  The present invention relates to a cylinder lubricating oil for crosshead diesel engines. In addition to having conventional characteristics such as heat resistance, cleanliness, wear resistance, and the like, the cylinder lubricating oil can be used with fuel of any sulfur content and suppresses the amount of piston deposit even when the base number is excessive. In greater detail, the present invention relates to a cylinder lubricating oil composition which includes an ashless dispersant (B) and a metallic detergent (C) in a lubricant base oil (A), in which the product of the number average molecular weight, the content, and the effective concentration of the ashless dispersant (B) is at least 9000, and the endothermic peak temperature of the metallic detergent (C) as measured by DSC at a rate of temperature increase of 50°C/min is at most 460°C.

  本发明涉及一种用于十字头柴油发动机的气缸润滑油。除了具有耐热性、清洁性、耐磨性等常规特性外，该气缸润滑油还可与任何硫含量的燃料一起使用，并且即使在基数过高的情况下也能抑制活塞沉积物的数量。更详细地说，本发明涉及一种气缸润滑油组合物，该组合物包括润滑油基础油（A）中的无灰分散剂（B）和金属清净剂（C），其中无灰分散剂（B）的平均分子量、含量和有效浓度的乘积至少为 9000，并且在升温速度为 50°C/min 时，通过 DSC 测得的金属清净剂（C）的内热峰温度最高为 460°C。
