not cause an increase in oil viscosity due to deterioration.
自動車のエンジン油に求められることは、エンジン内部の潤滑を行い、清浄性を保つ機能に加え、近年の環境問題より、排ガス触媒を被毒させないエンジン油や省燃費機能を持つエンジン油等が求められている。こうした新しく求められている機能の中で、省燃費機能については、例えば、エンジン油の粘度を下げて粘性抵抗を少なくする方法や、有機モリブデン等を配合して潤滑時の摩擦係数を下げる方法等により、エンジン内部のエネルギー損失を少なくして対応してきた。 What is required of automobile engine oil is that, in addition to the function of lubricating the inside of the engine and maintaining cleanliness, engine oil that does not poison exhaust gas catalysts and has fuel saving functions are required due to recent environmental problems. It has been. Among these newly demanded functions, the fuel saving function includes, for example, a method of reducing the viscosity of engine oil to reduce the viscosity resistance, a method of reducing the friction coefficient during lubrication by blending organic molybdenum, etc. As a result, energy loss inside the engine has been reduced.
エンジン内の燃焼によって生じる排気ガスには、窒素酸化物（ＮＯｘ）、硫黄酸化物（ＳＯｘ）等が含まれており、これらの有害物質は、環境汚染、自然破壊、人体への悪影響等を引き起こすことが知られている。そこで排ガス触媒の改良等が行われてきたが、エンジン油に含まれるリン成分や硫黄成分は、排ガス触媒を被毒することが知られており、エンジン油内のリン成分や硫黄成分を削減することが必要になってきた。 The exhaust gas generated by combustion in the engine contains nitrogen oxides (NOx), sulfur oxides (SOx), etc., and these harmful substances cause environmental pollution, natural destruction, adverse effects on the human body, etc. It is known. Therefore, exhaust gas catalysts have been improved, but it is known that phosphorus and sulfur components contained in engine oil poison the exhaust gas catalyst, reducing phosphorus and sulfur components in engine oil. It has become necessary.
具体的にエンジン油内のリンを削減するということは、亜鉛ジチオホスフェートの含量を低減させるということである。亜鉛ジチオホスフェートは、耐摩耗性や酸化防止性を持つ添加剤であり、亜鉛ジチオホスフェートの削減は、エンジン油の耐摩耗性や酸化防止性の低下を引き起こす。耐摩耗性や酸化防止性は、配合の工夫や他の添加剤等で補うこともできたが、エンジン油の酸化劣化に伴い、エンジン油の粘度が上昇するという現象を抑えることはできなかった。エンジン油粘度の上昇は、エンジン油に含まれる成分の劣化や重合等によって引き起こされ、亜鉛ジチオフォスフェートを削減したエンジン油においては、粘度上昇が著しく大きくなる傾向にあった。 Specifically, reducing phosphorus in engine oil means reducing the content of zinc dithiophosphate. Zinc dithiophosphate is an additive having wear resistance and antioxidant properties, and reduction of zinc dithiophosphate causes a decrease in wear resistance and antioxidant properties of engine oil. Abrasion resistance and antioxidant properties could be compensated for by blending ingenuity and other additives, but it was not possible to suppress the phenomenon that the viscosity of the engine oil increased with the oxidative degradation of the engine oil. . The increase in the viscosity of the engine oil is caused by deterioration or polymerization of components contained in the engine oil, and the increase in the viscosity tends to be remarkably increased in the engine oil in which zinc dithiophosphate is reduced.
エンジン油の粘度が上昇すると、エンジン内の粘性抵抗が増えるため、エンジン油の粘度を下げて粘性抵抗を少なくするという効果が低下する。それにより、エンジン油に求められている省燃費機能も低下してしまった。そこで低リン、低硫黄処方のエンジン油が劣化しても、粘度上昇しないエンジン油が求められてきた。 When the viscosity of the engine oil increases, the viscosity resistance in the engine increases, so the effect of decreasing the viscosity resistance by decreasing the viscosity of the engine oil is reduced. As a result, the fuel saving function required for engine oil has also been reduced. Accordingly, there has been a demand for an engine oil that does not increase in viscosity even when engine oil with a low phosphorus and low sulfur prescription is deteriorated.
