Description

A kind of combustion adjuvant and preparation method of gasoline

Technical field

The invention belongs to the combustion adjuvant technical field of gasoline, the combustion adjuvant and preparation method of specially a kind of gasoline.

Background technique

It is extensive under the background that petroleum resources are increasingly depleted, Global Oil reserves increasingly decline, and with oil-burning machine It uses, China is growing day by day to the demand of fuel oil, while the utilization rate of the oil product in China, especially motor vehicle fuel is general All over lower, this not only causes the waste of fuel oil, while also result in the atmosphere pollution of the generation due to pollutant of vehicle exhaust The problem of aggravation.When automobile engine operates, atomizer temperature is at 100 DEG C or so, and intake valve temperature is between 200-300 DEG C. At such temperatures, the labile element in fuel oil, easily generation oxidative dimerization, generate colloid and carbon distribution, are deposited in On intake valve and atomizer, engine is easy to produce carbon distribution.The deposit being deposited on intake valve will cause inlet channel section Product is reduced, and intake efficiency reduces, and power decline can make valve event slow, be not closed completely when serious.Atomizer carbon distribution can make Oil spout is unsmooth, fuel-oil atmozation quality decline, after causing fuel oil to enter combustion chamber, it is difficult to which completely burned causes engine start tired Difficulty, unstable idle speed and oil consumption increase, and exhaust emissions deteriorates, and especially in winter, these situations are more obvious.Traditional solution Method is cleaned after disassembling engine, more bothersome, therefore adds combustion adjuvant in the oil, improves the burning of gasoline Rate, the development of combustion adjuvant are also increasingly to receive an acclaim, and do not require nothing more than the fuelling rate that can effectively improve automobile, and be not susceptible to gold Belong to precipitating, causes grease, but existing combustion adjuvant has certain due to being added to various additives in terms of environment Pollution.
