Description

Technical Field

[0001] This invention belongs to the field of environmentally friendly fuel technology and relates to modified environmentally friendly fuel additives that can be applied to power equipment, such as internal combustion engines, specifically to an ignition-type environmentally friendly fuel additive. Background Technology

[0002] In recent years, facing the dual challenges of the oil energy crisis and environmental pollution, actively seeking and developing clean energy is one of the solutions. Currently, a new type of fuel has emerged, made by blending industrial methanol or fuel methanol with denatured alcohol additives in a specific volume (or weight ratio) with existing gasoline (or component oils). This fuel can partially or completely replace gasoline or diesel internal combustion engines, and even the fuel required for boiler combustion.

[0003] Methanol was chosen because it is readily available, inexpensive, and can be produced in large quantities. It also possesses moderate to low toxicity, similar to gasoline, making it a potential fuel for ultra-clean combustion and high-clean emissions. In particular, methanol is the simplest compound in terms of structure among alcohols, with its polar hydroxyl group occupying the highest proportion in its molecular structure. It has an oxygen content as high as 50%, an auto-ignition point of 460℃, a latent heat of vaporization of 1100 MJ / kg, a calorific value of 4,650 kcal / kg, and an air-fuel ratio of 6.45. Although its air-fuel mixture has a slightly lower calorific value than gasoline, it features rapid combustion, quick heat release, and high thermal efficiency.

[0004] Authorization announcement number CN101486940B discloses a methanol fuel additive for diesel engines, composed of the following components in the following volume ratios: 35-45% isooctyl nitrate; 10-20% ethylene glycol dinitrate and / or glycerol trinitrate; 25-40% ethylene glycol methyl ether and / or ethylene glycol ethyl ether and / or ethylene glycol butyl ether; and 5-10% fatty alcohol compounds. The methanol fuel for diesel engines containing the above methanol fuel additive has a methanol volume content of 93-97% and an additive volume content of 3-7%. This improves the power performance and ignition performance of the methanol fuel, increases its cetane number, eliminates the potential corrosion effect of methanol on engine system components, and saves petroleum resources and reduces environmental pollution.

[0005] Authorization announcement number CN102634383B discloses a methanol fuel additive and the methanol gasoline prepared therefrom. The additive comprises the following components by weight ratio: 15.9-20 parts modifier, 8-12 parts oxidizer, 12-8 parts activator, 15-17 parts antiknock agent, 0.54-2.48 parts detergent, 40.5-34.5 parts catalyst, 8-6 parts corrosion inhibitor, and 0.06-0.02 parts friction-reducing lubricant. The modifier is a mixture of di-tert-butyl peroxide, benzene, propanol, and xylene; the oxidizer is methyl tert-butyl ether; the activator is naphtha; the antiknock agent is a mixture of hydroquinone and isopropanol; the detergent is a mixture of dicyclopentadiene and propanol; the catalyst is a mixture of solvent oil, acetone, and diisopropylamine, or a mixture of solvent oil, acetylacetone, and diisopropylamine; the corrosion inhibitor is methylbenzotriazole; and the friction-reducing lubricant is a mixture of potassium permanganate and potassium chloride. This additive allows methanol and gasoline to be miscible, and the resulting methanol gasoline burns completely, has high power, and good anti-knock properties.

[0006] Authorization announcement number CN103627454B discloses a methanol fuel for spark-ignition engines, characterized by the following volume percentage of raw materials: methanol 5%–85%; additives 0.05%–0.8%; the remainder being gasoline or gasoline component oil; the additive being n-octylamine; the gasoline component oil being light hydrocarbons with a composition of C5–C12; and the gasoline component oil being alkanes with a composition of C5–C12. This solves the problems of complex additive composition in existing methanol fuels leading to corrosiveness to metals and swelling of rubber, while also addressing the issues of high dosage and cost associated with methanol gasoline additives.

[0007] Authorization announcement number CN106520230B discloses a methanol fuel composite additive that facilitates cold starting of compression ignition engines. It comprises the following components by mass percentage: 34-45% co-solvent, 0.5-1% antioxidant, 0.5-1% metal corrosion inhibitor, and the balance being the main agent. The main agent is a mixture of acetone, methyl acetate, cyclopentane, ethylene glycol diethyl ether, 1,1-dimethoxyethane, bromoethane, and 2-methyl-2-butene. The co-solvent is a mixture of isobutanol, isoamyl alcohol, octanol, and tert-butyl acetate. The antioxidant is a mixture of 2,6-di-tert-butylphenols. The metal corrosion inhibitor is N,N'-disalinepropylenediamine. This additive alters the low-temperature volatility of methanol, increases the degree of vaporization and evaporation rate during methanol combustion, improves the low-temperature fluidity of methanol, and mitigates the impact of the cooling effect caused by the high latent heat of vaporization of methanol on engine performance, enabling the engine to start smoothly at -40°C.

[0193] Furthermore, the sum of the volume percentage concentrations of the various agents can be appropriately adjusted to make its proportion 15.0 vol%, while the volume percentage concentration of the environmentally friendly fuel is 85.0 vol%.

[0194] Furthermore, regarding the preparation of the additives disclosed in this embodiment, each agent and each sub-agent needs to be prepared separately as a pre-use stock, and then the agents are mixed separately, and the components are thoroughly and evenly mixed by stirring. In other words, after the main heat-enhancing agent, the catalyst sub-agent, the preservative emulsifying agent, the scorching-resistant agent, the combustion-supporting agent, the calorific value increasing agent, and the calorific value promoting agent are prepared separately, the sub-agents are then mixed to form the high-efficiency energy-enhancing agent.

[0195] Similarly, the power enhancer is also prepared by first preparing the solvent agent, the igniter agent, and the nitro combustion enhancer agent, and then mixing the three agents together.

[0196] Pre-mixing into a pre-prepared sample allows the components of the same dosage form a uniform mixture beforehand. This prevents immiscibility or stratification between components of different dosages when mixing them.

[0197] The above is a description of preferred embodiments of the present invention. All figures used in this specification and claims, including expressions of content, proportions, and physical characteristics, should be understood to be modified by the term "about" in all cases. Therefore, unless otherwise indicated, the numerical values ​​set forth in the following specification and claims may vary depending on the characteristics sought to be obtained and / or desired by the present invention. At least, and without attempting to limit the application of the equivalence principle to the scope of the claims, each numerical parameter should be interpreted at least according to the number of significant digits disclosed and by applying general rounding techniques. Therefore, any implementation by equivalent skill or within the scope of the claims does not depart from the scope of the present invention and is within the applicant's rights.
