Abstract

The invention relates to an improved multi-functional fuel oil additive. The improved multi-functional fuel oil additive is prepared from the following raw materials in parts by weight: 5-9 parts of lauroyl diethanolamide, 3-6 parts of carboxylic ester, 5-7 parts of polyether acetate, 4-8 parts of non-ionic surface active agent, 6-8 parts of petroleum solvent, 6-10 parts of glycerol monostearate, 3-9 parts of petroleum calcium sulfonate, 1-5 parts of ethyl tert butyl ether, 1-4 parts of combustion improver, 4-9 parts of boronized succinimide, 2-7 parts of cupric isooctoxylborate, 3-8 parts of polyisobutene carbamate, 5-8 parts of dibutyl phosphite and 1-3 parts of viscosity index improver. The improved multi-functional fuel oil additive can improve the low temperature resistance of fuel oil, has corrosion-resistant and lubricating functions and can protect the engine.

Description

A kind of multi-functional fuel oil additive of improvement

Technical field

The present invention relates to a kind of multi-functional fuel oil additive of improvement.

Background technology

Although automotive engineering makes great progress, Automobile Motor Design as much as possible improves firing system, to improve the efficiency of combustion of fuel, but total aspect still thoroughly could not solve fuel incomplete combustion within the engine, produces the phenomenon of settling and obnoxious flavour.Because during running of an engine, oil nozzle temperature is at about 100 DEG C, and intake valve temperature is between 200-300 DEG C.At such temperatures, the labile element in fuel oil, very easily produces oxidative dimerization, generates colloid and carbon distribution, is deposited on intake valve and oil nozzle, and the engine of advanced highly turbocharged engine and use GDI fuel direct injection technology more easily produces carbon distribution.Be deposited in the settling on intake valve, induction trunk sectional area can be caused to reduce, intake efficiency reduces, and power drop, can make valve event slow, be not closed completely time serious.Oil nozzle carbon distribution, oil spout can be made not smooth, and fuel spray Quality Down, after causing fuel oil to enter combustion chamber, is difficult to perfect combustion, and cause engine starting difficulty, unstable idle speed, and oil consumption strengthens, exhaust emissions worsens, and especially in winter, these situations are more obvious., therefore need fuel oil additive, improve the utilization ratio of fuel oil, engine is protected simultaneously.

Summary of the invention

For the deficiencies in the prior art, the technical problem to be solved in the present invention is, provides a kind of multi-functional fuel oil additive of improvement, can improve the resistance to low temperature of fuel oil, has effect that is anticorrosion, lubrication, protection engine simultaneously.

For solving the deficiencies in the prior art, the technical scheme that the present invention takes is: a kind of multi-functional fuel oil additive of improvement, is made up of the raw material of following parts by weight:

Lauric acid diethyl amide 5-9 part, carboxylicesters 3-6 part, polyethers acetic acid 5-7 part, nonionogenic tenside 4-8 part, petroleum solvent 6-8 part, glyceryl monostearate 6-10 part, calcium mahogany sulfonate 3-9 part, Ethyl Tertisry Butyl Ether 1-5 part, combustion improver 1-4 part, boronation succimide 4-9 part, Cupric isooctoxylbordte 2-7 part, polyisobutene carbamate 3-8 part, di-n-butyl phosphite 5-8 part, viscosity index improver 1-3 part.

The invention has the beneficial effects as follows that the multi-functional fuel oil additive of improvement of the present invention can improve the resistance to low temperature of fuel oil, there is effect that is anticorrosion, lubrication, protection engine simultaneously.
