Description

Cleaning solution composition for internal combustion engines {The cleaning solution composite for an internal-combustion engine}

The present invention relates to a composition for cleaning the interior of an internal combustion engine, and more particularly, the efficiency of an internal combustion engine is excellent due to the excellent cleaning effect of contaminants such as accumulations or oxidized waste generated inside the internal combustion engine during long term use of the internal combustion engine. The present invention relates to a cleaning liquid composition for an internal combustion engine, which can maximize not only the maximum but also its long life.

In recent years, the internal combustion engine has been widely used in various gasoline engines, diesel engines, propane engines, rotary engines and aircraft engines such as general cars, buses, trucks and motorcycles.

However, when the internal combustion engine is used for a long time, an oxidized waste material such as carbon black, which is generated by combustion of fuel, is deposited and accumulated in the internal combustion engine, or the oxidized waste material is mixed with a lubricating oil present in the internal combustion engine to have a high viscosity. It forms mucus and contaminates the internal combustion engine.

This phenomenon, that is, the accumulation of deposits inside the internal combustion engine or the internal contamination of the internal combustion engine, increases the frictional resistance inside the internal combustion engine and at the same time leads to a decrease in the airtightness and the compressibility in the combustion chamber, and thus the combustion chamber must be regularly maintained. Will cause minor deviations (time delays in ignition and valve operation) in the operation of the intake, compression, combustion and exhaust (valve system, rotary and sliding) mechanisms, resulting in incomplete combustion of the fuel.

Incomplete combustion of such fuels, in particular, increases fuel consumption and increases the generation of exhaust pollutants and smoke, including carbon monoxide and nitrogen oxides (especially worse in acceleration), causing serious environmental pollution problems. In particular, the noise of the vehicle body is also increased, resulting in a decrease in the efficiency and life of the internal combustion engine.

Due to the above problems, many methods for removing contaminants such as sludge and oxidative waste accumulated in the internal combustion engine have been proposed, and the most commonly applied removal method is to decompose parts of the internal combustion engine and attach or attach the components to the internal combustion engine. This method requires expertise and patience to clean and remove stuck contaminants and reassemble parts.

However, the above method not only takes a long time for the removal of contaminants such as sludge and oxidative waste accumulated in the internal combustion engine, but also does not easily clean and costly clean the sophisticated parts that are not easily decomposed or have micropores. There is a problem.

As a method for solving the above problems, a method of cleaning an internal combustion engine by putting a cleaning solution inside the internal combustion engine without disassembling the internal combustion engine has been proposed, and a representative cleaning method is a known cleaning method using a flushing oil.

However, the cleaning method using the flushing oil has the advantage that the cleaning can be performed without decomposing the internal combustion engine, but there is a disadvantage in that only the surface of the dirt is cleaned during the cleaning, and as a result, an excellent cleaning effect cannot be obtained.

Accordingly, the present inventors can be used interchangeably with the gasoline engine and the diesel engine in the "engine cleaner" of the Republic of Korea Utility Model Registration Application No. 99-24420, as well as the broby hose mounting port of the engine, PVC valve line mounting port or Application of the engine cleaner to increase the cleaning efficiency of the engine by injecting the engine cleaning liquid into the oil pump mounting port has been applied for maintenance has been received.

However, the above technology has the advantage of improving the cleaning efficiency compared to other conventional cleaning methods, but does not propose a specific cleaning power enhancement method for the cleaning solution itself, and the present inventors the present invention after research of the cleaning solution to enhance the cleaning power Came to complete.

The present invention is to solve the above-mentioned problems of the internal combustion engine is excellent in the cleaning effect of contaminants such as accumulation or oxidation waste generated in the internal combustion engine during long-term use of the internal combustion engine can not only maximize the efficiency of the internal combustion engine It is an object of the present invention to provide a cleaning liquid composition for an internal combustion engine so that its life can be sustained for a long time.

In order to achieve the above object, the present invention provides 1,1,1-trichloroethane (hereinafter referred to as TCE), methylene chloride (hereinafter referred to as MC) and aliphatic hydrocarbon compounds. It can achieve by providing the cleaning liquid composition for internal combustion engines which is comprised by mixing the mixture which was mixed equivalently and the lubricating oil for automobiles normally used in the ratio of 8: 2-9: 1.

At this time, TCE and MC are added to the surface of the deposit accumulated inside the internal combustion engine as well as to penetrate deep into the deposit so that the accumulated pollutants can be easily removed.

