Detailed Description
Exemplary embodiments will be described in detail herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of fuel additives and methods of producing the fuel additives consistent with certain aspects of the present disclosure as recited in the appended claims.
The specific mechanism of the compound plateau clean fuel additive disclosed by the invention is as follows: firstly, after the composite plateau additive is added into different fuel oil such as gasoline, diesel oil and the like according to a preset proportion, the activity of the additive of the composite plateau clean fuel oil additive can be quickly transferred to fuel oil molecular groups through the action of molecular Brownian motion and the like, so that the fuel oil molecular groups are dispersed and refined, the viscosity and the surface tension are reduced, the fuel oil atomization quality is improved, the contact area and the contact chance of the fuel oil molecular groups and oxygen are increased under the condition of the same oxygen content, and the air-fuel ratio of mixed gas is actually reduced. Secondly, under the condition of high temperature and high pressure in a combustion chamber, the active molecules of the compound plateau clean fuel additive can play the role of an initiator, can release activation energy at the moment of fuel ignition to generate a large number of free radicals, and simultaneously form a plurality of flame centers, thereby accelerating the rapid reaction of combustion and being more uniformly dispersed, reducing the phenomenon of incomplete combustion in local areas due to insufficient oxygen content, and sharply increasing the combustion reaction speed of fuel so that the oil mist air mixture can be more fully and uniformly combusted in the millisecond-level combustion process to achieve the extremely rapid degree (chain lock explosion). Under the scouring action of strong air flow of the mixed gas, carbon deposit deposited in the combustion chamber of the engine is gradually and effectively removed. In addition, micro water molecules in the fuel oil are decomposed under the conditions of high temperature and high pressure to generate hydrogen and oxygen, the hydrogen is combustible, the oxygen is combustion-supporting substances, and the hydrogen and the oxygen can continuously participate in subsequent combustion chain reaction, so that the chance of secondary combustion is increased, the shortage of oxygen content in air is made up to a certain extent, the fuel oil is completely and fully combusted under the anoxic environment in plateau, and the generation of carbon deposition is further inhibited. In conclusion, the composite type plateau clean fuel additive disclosed by the invention solves the problems that fuel cannot be sufficiently combusted and carbon deposition is increased in plateau anoxic areas.
