Improved multi-functional fuel oil additive

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

technical field [0001] The present invention relates to an improved multifunctional fuel additive. Background technique [0002] Although automobile technology has made great progress, the design of automobile engine improves the combustion system as much as possible to improve the combustion efficiency of fuel, but the general aspect still fails to completely solve the incomplete combustion of fuel in the engine, resulting in deposits and harmful gas phenomenon. Because when the engine is running, the temperature of the fuel injector is around 100°C, and the temperature of the intake valve is between 200-300°C. At such a temperature, the unstable components in the fuel are prone to oxidative condensation reactions, forming colloids and carbon deposits, which are deposited on the intake valves and fuel injection nozzles. Advanced high-pressure engines and GDI fuel direct injection Technical engines are more prone to carbon deposits. The deposits accumulated on the intake ...

AI Technical Summary

Problems solved by technology

The deposits accumulated on the intake valve will reduce the cross-sectional area of ​​the intake passage, reduce the intake efficiency, and reduce the power. In severe cases, the valve will move slowly and close tightly.

Carbon deposits in the fuel injector will lead to poor fuel injection and poor fuel atomization quality, which will make it difficult to completely burn the fuel after it enters the combustion chamber, resulting in difficulty in starting the engine, unstable idling speed, increased fuel consumption, and worsened exhaust emissions, especially in In winter, these conditions are more pronounced
