Problems solved by technology

[0004] The obvious increase of the total deposits in the gasoline engine combustion chamber will increase the engine compression ratio, and it is not easy to decompose and affect heat dissipation, resulting in an increase in the temperature of the gas after compression in the combustion chamber and an increase in ORI (the engine's demand for octane number). Increase the mechanical friction between the top of the piston and the missing cover, and knock the cylinder, which will eventually lead to increased fuel consumption and worsened emissions of the engine

Embodiment 1

[0025] The high surface active polyisobutylene amine used is Keropur PIBA from BASF Company in Germany, the high surface active polyether amine used is SURFONAMINE FLK-1000 from HUNTSMAN Company in the United States, the wear reducer used is H6457 from Afton Company, and the oil used is The soluble polyether carrier liquid is a copolymer of propylene oxide with a C / 0 above 3.5 and a weight-average molecular weight of 800-1200. Cosolvents, antioxidants, rust inhibitors, preservatives, and demulsifiers are all typical commercially available product.

[0026] The mass percent of each component is:

[0027]

[0028]

[0029] Weigh the above required components in proportion, mix them at room temperature or not higher than 60°C, and stir evenly until transparent to obtain the gasoline detergent of the present invention. Add this additive to the market at a dosage of 350-440ppm 93 # In gasoline, the physical and chemical analysis data of the oil products all meet the require...

Embodiment 2

[0031] Use the high surface activity polyisobutylene amine, polyether amine and gasoline antifriction agent of embodiment 1, repeat the preparation method of embodiment 1, prepare the mass percent of each component of gasoline detergent of the present invention as follows:

[0032]

[0033] Add this additive to commercially available 93 by 380-450ppm # In gasoline, the physical and chemical analysis data of the oil products all meet the requirements of GB17930-2006 after inspection by the professional inspection department. The reduction rate of simulated intake valve deposits is 98%. Using high-temperature (above 500°C) thermogravimetric analysis to simulate the incremental change of combustion chamber deposits, it is 92.8% lower than the current commercially available gasoline additives.

Embodiment 3

[0035] Use the high surface activity polyisobutylene amine, polyether amine and gasoline antifriction agent of embodiment 1, repeat the preparation method of embodiment 1, prepare the mass percent of each component of gasoline detergent of the present invention as follows:

[0036]

[0037] Add this additive to commercially available 93 by dosage of 60-500ppm # In gasoline, the physical and chemical analysis data of the oil products all meet the requirements of GB17930-2006 after inspection by the professional inspection department. The reduction rate of simulated intake valve deposits is 96%. Using high-temperature (above 500°C) thermogravimetric analysis to simulate the incremental change of combustion chamber deposits, it is 91.8% lower than the current commercially available gasoline additives.

[0038] In summary, the formulations of 3 embodiments of the present invention are added to the currently commercially available motor gasoline at 220-550ppm by dosage, which ha...

Abstract

The invention relates to a gasoline additive capable of remarkably reducing the precipitate in a gasoline engine combustion chamber. The gasoline additive comprises PIBA with high surface activity, polyether amine, gasoline anti-friction composition, polyether carrier liquid with excellent oil solubility, antioxidant, antirust agent, preservative and emulsion breaker. The weight percentages of the components are as follows: 15 to 30 percent of PIBA, 15 to 30 percent of polyether amine, 2 to 10 percent of gasoline anti-friction composition, 15 to 40 percent of polyether carrier liquid and 20 to 40 percent of cosolventk and other functional agent. When 220 to 550 ppm of the gasoline additive is added into the gasoline for the car sold in the market, the accumulated carbon in an oil nozzle and an air inlet valve can be washed, the precipitate in the gasoline engine combustion chamber can be obviously reduced, the mechanical friction loss can be reduced, and the power can be enhanced. The increment of the precipitate of the car gasoline containing the gasoline clearing agent in the combustion chamber can be reduced by more than 50 percent, the running noise of the machine can be effectively lowered, the power can be obviously enhanced, and an energy-saving and emission-reducing effect can be realized.

Description

technical field [0001] The invention relates to a gasoline additive for vehicles and a preparation method thereof. The gasoline additive has high surface activity polyisobutene amine, polyether amine and gasoline friction reducer as main active ingredients. The invention also relates to a preparation method of the additive and its use in motor gasoline. technical background [0002] Entering the 21st century, with the development of the automobile industry, the number of automobiles in our country has increased rapidly. While automobiles bring convenience to people's work and life, they also increase the consumption of petroleum resources and the emission of harmful exhaust substances. How to keep the car in good working condition, make gasoline burn more fully, reduce fuel consumption, and reduce exhaust emissions, which requires the fuel intake system of the car engine to be kept clean for a long time, so gasoline additives should be added to the gasoline used. [0003]...
