A gasoline that boosts engine power

Abstract

The invention provides a gasoline for improving engine power, comprising 180-550 parts of base gasoline, 5-15 parts of a compounded friction modifier, 8-12 parts of a dispersant, 12-18 parts of a viscosity modifier, and 3-6 parts of an antioxidant 1-15 parts of surfactants, 5-18 parts of detergents, and 0-10 parts of others; the compound friction modifier is composed of nitrogen-containing borated ether antiwear agent, nitrogen-containing hindered phenolic anti-wear agent agent, and stearic acid surface-modified kaolin compound; the dispersant is succinimide whose imino hydrogen is replaced by alkoxy, acyloxy or hydroxyl, and dimethyl carbonate and isopropanol compound; the viscosity modifier is a hydrogenated-styrene-diene polymer; the antioxidant is a naphthylamine compound; the surfactant is a low-molecular linear alcohol ether; the detergent is a hydroxyl-containing Polyetheramine. The invention can improve lubrication, improve engine power, improve fuel economy and reduce carbon deposition.

Description

technical field [0001] The invention relates to the technical field of gasoline and its additives, in particular to a gasoline capable of improving engine power while improving lubrication and reducing carbon deposits. Background technique [0002] It is well known that adding certain additives to gasoline can improve various performances of gasoline. There are many types of additives in gasoline today, but most of them only focus on improving one or two properties, and have no advantage in the balance of improving multiple properties. For example, anti-wear additives often aggravate the carbon deposition problem, and although the addition of metal detergents reduces carbon deposition, it has an adverse effect on engine power. These problems are more pronounced in high-octane gasoline grades. [0003] More than 90% of the problems in automobile engines come from wear. Additives that improve friction and wear hazards are one of the important functions of engine additives, a...

Problems solved by technology

These two pathways may work alone or in concert. At the same time, the effects of these adsorption, deposition, reaction, and penetration are also affected by many complex factors, such as metal surface conditions, viscosity, temperature, rotational speed, impurities, concentration, etc. etc. Therefore, there are various problems in the practical application of additive lubrication and anti-friction effects, and there are also large differences.

[0005] In recent years, with the improvement of engine performance requirements, the types of additives containing friction modifiers are also developing towards diversification. According to the elemental composition of friction modifiers, they can be roughly divided into the following categories: first, sulfur and phosphorus compounds, This type of compound is widely used due to its good extreme pressure and anti-wear effect, but with the improvement of environmental protection requirements, the development of sulfur- and phosphorus-free additives has become an inevitable trend; the second is organic molybdenum, copper and other sulfur-phosphorus organic compounds This kind of compound is widely used in gasoline with environmental protection requirements because of its good anti-oxidation performance at the same time. However, because it contains metal elements that are easy to deposit, it is easy to form carbon deposits or deposits in the engine, which is harmful to the cleaning of the engine. Unfavorable; the third is inorganic nanoparticles, such as nano-cerium dioxide and silicon dioxide, which are also easy to deposit inside the engine and cause cleaning difficulties, and the amount of addition is limited, which has the problem of poor compatibility with base oil; there are also some Natural environmental protection compounds such as tartaric acid, citric acid, and malic acid, etc. or their esterified modified compounds, but these compounds have poor high temperature performance and have not been widely used in additives

[0006] No matter what kind of friction modifier is used, the formation of good frictional lubrication will bring about a certain viscosity change, and this viscosity change will have an adverse effect on engine power improvement, fuel economy and efficiency will be restricted, such as the commonly used two Zinc dithiophosphates (ZDDP) are believed to have a detrimental effect on the overall economic efficiency of the fuel