In the above, the TCE has a molecular weight of 133.42 g / mol, a boiling point of 74.1 ° C. in a standard state, and is generally used for washing metals or plastics, but is insoluble in water, and is used in combination with an appropriate organic solvent.

In addition, MC is a colorless liquid compound having a molecular weight of 84.94 g / mol, boiling point of 39.75 ℃ in a standard state, and is commonly used as a solvent, in particular for cleaning or washing liquid materials.

In the present invention, the aliphatic hydrocarbon compound is added together with the TCE and MC, wherein the aliphatic hydrocarbon compound increases the stability of the cleaning solution and lowers the surface tension to increase the penetration and spreadability of the cleaning solution. It is used to enhance the effect when washing water.

As the aliphatic hydrocarbon compound, an exerel series compound commercially available from Exxon Chemical Co., Ltd. may be used, and among the above exerc series, exerel 3307L (ACTREL 3370L; US EXXON CHEMICAL Co., Ltd.) may be used. desirable.

In particular, Actrel 3307L was developed by Exxon Chemical Co., Ltd. as a substitute for chlorine-based solvents. Its excellent stability, productivity, and very low surface tension make it excellent for penetration and spreading. It is very effective and is widely used as a cleaner.

As described above, TCE, MC and a hydrocarbon compound are equivalently mixed, and the mixture and the lubricating oil are mixed at a ratio of 8: 2 to 9: 1 to prepare a cleaning liquid composition for an internal combustion engine according to the present invention.

In this case, the lubricating oil is added to enhance the lubricity of the prepared detergent composition so that the detergent composition can penetrate to the minute and fine parts in the cleaning process.

In particular, when the mixing ratio of the mixture and the lubricating oil is less than 8: 2, the amount of the mixture exhibiting a relatively small washing action cannot be sufficiently seen, and a sufficient cleaning effect is not observed. Since the amount of lubricating oil is small, the lubricability of the cleaning composition is reduced, and the problem of not being able to see a sufficient cleaning effect to fine and sophisticated parts occurs. Therefore, the mixing ratio of the mixture of lubricant and TCE, MC and hydrocarbon compound equivalently is 8: It is preferable to set it as the ratio of 2-9: 1.

As the lubricating oil, any one can be used as long as it is commonly used as lubricating oil for an internal combustion engine. The cleaning composition for the internal combustion engine can be prepared by mixing and stirring in a general manner, and the mixing method and the stirring method are not particularly limited.

As described above, the method for cleaning the internal combustion engine using the cleaning composition according to the present invention first completely removes the engine oil from the internal combustion engine, and then, instead of the engine oil, injects the cleaning composition into the engine and supplies the composition through an oil passage. It is only necessary to circulate the entire interior of the engine for a period of time so that the composition is in contact with and frictionally reacted with the rotating part, the sliding part (each engine part).

At this time, the amount of the detergent composition prepared above is preferably used within the range of approximately 80% to 120% when the amount of engine oil to be used 100%.

More specifically, when introducing the cleaning method using the cleaning composition, first open the drain cock of the oil pan, drain all the engine oil, close the drain cock of the oil pan completely, and 80% to 120% of the amount of engine oil used. Positive compositions of the invention are injected from the engine oil injection port.

After the injection is completed, a separate circulation device is used to circulate the composition throughout the internal combustion engine for a period of time, for example, about 1 minute to 5 minutes, and the device is left for 10 to 30 minutes after stopping the circulation device. After circulating for 10 to 30 minutes using the circulator again, stop the circulator, open the drain cock and remove the cleaning liquid composition.

At this time, various devices may be used as the circulation device, but it is more efficient to clean using the "engine cleaner" of Korean Utility Model Registration Application No. 99-24420, which has been previously filed and determined by the present inventor. .

After removing the entire cleaning liquid composition as described above, using a flushing oil to circulate again for 5 to 20 minutes using a circulator to remove the remaining composition in the engine, and then replace the oil filter with a new Inject engine oil into the engine.

When the internal combustion engine is cleaned as described above, the engine is not only completely cleaned but also the frictional resistance of the engine rotating part and the sliding part is reduced through the above cleaning, thereby maximizing the efficiency of the internal combustion engine, thereby increasing fuel efficiency and increasing the internal combustion engine. It has the advantage of extending its life.
