Problems solved by technology

[0005] The method of using diesel oil additives in the prior art can improve the low-temperature fluidity of diesel oil, promote the combustion of diesel oil or improve the anti-explosion property of diesel oil to a certain extent, but the function is single and can only improve a certain performance of diesel oil. One performance will reduce other performances and indicators at the same time, lack of synergy between components

Abstract

The invention relates to additives for engine fuel, in particular to a multifunctional bio-diesel composite additive for vehicles, which is characterized by selecting an appropriate cetane number improver, a clean agent, a dispersing agent and a shielding phenol type antioxidant. The additive comprises ethylene glycol dinitrate, 2-methyl cellosolve, 2-ethyl hexanol, diphenylamine, ethylene glycol alkyl benzene ether, succinimide, shielding phenol type antioxidants, hexadecyl dimethyl ammonium chloride and polyethyleneglycol hexadecyl phenolic ether. The additive adopting the components greatly improves operating performance of diesel and driving performance and acceleration performance of automobiles, keeps a fuel system to have good operating conditions, can reduce emission amount of harmful substances in tail gas, and has remarkable fuel-saving effect.

Description

technical field [0001] The invention relates to an additive for engine fuel, in particular to a composite biodiesel additive for a multifunctional vehicle. Background technique [0002] my country is an oil-importing country with limited oil reserves. Importing a large amount of oil poses a threat to my country's energy security. Therefore, improving the quality of oil products is more practical for China. Biodiesel has three major advantages: renewable, clean and safe. Experts believe that biodiesel is of great strategic significance to the adjustment of my country's agricultural structure, energy security and comprehensive management of the ecological environment. At present, automobile dieselization has become a development direction of the automobile industry. [0003] Biodiesel can not only alleviate human dependence on petroleum, but also a renewable energy source. It is based on these characteristics that at present, biomass diesel is forming a rapidly developing g...
