Problems solved by technology

[0004] In today's gasoline additive technology, the research on gasoline additives focuses on the level and direction of additives with a single function or less composite functions. It is difficult for composite additives to achieve multifunctional effects, and some additive formulations use gasoline additives. or car harmful substances
Such as the cerium naphthenate in the vehicle fuel oil composite modification performance additive formula of Chinese patent CN1896198A, the ferrocene in the gasoline fuel-saving purifying agent formula of Chinese patent CN1445431A all are organometallic compounds, and it can aggravate the wearing and tearing of automobile engine, simultaneously Dichloroethane in the gasoline fuel-saving purifying agent formula of CN1445431A is also a harmful component to gasoline, which can cause noble metal three-way catalyst poisoning, which will have adverse effects on gasoline or automobiles

Abstract

The invention provides a multifunctional gasoline compound additive which is capable of reducing fuel consumption and decreasing the pollution caused by tail gas emission. The additive comprises a gasoline cleaning agent, a combustion improver, a low temperature start improving agent, an antiknock agent, an anti-oxidizing and anti-gum agent and a metal corrosion inhibitor. By adopting the gasoline compound additive, the cleanness, oxidation resistance and anti-corrosion performance of gasoline can be improved; and meanwhile, the combustion performance of fuel oil can be improved, the fuel consumption is reduced, and the automobile tail gas pollutants can be reduced.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a gasoline multifunctional composite additive capable of reducing fuel consumption and tail gas emission pollution. Background technique [0002] Under the background of depleting oil resources and declining global oil reserves, my country's demand for fuel is increasing day by day, and the utilization rate of my country's petroleum products, especially motor vehicle fuel, is generally low, which not only causes waste of fuel, but also It also leads to a problem of increased air pollution due to the generation of motor vehicle exhaust pollutants. [0003] Gasoline in my country mainly has high olefin content. When a large amount of olefins are burned in the engine, a large amount of deposits will be generated on the engine injector and intake valve, which will reduce the fuel injection efficiency and further reduce fuel utilization. Polymerization of gums will result in incre...
