Embodiment 1

[0079] Mix 20 g of polyol ester (lubricating machine oil, manufactured by Castrol Corporation, trade name: AISM CHICSUK) and 0.04 g of YUSILAB (trade name, organometallic, manufactured by Yushiro Chemical Co., Ltd.) to prepare a lubricant composition and store it in a container middle. Next, 30 g of HFC-134a was injected into the above-mentioned lubricant composition as a mixed refrigerant. The kinematic viscosity of this mixed refrigerant is 46m 2 / s. In addition, kinematic viscosity is measured on the temperature condition of 40 degreeC based on standard ASTM D445.

Embodiment 2

[0081] A lubricant composition was prepared by mixing 200 g of ECOSTAGE (trade name, lubricating engine oil, manufactured by Nippon Oil Corporation) and 2 g of YUSILAB, and this was used as a lubricating oil for an internal combustion engine. The kinematic viscosity of this lubricating oil for internal combustion engines is 46m 2 / s. In addition, the kinematic viscosity is measured in accordance with standard ASTM D445 under the temperature condition of 40 degreeC.

Abstract

Disclosed is a lubricant composition containing a lubricant base oil and at least one additive selected from the group consisting of organic metals and metal salts. By having such a constitution, the lubricant composition enables compressors, internal combustion engines or the like to reduce power or fuel consumption when used therein, while enhancing the cooling efficiency and suppressing decrease of output.

Description

technical field [0001] The present invention relates to lubricant compositions. Background technique [0002] Oil-containing lubricant compositions are used in compressors for compressing refrigerants such as Freon gas, internal combustion engines, and the like. In such compressors, internal combustion engines, and the like, the properties of the lubricant composition are changed to adjust the viscosity and compatibility with the refrigerant, thereby suppressing rotational torque. [0003] Such a lubricant composition is generally filled with a special lubricant composition suitable for the characteristics of the product in the product compressor, internal combustion engine, etc. at the time of shipment. In addition, commercially available general-purpose oil suitable for the product is often used for maintenance during use and when a unit is replaced due to failure. [0004] However, when a commercially available general-purpose oil is used, the general-purpose oil is mix...
