Problems solved by technology

[0006] (1) Due to the poor lubricating performance of dimethyl ether, the plunger coupling and valve assembly of the high-pressure oil pump in the engine fuel supply system suffer from severe friction and wear
[0007] (2) The acidic substances produced by the combustion of dimethyl ether fuel are highly corrosive to engine parts and easily cause rust and wear
[0008] (3) Acidic substances produced by combustion cause corrosion and wear to pistons and cylinders
[0009] At present, the lubricating pe...

Abstract

The invention discloses a vehicle dimethyl ether abrasion resistant lubricant which comprises the compositions as follows: antiwear additive, pour point depressant and solvent; wherein, the antiwear additive is selected more than one of the followings: oleic acid, butyl stearate or triolein ; the pour point depressant is selected from the copolymer of ethylene-vinyl acetate; the solvent is de-aromatic hydrocarbon solvent kerosene; the vehicle dimethyl ether abrasion resistant lubricant is applicable to the car engine which uses dimethyl ether as the vehicle fuel and power; the vehicle dimethyl ether abrasion resistant lubricant has the advantages of good lubrication performance, good abrasion resistance, proper polarity, good anticorrosion performance, good environmental-friendly discharge performance, guaranteeing the predetermined concentration for long time, maintaining stable state, good dispersion property in the dimethyl ether (even mixing), being harmless to humans and fulfilling the application requirement of the gas fuel engine; furthermore, the vehicle dimethyl ether abrasion resistant lubricant has the advantages of small addition dosage and low cost.

Description

technical field [0001] The invention relates to a lubricant, in particular to an anti-wear lubricant specially used for dimethyl ether vehicle fuel. Background technique [0002] The rapid development of the economy and the rapid growth of the number of automobiles will face the dual pressure of automobile energy demand and atmospheric environmental protection. The development and application of new alternative fuels for vehicles has become a hot spot for clean vehicle fuels in the new century. Dimethyl ether (DME) vehicle fuel is a new vehicle fuel developed in recent years. It has the advantages of high calorific value, complete combustion, reduced pollution and clean air. [0003] Since dimethyl ether is an ether compound with strong polarity and no lubricating effect, it also has a certain cleaning effect on lubricants. If it is used directly, it will accelerate the wear of the high-pressure fuel pump and valve system of the car, and the oil supply will be damaged in a ...
