Description

201219555 VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to an additive and method for improving the combustion efficiency of a simmering juice, in particular, an additive and method for increasing the current rate of liquid fuel smoldering. [Prior Art] K. The global energy crisis and environmental pollution are becoming more and more serious. In addition to seeking alternative energy, the solution is more urgent to seek improved combustion efficiency and reduce the use of fuel.

, Lili's method. The existing methods for improving combustion efficiency are quite diverse, and in addition to the mechanical structure of the device, the use of various fuel additives is also known to the public. For example, adding 4~1〇 wt% methyl tert-butyl ether (MET) to unleaded gasoline can help complete combustion of gasoline and reduce carbon oxide emissions. However, methyl tert-butyl ether causes central nervous system damage, which may cause organ damage and cancer in long-term inhalation or exposure to methyl tert-butyl ether. The Republic of China Patent Publication No. 200927912 discloses an environmentally-friendly and fuel-efficient oil for vehicles and rolling boats. The liquid fuel-saving concentrate containing the energy activator and 2-methyl-2-propanol is uniformly mixed with the fuel in the fuel tank, which can improve the incomplete combustion of the fuel. The toxicity and anesthetic properties of 2-methyl-2-propanol used in this patent are higher than those of common alcohols. Therefore, the environmentally-friendly and oil-efficient oils still have doubts about the human body and the environment. The Republic of China Patent Publication No. 200825163 provides an energy-saving powder utilizing the principle of sub-shocking, which has far-infrared and negative ion efficiencies, is treated by nanotechnology and is oxidized by zinc oxide, cerium oxide, carbonic acid 201219555 It consists of magnesium, potassium oxide, aluminum oxide, rare earth elements and trace elements. This kind of fuel-saving powder is composed of a variety of solid inorganic materials and must be treated by nanotechnology. In addition to the complicated process, it is more likely to cause problems such as incompatibility with fuel and uneven dispersion caused by self-aggregation. Other fuel additives also include metal oxides, transition metal oxides, and bicyclic aromatic compounds in which metal oxides (e.g., oxidized, oxidized) are used as the non-homogeneous catalyst 'bicyclic aromatic compounds as reducing agents. The transition metal oxide is reduced by a bicyclic aromatic compound to activate the metal oxide to improve the combustion efficiency of the fuel. However, the metal oxide used in this additive is also a toxic substance in addition to the higher cost, and the long-term use imposes a burden on the human body and the ring. Another additive is an organic compound (such as scorpion acid) that is completely soluble in the fuel. This additive reduces the density and viscosity of the fuel, helps the various insoluble components in the fuel mixture, and makes the fuel burn more. In addition to the complicated process, the current fuel additives still have doubts about the harm to the environment and users. Therefore, it is urgent to find a fuel additive that requires only a small amount of addition and is non-toxic and non-polluting. [Inventive content] Improvement of the composition and process of conventional fuel additives, damage to the environment and human health. The inventor of this case first thought of applying the concept of sublimation to fuel additives. After multiple tests, it was found to be non-toxic, = milk. An additive that enhances the combustion efficiency of liquid fuels with a small addition. Accordingly, it is an object of the present invention to provide an additive for enhancing the combustion efficiency of a liquid fuel 201219555, which comprises a human fuel, wherein #3 can be sublimed organically in a solid state. A sublimable organic compound and a liquid compound at atmospheric pressure and 45 ° C. Another object of the present invention is to provide a method for increasing the fuel economy of a liquid fuel, and the county can be sublimated. The organic compound is added to a liquid fuel, and the organic compound in the middle of the complex is at a pressure of at most atmospheric pressure and below 45C.

Medium == Ming by adding a sublimable organic compound to a liquid fuel: when the clothing/orphanity rises, the sublimable organic compound will be sublimated by the solid state: when the gaseous state is released from the liquid fuel, it will form in the liquid fuel. A turbulent flow: enhanced diffusion Brownian motion, which makes the liquid fuel uniform and hot due to turbulence and more easily converted into small molecules or gaseous molecules; &, through the sublimation of organic compounds, sublimation into gaseous compounds, The liquid fuel that can be converted into small molecules or gaseous molecules can be diffused and uniformly burned to improve the combustion efficiency of the liquid fuel. The sublimable organic compound contained in the additive of the present invention has the advantages of being non-toxic, low in odor, and having a small amount of addition, and does not cause environmental or human damage at all.
