Technical Field

[0001] This invention belongs to the field of gasoline additive technology, and particularly relates to an energy-saving and pollution-reducing gasoline cleaning and enhancing agent and its preparation method. Background Technology

[0002] Currently, mobile sources have become a significant source of air pollution emissions. To address mobile source pollution, gasoline additives have been widely used. However, existing gasoline additive technologies face the following main problems in practical application:

[0003] (1) Some additives only act as detergents, that is, to inhibit and remove carbon deposits and deposits, but cannot improve the situation of vehicles emitting a large amount of gaseous pollutants.

[0004] (2) Some additives illegally use illegal additive components, such as MMT containing manganese metal antiknock agent, which will damage the vehicle's fuel system, shorten the service life of engine parts, and increase maintenance costs after use;

[0005] (3) Some additives are exaggerated in their advertising and do not actually have the effects of reducing emissions, saving fuel and improving power, because the above three performance indicators have not been scientifically tested and verified. Summary of the Invention

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] The technical principle of this invention is to use amine compounds and ether compounds prepared with a special formula, free of metal components and ash, as the main components. Their molecular structure is mainly composed of multiple functional groups. Under the high pressure and high temperature conditions of an engine, a large number of free radicals are generated during fuel combustion, triggering a chain reaction of molecular chains, optimizing the combustion process, and effectively improving fuel economy, power, and pollutant control. The core technology achieves different optimization effects through different functional groups, effectively increasing the heat of combustion per unit volume, thereby improving combustion efficiency while reducing fuel consumption and emissions of HC, CO, and NO. X Pollutant emissions.

[0038] This invention is completely different from gasoline detergent technology. The former mainly improves gasoline quality and optimizes the combustion process by co-burning with gasoline, making it more compatible with the engine's working process, ensuring stable and efficient engine operation, and achieving the purpose of reducing pollution and fuel consumption; the latter mainly inhibits the formation of deposits in engine intake valves, intake manifolds, and fuel injectors and removes existing deposits.

[0039] This invention relates to an energy-saving and pollution-reducing gasoline cleaning and enhancement agent that improves gasoline combustion efficiency and reduces gasoline vehicle emissions. Through scientific screening and rational optimization, the proportions of each component in this invention were ultimately determined. The main purpose is to improve the gasoline combustion process, increase gasoline combustion efficiency (improving fuel economy), and achieve fuel savings of 1.5%-3.1%. Simultaneously, it reduces the levels of three gaseous pollutants from gasoline vehicles: CO, HC, and NO. X Emissions, CO+HC+NO X The overall emission improvement rate is over 20%, reaching up to 23%, with no increase in emissions of any individual gaseous pollutants; it reduces in-cylinder friction loss, improves vehicle power performance, and increases torque by 1.2%-1.6%; it has significant practical value. It solves the problems of existing technologies being unable to simultaneously reduce the above three gaseous pollutants and having unstable effects; the product of this invention is neutral and will not cause any acid or alkali corrosion to the engine, thus maintaining the engine and extending its service life, solving the toxicity and corrosiveness problems of existing technologies.

[0040] Specifically, the present invention has the following characteristics:

[0041] 1. This product is green and environmentally friendly, free of heavy metals and harmful components such as phosphorus and chlorine, and has excellent miscibility with gasoline.

[0042] 2. Dimethyl carbonate in the components can increase the octane number and oxygen content of gasoline (up to 34.8%), thereby improving the anti-knock performance and combustion performance of gasoline, and has the characteristics of low toxicity and excellent environmental performance.

[0043] 3. Polyetheramine: The hydrophilicity of the polyether segments disperses calcium and magnesium salt particles, and the amine groups adsorb onto the particle surface to prevent aggregation, thus effectively preventing and reducing the formation of engine deposits and carbon buildup.

[0044] 4. Surfactants reduce the intermolecular forces of oil molecules by adsorbing onto the surface or interface of a liquid, making the liquid easier to spread or mix, and promoting the evaporation and mixing of fuel.

[0045] 5. C9-C11 mixed olefins have advantages such as a wide liquid range, low pour point, and high viscosity index. Appropriate addition can improve the octane number of gasoline and have good anti-knock properties.

[0046] 6. N,N-di-sec-butyl has a highly efficient antioxidant and anti-gumming effect, which can effectively prevent the oxidation of olefins to produce gum or carbon deposits, thereby avoiding the generation of carbon deposits in the combustion chamber, piston top, cylinder head and other parts during gasoline combustion.

[0047] 7. Trimethylolpropane can decompose at high temperatures to produce highly reactive free radicals, which can increase the flame propagation speed, thus promoting combustion and suppressing detonation. Detailed Implementation
