Problems solved by technology

In addition, because phosphorus-containing catalysts will enter the catalytic converter through exhaust gas recirculation or blow-by process, and accumulate on the active metal site, poisoning the catalyst, thereby reducing the catalyst's efficiency and shortening its service life, so phosphorus-containing additives are used as lubricating oil components subject to specification standards

Abstract

The invention discloses a gasoline engine lubricating coil composition and a preparation method thereof. The gasoline engine lubricating coil composition comprises the following components in percentby weight: (A) 0.1 to 6.0 percent of an ashless dispersing agent, (B) 0.1 to 8.0 percent of a clearing agent, (C) 0.01 to 1.5 percent of oil-soluble or dispersible oil stability boron-containing compound, (D) 0.003 to 0.5 percent of oil-soluble or dispersible oil stability molybdenum-containing compound, (E) 0.02 to 3.2 percent of zinc dialkyl dithiophosphate, (F) 0.01 to 3.0 percent of an antioxidant and (G) lubricating oil base oil with a main amount, wherein the boron molybdenum mass ratio of the component (C) to the component (D) ranges from 1:5 to 10:1. The blended gasoline engine oil composition contains all of the boron-containing compound, the molybdenum-containing compound and the zinc dialkyl dithiophosphate, completely exerts the synergistic effect between the additives, improves the anti-oxidation property, the anti-wear and friction-reducing properties and the extreme pressure property of the lubricating oil composition and reduces the ash content and the thionazin contentof the lubricating oil composition.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular to a lubricating oil composition, in particular to a lubricating oil composition for a gasoline engine. Background technique [0002] In recent years, with the increasingly serious environmental pollution, especially the frequent occurrence of some extreme weather and the ubiquity of smog, people have paid great attention to it. The emission of automobile exhaust is one of the main causes of smog weather. Therefore, with the increasingly stringent emission regulations, the requirements for engine emissions are becoming more and more stringent, which puts forward higher requirements for the performance of engine lubricating oil. . [0003] At present, the specifications of high-end gasoline engine lubricating oil products have been upgraded to the SM / GF-4 and SN / GF-5 grades formulated by the International Lubricant Standardization and Certification Committee (ILSAC) and the American...
