Embodiment 1

[0048] The additive of the present invention is configured by the following method: add 20 parts of F to the blending kettle G, stir and add 12 parts of B, 10 parts of C, 25 parts of D and 25 parts of E at room temperature and stir for 60 minutes, continue to stir and add 8 parts of A , and stirred for 20 minutes to obtain mixture 1. Among them, A selects diethyl ether; B selects a mixture of methyl oleate and methyl acetate with a weight ratio of 1:1, C selects vinyl unsaturated ester copolymer, D selects styrene-vinyl acetate, and E selects isooctyl nitrate , F selects xylene for use.

[0049] Add mixture 1 to -10# diesel oil in different dosages, use Foton Ollin CTX8 ton medium card to test the overnight starting protection temperature; adopt SH / T0694 standard, "Calculation method of middle distillate fuel cetane index (four variable formula method) )" to test the cetane number; adopt SH / T0765 standard "Diesel lubricity evaluation method (high frequency reciprocating testi...

Embodiment 2

[0054] Add 50 parts of F to the mixing tank G, stir and add 10 parts of B, 15 parts of C, 10 parts of D and 10 parts of E at room temperature and stir for 60 minutes, continue stirring and add 5 parts of A, stir for 20 minutes to obtain mixture 2. Among them, A uses dimethyl ether, B uses a mixture of methyl oleate, butyl oleate and methyl acetate with a weight ratio of 1:2:1, and C uses dodecyl fumarate-vinyl ethyl alcohol. Ester comb polymer, D selects polymethacrylate, E selects isopropyl nitrate, and F selects xylene.

[0055] Add 20 parts of F to the mixing tank G, stir and add 20 parts of B, 10 parts of C, 20 parts of D and 20 parts of E at room temperature and stir for 60 minutes, continue stirring and add 10 parts of A, stir for 20 minutes to obtain mixture 3. Among them, A is selected from diethyl ether, B component is selected from a mixture of methyl oleate, butyl oleate, isooctyl oleate and methyl acetate with a weight ratio of 1:1:1:1, and C component is selected ...

Abstract

The invention relates to a lubricating anti-wear diesel start protection additive, belonging to the field of diesel additives. The additive comprises the following components in percentage by weight: 5-10% of low-molecular ether A, 10-20% of combustion improver B, 5-15% of detergent C, 10-30% of pour point depressant D, 10-30% of cetane number improver E and 10-60% of solvent F. The additive produced by a conventional production process is added into diesel at a concentration proportion of 800-4,000ppm, and the cold filter plugging point of the diesel can be remarkably reduced while the fluidity, lubricating property, combustibility and start protection of the diesel can be improved.

Description

technical field [0001] The invention relates to an automotive diesel additive composition, in particular to a lubricating and anti-wear starting protection additive for diesel. Background technique [0002] Diesel additives can make up for the quality problems of diesel itself and the shortcomings of motor vehicle machinery manufacturing limits. For diesel engines, they can overcome the problems of finer atomization of fuel injectors and residual oil dripping, so as to remove carbon deposits and save fuel. , reduce emissions, enhance power and other effects. Divided by function, it includes emulsification energy-saving type, clean type, smoke reduction type, PM2.5 emission reduction, anti-rust type, stable type, etc. In order to achieve the optimum value of various properties of diesel additives, various researches have been carried out. [0003] For example, the patent CN102277212A relates to diesel performance-improving additives. It is a dual-effect additive mixture tha...
