Abstract

The invention provides lubricating oil for a dimethyl ether engine. The lubricating oil contains neutral base oil, screen phenol, branched alkylphenol and branched calcium alkyl phenate, calcium long-chain alkaryl sulphonate, sulfurized calcium alkyl phenolate, polyisobutylene succinimide ashless dispersant, zinc dialkyl dithiophosphate, a viscosity index improver and a pour point reducer. The dimethyl ether engine lubricating oil can meet the lubricating requirement of the dimethyl ether engine.

Description

technical field [0001] The invention provides a lubricating oil, in particular a dimethyl ether engine lubricating oil. Background technique [0002] DME fuel can achieve full combustion, significantly reduce engine noise, NOx and particulate emissions, and can improve my country's energy structure. In recent years, DME engines have attracted people's attention. With the increasingly strict control of automobile emissions by environmental protection regulations, environmentally friendly and clean DME engines are bound to be widely used, so DME engine oils have broad market prospects. And the technology that relates to dimethyl ether engine oil has not yet found open documents. Contents of the invention [0003] The main purpose of the present invention is to provide an internal combustion engine lubricating oil that can meet the working requirements of the DME engine according to the characteristics of the DME engine. [0004] The purpose of the present invention and the...
