Description

Technical Field

[0001] This invention belongs to the field of clean fuel technology, specifically an environmentally friendly and energy-saving clean fuel for diesel engines. Background Technology

[0002] With rapid economic development, the demand for fuel is constantly increasing. Diesel is an indispensable fuel for both domestic and industrial use, and its quality directly affects not only the performance of diesel engines but also the environment. However, current diesel fuel contains many impurities and is of poor quality. Poor combustion of diesel fuel leads to reduced engine power and insufficient performance. Furthermore, diesel combustion more easily produces carcinogenic soot. Nitrogen oxides and particulate matter in vehicle exhaust are major sources of PM2.5 pollutants, causing air pollution and failing to meet environmental protection standards. On the other hand, prolonged use of low-quality diesel fuel accelerates the wear and tear on fuel system components, reducing the lifespan of diesel engines. Additionally, the high price of diesel fuel limits its wider use in industrial and consumer sectors.

[0003] In existing technologies, alcohol-based fuels are commonly used as alternatives to diesel fuels. These fuels are primarily composed of alcohols, such as methanol and ethanol. However, alcohol-based fuels have relatively low calorific value and are difficult to synthesize; synthesizing fuels comparable to gasoline and diesel is even more challenging. Furthermore, alcohol-based fuels can cause problems in practical applications, such as flameout, high-temperature vapor lock, and corrosion of fuel tanks and pipelines, limiting their application. Therefore, developing a clean, environmentally friendly diesel engine fuel with high fuel efficiency is a crucial technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides an environmentally friendly and energy-saving clean fuel for diesel engines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides an environmentally friendly and energy-saving clean fuel for diesel engines, which is prepared by additives and kerosene in a mass ratio of 1:(300-430).

[0007] Furthermore, the additive comprises the following raw materials in parts by weight: 40-62 parts of cetane number improver, 5-10 parts of anti-knock agent, 15-30 parts of corrosion inhibitor, 8-10 parts of dimethyl silicone oil, and 3-6 parts of detergent.

[0008] Furthermore, the additive comprises the following raw materials in parts by weight: 42-50 parts of cetane number improver, 5-9 parts of anti-knock agent, 20-25 parts of corrosion inhibitor, 9 parts of dimethyl silicone oil, and 6 parts of detergent.

[0009] Preferably, the additive comprises the following raw materials in parts by weight: 45 parts of cetane number improver, 8 parts of anti-knock agent, 23 parts of corrosion inhibitor, 9 parts of dimethyl silicone oil, and 6 parts of detergent.

[0010] Furthermore, the cetane number improver is a mixture of isooctyl nitrate and dimethoxypropane in a mass ratio of 1:(2-4).

[0011] Beneficial effects: This invention uses a mixture of isooctyl nitrate and dimethoxypropane as a cetane number improver. The two work synergistically to further improve the cetane number of the fuel, thereby making the fuel combustion easier to start and also helping to improve the uniformity of fuel combustion. The two complement each other and are indispensable.

[0012] Furthermore, the anti-knock agent is a mixture of epoxidized soybean oil methyl ester and methyl tert-butyl ether in a mass ratio of 1:1.

[0013] Beneficial effects: This invention uses a mixture of epoxidized soybean oil methyl ester and methyl tert-butyl ether as an antiknock agent, which effectively increases the antiknock properties of diesel engine fuel, and has the characteristics of low price and green environmental protection.

[0014] Furthermore, the corrosion inhibitor is a mixture of trimethylbenzene and triacetin in a mass ratio of (1-2):1.

[0015] Furthermore, the cleaning agent is N,N-disaline propylene glycol or polyisobutylene.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention mixes additives with kerosene, further improving fuel stability and utilization. This allows the prepared clean fuel to burn effectively during use, reducing environmental pollutants generated during combustion and fundamentally solving the problems of environmental pollution and resource shortage. It can be widely applied in the field of clean fuel technology. Detailed Implementation