そこで特定の硫黄化合物とアミン系酸化防止剤との組み合わせにより、粘度上昇を防止する方法（例えば、特許文献１を参照）や、カルボン酸系分散剤と硼酸系分散剤の組み合わせにより、粘度上昇を防止する方法（例えば、特許文献２を参照）、金属塩清浄剤の組み合わせにより、潤滑油寿命を延ばして粘度上昇を防止する方法（例えば、特許文献３を参照）等が知られている。しかし特許文献１の方法は、硫黄化合物が増加してしまうという問題と共に、リン含量を削減したエンジン油では、粘度の上昇を防止する効果が不十分であった。また、特許文献２、３の方法では、リン含量を削減したエンジン油の粘度上昇を防止する効果が不十分であり、更に、耐磨耗性等のエンジン油に求められる基本的な性能も不十分であった。 Therefore, the viscosity increase can be achieved by combining a specific sulfur compound and an amine antioxidant to prevent the viscosity increase (see, for example, Patent Document 1) or by combining a carboxylic acid dispersant and a boric acid dispersant. There are known a method for preventing (see, for example, Patent Document 2), a method for extending the life of a lubricating oil and preventing an increase in viscosity by a combination of metal salt detergents (for example, see Patent Document 3), and the like. However, the method of Patent Document 1 has an insufficient effect of preventing an increase in viscosity with an engine oil with a reduced phosphorus content, together with a problem that sulfur compounds increase. In addition, the methods of Patent Documents 2 and 3 are insufficient in preventing the increase in viscosity of engine oil with a reduced phosphorus content, and further, basic performance required for engine oil such as wear resistance is not satisfactory. It was enough.
従って、本発明が解決しようとする課題は、低リン、低硫黄処方のエンジン油であっても、従来のエンジン油と同等又はそれ以上の酸化安定性、耐摩耗性、及び低摩擦性能を有し、劣化によってエンジン油粘度が上昇しないエンジン油組成物を提供することにある。 Therefore, the problem to be solved by the present invention is that even an engine oil with a low phosphorus and low sulfur formulation has oxidation stability, wear resistance, and low friction performance equivalent to or higher than those of conventional engine oils. And providing an engine oil composition in which the engine oil viscosity does not increase due to deterioration.
そこで本発明者等は、低リン処方のエンジン油について鋭意検討し、特定の構造のエステル化合物を配合することにより、低リン処方であっても、耐摩耗性、酸化防止性、持続性及び低摩擦性能に優れ、劣化しても粘度上昇しない、省燃費効果に優れたエンジン油を提供できることを見出し、本発明に至った。 Therefore, the present inventors have intensively studied an engine oil having a low phosphorus prescription, and by blending an ester compound having a specific structure, even with a low phosphorus prescription, the wear resistance, antioxidant property, sustainability and low The present inventors have found that an engine oil having excellent friction performance, no increase in viscosity even when deteriorated, and excellent fuel economy can be provided.

When these components are added, the phosphorus concentration increases, but the phosphorus concentration relative to the entire engine oil composition is preferably 500 ppm or less. Moreover, 3000 ppm or less is preferable and, as for the sulfur concentration of the whole engine oil composition of this invention, 2500 ppm or less is more preferable.

スラッジ量については０．１ｇ未満であれば良好な酸化安定性があると判断できるので、本発明品は全て良好な酸化安定性を有していることがわかる。また、平均摩擦係数は０．１以下であれば低摩擦エンジンオイルと呼ばれることから、本発明品は全て低摩擦性能を有していることがわかる。更に、磨耗痕は０．３ｍｍ未満であれば良好な耐磨耗性を示しているといえるので、本発明品は全て良好な耐摩耗性を有していることがわかる。そして、本発明品の劣化後の粘度については明らかに上昇が抑えられている。以上の結果から本発明のエンジン油組成物は、酸化安定性、低摩擦性、及び耐磨耗性が良好で、劣化してもオイルの粘度が上昇しないエンジンオイルであることが確認された。 If the amount of sludge is less than 0.1 g, it can be judged that there is good oxidation stability, so it can be seen that all the products of the present invention have good oxidation stability. In addition, if the average coefficient of friction is 0.1 or less, it is called a low friction engine oil. Therefore, it can be seen that all the products of the present invention have low friction performance. Furthermore, it can be said that if the wear scar is less than 0.3 mm, it shows good wear resistance, so that all the products of the present invention have good wear resistance. And as for the viscosity after degradation of the product of the present invention, an increase is clearly suppressed. From the above results, it was confirmed that the engine oil composition of the present invention is an engine oil that has good oxidation stability, low friction properties, and wear resistance, and does not increase in viscosity even when deteriorated.
