Problems solved by technology

Due to the low proportion of Group V base oil and excessive use of viscosity index improvers, there are great limitations in performance, including noise control, power improvement, emission reduction, fuel consumption reduction, and mileage increase.
The technical bottleneck lies in: the hydrolysis problem of Group V oils, which leads to the inability to increase the ratio of Group V oils; the viscosity-temperature performance of traditional high-viscosity base oils with high viscosity IV cannot meet the SAE requirements, resulting in the inability to reduce the usage of viscosity index improvers

Abstract

The invention belongs to the field of lubricating oils, particularly relates to a fully synthetic ester-based gasoline-injection engine lubricating oil. The lubricating oil is prepared from the following raw materials: PAO4, PAO6, PAO8, metallocene PAO (Poly Alpha Olefins), diester A41, diester A51, polyalcohol ester NP451, polyalcohol ester NP343, alkyl naphthalene, a compound gasoline-injection engine oil additive, a hydrolysis inhibitor and an antioxidant enhancement package, wherein the proportion of the V-type ester-based base oil exceeds 30%, so that the lubricating oil is strong in anti-shearing capacity, namely, the lubricating oil is a fully synthetic high-performance ester-based lubricating oil which can be safely used for a long period. The invention further provides a preparation process of the fully synthetic ester-based gasoline-injection engine lubricating oil. The preparation process is reasonable. Thus, the evaporation loss of a finished product of the lubricating oil is minimized; and the high-temperature of the lubricating oil is performed before the lubricating oil is injected into an engine, so that the synergistic effects of all components of the lubricating oil are exerted well.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and in particular relates to an ester-based fully synthetic gasoline internal combustion engine lubricating oil and a preparation process thereof. Background technique [0002] Gasoline internal combustion engine lubricating oil, referred to as steam engine oil, is used in gasoline-fueled engines to perform functions such as lubrication, sealing, heat dissipation, and cleaning. Engine oil consists of two components: base oil and additives. Base oil grades are divided into five categories: Ⅰ, Ⅱ, and Ⅲ are mineral oils, which are produced by traditional petroleum refining processes; Ⅳ, Ⅴ are synthetic oils, which are produced by chemical synthesis processes; Poly-alpha-olefin (PAO) and polyester, etc., and category V are esters, alkylnaphthalene, and polyether. According to the performance level, Class V > Class IV > Class III > Class II > Class I. The additives are compounded from met...
