Embodiment 1

[0023] Example 1 Component selection of gasoline additive main agent.

[0024] Add different main ingredients of additives to base gasoline (Sinopec Guoer No. 93 gasoline) to obtain different gasoline additive formulations. As shown in Table 1, formula A is a formula obtained by adding polyetheramine to base gasoline at a ratio of 3:2000; formula B is a formula obtained by adding polyisobutylamine and polyisobutene amine to base gasoline at a ratio of 12:3:10000. The formula obtained from propylene glycol; formula C is the formula obtained by adding polyetheramine, polyisobutylamine and polypropylene glycol to the base gasoline at a ratio of 15:12:3:20000.

[0025]

[0026] The formula A, formula B and formula C are respectively subjected to the simulation test of the cleaning rate of the intake valve deposits. The test equipment is the L-2 simulated intake valve deposit bench in Appendix B of GB19592-2004. The test methods include:

[0027] A: Weigh the sediment collect...

Embodiment 2

[0033] Embodiment 2 The ratio selection of each component in the gasoline additive main agent.

[0034] The various components in the gasoline additive main agent are mixed according to different proportions, and then the driving test of the change of the combustion chamber deposit is carried out. The specific method is as shown in Example 1, and the results are as follows figure 2 shown. Among them, formula D is the formula obtained by adding polyetheramine, polyisobutylene amine and polypropylene glycol to the base gasoline at a low ratio of 15:12:3:20000; formula E is to add 10:4:1 to the base gasoline: The high proportion of 5000 is a formula obtained by adding polyetheramine, polyisobutylamine and polypropylene glycol. from figure 2 It can be seen that the control effect of the gasoline additive with a high proportion of the main agent on the combustion chamber deposits is stronger than that of the gasoline additive with a low proportion of the main agent. On the bas...

Embodiment 3

[0035] Example 3 The effect of friction modifiers on gasoline additives.

[0036] Formula E and formula F are respectively carried out driving test of combustion chamber deposit change, and specific method is as shown in embodiment one, and result is as follows image 3 shown. Among them, formula E is the formula obtained by adding polyetheramine, polyisobutylene amine and polypropylene glycol to the base gasoline at a ratio of 10:4:1:5000; formula F is the formula obtained by adding 10:4:1:1 to the base gasoline: The formula obtained by adding polyether amine, polyisobutylene amine, polypropylene glycol and ULTRAZOL? 9525A friction modifier at a ratio of 5000. By comparison image 3 -E and image 3 -F shows that adding an appropriate amount of friction modifier can enhance the cleaning effect of gasoline additives on combustion chamber deposits.

Abstract

The present invention provides a gasoline additive that cleans the burning chamber, including 12.5 ~ 25 volume polyethamine, 0.2 ~ 0.4 lactifer breaking agent, 0.2 ~ 0.4 stabilized rust -proof agent, 33.4 ~ 59.4Environmental protection from the digital number.The gasoline additives of cleaning the burning room sedimentary material provided by the present invention are non -corrosive, good safety performance, environmental protection without pollution, and low cost. While effectively controlling the formation of nozzles and air intake valve sediments, it can effectively clean the burning room depositionThings can improve the driving performance of the vehicle and have a broad application prospect.

Description

Technical field [0001] The present invention involves gasoline additives, especially for gasoline additives and how it uses a gasoline sedimen of the burning room. Background technique [0002] Affected by the refining process and equipment, the olefin content is high among my country's car gasoline, which is much higher than the standard gasoline standard for developed countries in Europe and the United States.Highlyna content gasoline is prone to form an intake system sedimen and burning room sediments in use, resulting in decline in engine performance, increased fuel consumption, and worsening emissions. [0003] To this end, people take different methods to clean the deposits of the fuel system.Disasuring and cleaning methods may cause metal corrosion and destroying the precise coordination of the original parts, and the cleaning cycle is long, the cost is high, which is not good for the health of the repairman.Foam cleaning agent cleaning method, inject the water -based foam...
