- Corrosion inhibitors include, for example, benzotriazole and benzoimidazole Can be mentioned.
- the friction coefficient of the lubricating oil composition was determined using a reciprocating sliding friction tester [SRV friction tester] at a vibration frequency of 50 Hz, amplitude of 3 h, load of 25 N, temperature of 80 ° C, and test time. Measured at 25 minutes.
- SRV friction tester reciprocating sliding friction tester
- the oxidation test using air containing nitrogen oxide gas was performed on 150 ml of test oil at a temperature of 130 ° C, a nitrogen oxide (NO,) concentration of 1% by volume, a flow rate of 2 liters, and a test time of 8 hours.
- NO nitrogen oxide

- Comparative Examples 1 and 2 are lubricating oil compositions that contain component (A), component (B), component (D) and component (E) but do not contain component (C).
- C-MoDTC Oxymolybdenum sulfide - ⁇ , ⁇ -ditridecyldithirubbamate C, -ZnDTP ( ⁇ ⁇ ⁇ ): di-2-ethylhexyldithio flWMiifti
- the lubricating oil compositions of the present invention of Examples 1 to 10 all have a low coefficient of friction and good friction characteristics, and are heated at 1,30 ° C for 8 hours in the presence of nitrogen oxide gas. Even after oxidation, the coefficient of friction hardly changes, indicating that these lubricating oil compositions have good oxidation resistance.
- the lubricating oil compositions of Comparative Examples 1 and 2 which do not contain the sulfur compound (C) component, have a low coefficient of friction immediately after preparation, but have a low friction coefficient of 130 ° C. in the presence of nitrogen oxide gas. After heating and oxidizing at C for 8 hours, the coefficient of friction increases, indicating that the oxidation resistance is poor.
- the lubricating oil composition of the present invention has excellent properties by blending a specific structure of oxymolybdenum dithiocarbamate, zinc dialkyldithiophosphate, a sulfur compound, a metal-based detergent, and a boron-containing compound with a base oil. It has low abrasion resistance, and exhibits excellent oxidation resistance even at high temperatures and in the presence of nitrogen oxide gas, maintaining good friction characteristics (low friction).
- Internal combustion engine, automatic transmission, shock absorber, power It can be suitably used as a lubricating oil such as a steering oil, particularly a lubricating oil for an internal combustion engine.

Abstract
On prépare cette composition d'huile lubrifiante en mélangeant une huile de base lubrifiante avec un dithiocarbamate d'oxysulfure de molybdène à structure spécifique, un dithiophosphate de dialkyle de zinc, des composés soufrés, des détergents métalliques et des composés de bore. La teneur en molybdène provenant du dithiocarbamate, celle du phosphore provenant du dithiophosphate, celle du soufre des composés soufrés, celle des détergents et celle du bore, provenant des composés en contenant, sont respectivement de 200-2000 ppm, 0,02-0,15 % en poids, 0,02-0,30 % en poids, 1-10 % en poids et 0,005-0,06 % en poids de la composition d'ensemble. Celle-ci présente une excellente résistance à l'oxydation, n'est pas dégradée par des gaz contenant de l'oxyde d'azote et garde longtemps sa capacité à réduire les frictions dans les moteurs.
