Abstract

The invention provides a boat plunger-type engine lubricating oil composition. The boat plunger-type engine lubricating oil composition comprises, by mass, 1-15% of an alkyl sulfonate clearing agent, 1-15% of an alkyl salicylate clearing agent, 0.1-5% of synthetic polyether, 0.1-5% of a dispersant, 0.1-5% of an antiwear agent and the balance II-type base oil. The boat plunger-type engine lubricating oil composition has good antirust and antioxidation performances, utilizes alkyl salicylate structure particularity, can well be dissolved in an underburned part of heavy fuel and can effectively inhibit black oily sludge produced from the underburned part of the heavy fuel. Through use of the synthetic polyether, the boat plunger-type engine lubricating oil composition can be used in the II-type base oil so that good lubrication performances are obtained and boat plunger-type engine lubricating requirements are satisfied.

Description

technical field [0001] The invention relates to an engine lubricating oil composition, in particular to a marine plunger engine lubricating oil composition. Background technique [0002] Marine engines can be divided into two strokes and four strokes according to the stroke. Among them, the four-stroke engine is often a plunger engine, and the lubricating oil used is medium-speed engine oil. With the development of engine technology, new engines with higher explosion pressure and longer stroke have put forward new requirements for lubrication. In recent years, along with the development of engine technology, some new technologies have appeared in corresponding lubricating oils to match it. For example, the appearance of salicylate detergent to solve the carbon deposition technology of engine pistons is, to a large extent, a guarantee for new engines. Lubrication provides a better solution. [0003] Marine medium-speed engines generally use heavy fuel, so they contain a ce...
