Additive for improving engine power

Abstract

The invention provides an additive for improving engine power, which comprises, by weight, 5-15 parts of a compound friction modifier, 5-10 parts of a dispersant, 1-8 parts of a viscosity regulator, 5-15 parts of an antioxidant, 2-20 parts of a surfactant and 0-30 parts of others. The additive can effectively play the role of wear resistance and abrasion resistance, and can also improve the enginepower and the combustion efficiency of fuel oil.

Description

technical field [0001] The invention relates to the technical field of gasoline additives, in particular to an additive capable of improving engine power while exerting friction and lubricating effects. Background technique [0002] 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, and are also an important topic and direction of additive research and development. The use of additives with anti-wear and anti-friction effects can effectively improve engine performance. Safety, stability, durability and thermal stability and other properties. [0003] The key to improving friction is to improve the lubrication between friction surfaces or contact points. The friction modifier used in additives is the main substance to adjust lubrication. They usually play a role in two ways: one is through the adsorption and deposition of surface groups The other is to fo...

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.

[0004] 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

[0005] 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
