Technical Field

The invention belongs to the technical field of fuels, and particularly relates to a novel gasoline additive, a preparation method thereof and a mixed fuel.

Background

The gasoline is non-renewable petroleum resource and is prepared by processing and blending in an oil refinery. For hundreds of years, the main components of the oil product are carbon and hydrogen without oxygen. The fuel oil vehicle engine mainly uses the sucked air to support combustion by using the oxygen in the air, and the air is over 70 percent of nitrogen, and the oxygen only accounts for about 20 percent. The time of each stroke of the four-stroke engine is calculated according to milliseconds, combustible gas in a cylinder is sucked under the condition of high speed oxygen deficiency, and the combustible gas cannot be completely combusted to apply work, so that energy is wasted, and emission pollution is caused. For example, carbon monoxide in the exhaust gas is not generated by oxygen-deficient combustion, and the thermal efficiency is only half of that of the exhaust gas. If the valuable petroleum resource is used as the raw material of organic chemical industry, the valuable resource can be fully utilized and the fuel can be burnt unfortunately.

With the development of society and the progress of science and technology, human beings more and more fully realize the silly practice of wasting energy and polluting the environment. How to make full use of the energy brings the effect of environmental protection again, further improves the thermal efficiency of engine for the fuel fully burns, but the space of reforming transform is limited, and tail gas filters also and addresses the symptoms and does not address the root cause, and we will pick up from the source and change into the fuel from the oxygen suppliment burning by traditional dependence outside oxygen suppliment, make the main cost of oil change into the rational structure of carbon, hydrogen, oxygen.

Therefore, the search for alternative clean energy sources has become a major issue facing the world today. The novel energy such as ethanol gasoline which is rapidly developed in recent years provides a new idea for solving the problems of shortage of petroleum resources and serious environmental pollution. Because the fuel quality of China is generally poor, the fuel contains sulfur, phosphorus and other impurities, and chemical components can form chemical complexes on the surface of an oxygen sensor and in the three-way catalyst along with the discharge of waste gas after combustion.

Due to a plurality of factors, after the automobile runs for a period of mileage, besides carbon deposit is generated in an intake valve and a combustion chamber, faults such as poisoning failure of an oxygen sensor and a three-way catalyst, blockage of the three-way catalyst, blockage and clamping of an EGR valve by sediments and the like can be caused, the engine works abnormally, and the problems of oil consumption increase, power reduction, over-standard tail gas and the like are caused.
