Abstract

This invention relates to new cleaning oil for engines, which is composed of one or many of ordinary motor-oils as the basic oil: 150SN, 500SN, 650SN, 150BS and advanced motor-oil from south Korea: SK70n, SK150N, and SK100N, anticorrosive, oxidation inhibitor, antiwear agent, detersive pour-point depressant and freely selected defoamer agent. In preparation, a computer is used to control the volume of the additives and the regulation temperature so that, they can fully contact with each other and interfuse with each other to get the target of the engine oil standard.

Description

An engine cleaning oil

TECHNICAL FIELD

The present invention relates to an engine wash oil.

BACKGROUND ART

Engine oil during use, due to the long working friction high temperature oxidation, Produce metal powder, gum, impurities, water, fuel and lubricants mixed with dilution and other phenomena, Which deteriorates the quality of the lubricant can not be used. Long-term engine friction, wear to the engine build Into a very serious loss, long periods of cleaning will cause engine damage, make safe driving by Great impact.

Currently cleaning the engine has the following methods: 1, kerosene, diesel oil cleaning, Easy to fire, very dangerous; 2, chemical cleaning, chemical cleaning agents on the engine corrosion, There decomposition of the lubricant; 3, mechanical cleaning, is not complete; 4, open the engine wash, Time-consuming and costly. Several methods to overcome the above disadvantages, to provide a cleaning Is short, low cost, good compatibility with high-end lubricant engine cleaning oil, is a new Subject.

SUMMARY OF THE INVENTION]

The present invention is to solve the technical problem is overcome in the engine cleaning methods exist The downside, to provide a convenient, low cost, and compatibility of the effect of existing oil Well, retained some cleaning oil can play a role in protecting the engine clean engine oil.

To solve the above problems, the present invention adopts the following technical solution:

Clean engine oil of the present invention, the percentage by weight, which contains 79.5% -91.5% of the The total amount of base oil and additives of 8.5% -21.5%. Ratio of the base oil is preferably 88%, 12% of the total additive.

The invention described in the engine cleaning oil base oil as an ordinary oil 150SN, 500SN, 650SN, 150BS in one or more of.

Additives include 3-5% by weight of the metal detergent, 1-6% by weight of Antiwear agents, 3-5% by weight of a dispersing agent, 1-3% by weight of an antioxidant by weight 0.1-1.5% total of pour point depressant and 0-1% by weight of the defoamer. Preferably, the additive package Including by weight of a component of the following: 5.0% of metal detergent, 1.0% anti-wear agent, 4.0% dispersant, 1.5% antioxidant, 0.5% and 0.5% antifoam depressant.

Metal phenate detergent can be used, such as sulfurized alkylphenol calcium, calcium alkyl salicylate, It will be attached to the mechanical surface sediments, such as coke, paint and other impurities wash down.

Antiwear agents can be used sulfur, phosphorus or silicon boron salts, such as long-chain primary alkyl thiophosphate Zinc, which makes the engine rust after cleaning the surface layer of the protective film on the engine wear their Wear protective effect.

Dispersing agent may be used diimide such as succinimides, polyisobutylene succinimide Imine, it will wash off the impurities, the solid particles are dispersed in the oil, and then through the oil With the engine.

Antioxidants can be used in alkaline zinc parathion dual Sim, molybdenum salt or a copper salt, for example, dioxane Base zinc dithiophosphate, the role to prevent oil temperature metamorphism.

Pour point depressant is polymethacrylate 0.1-1.5% clean oil can flow easily.

Optionally add a defoaming agent, an antifoaming agent of silicone oil can be used, for example, methyl silicone oil, methyl Silicone oil esters, is to eliminate the bubbles.

The present invention can be cleared only cleaning the oil inside the engine deposits, sludge, paint, add Dust into the air impurities, metal powders produced by the friction of metal and other attachments, and Increased engine protection, cleaning the engine oil with the usual high-end engine run Oil chemical reaction does not occur, a better compatibility, even after cleaning cleaning residual oil Does not affect the engine performance and life, and will improve engine wear antirust function.

The invention of the engine cleaning oil, easy to use, easy to operate, saving time and effort, expense Inexpensive, can be extended engine overhaul period 2-4 times

[Description of Embodiments]

Clean engine oil of the invention is determined by a variety of lubricating base oils and additives made The. Example 1-3 base oil ingredients are used in Shanghai, Dalian, Daqing, and South Korea's SK public Our products. All additives for the United States Lubrizol, ethyl, Infineum products. Used Detergents to Jiangyin Kangtai Lubricant Additives Co., Ltd. products T115B, antioxidants mining Run by the Friends of Nanjing Chemical Additives Co., Ltd. products T203, alias ZDDP.
