Abstract
The invention relates to the technical field of engine cleaning agents, in particular to a carbon deposition cleaning agent for an engine, which comprises the following raw materials in parts by weight: 10-20 parts of surfactant, 1-10 parts of carbon deposition microbial inoculum particles, 1-5 parts of compatilizer, 1-5 parts of active additive, 2-12 parts of friction agent and 20-60 parts of base oil, and the surfactant is used for chemical emulsification to loosen the carbon deposition; the carbon deposit is physically rubbed by using a rubbing agent to fall off; the carbon deposition microbial inoculum particles are used for carrying out biodegradation on the carbon deposition, thereby thoroughly cleaning the engine. The cleaning agent is prepared by mixing the compounded surfactant, the cultured carbon deposition microbial inoculum particles and the friction agent, the process is simple and easy to obtain, and the carbon deposition cleaning is thorough by combining three cleaning modes of physical cleaning, chemical emulsification and microbial degradation.

The invention relates to the technical field of engine cleaning agents, in particular to an engine carbon deposition cleaning agent and a preparation method thereof.
Background
The fuel oil and air in the combustion chamber of the engine are mixed and then combusted, because of factors such as atomization effect, part of smoke generated after combustion is discharged, the other part of smoke forms carbon deposit and is deposited on an object, when the smoke is deposited on the surface of the object with lower temperature (such as nearby a swirler and a nozzle), soft carbon deposit can be generated, and when the smoke is deposited on the surface of the object with higher temperature (such as the wall surface of certain high-temperature area of a flame tube in the combustion chamber), hard carbon deposit can be formed through coking.
The components of carbon deposit are complex and mainly contain hydroxy acid, asphaltene, oil coke, ash and the like. After the carbon deposition is formed, the normal operation of an engine can be seriously influenced, the power of a motor vehicle is reduced, the use reliability of the motor vehicle is damaged, the piston is locally overheated due to the carbon deposition, and the piston can be damaged in serious cases.
At present, the cleaning method of carbon deposition mainly comprises a mechanical method and a chemical method. The mechanical method is generally mechanical tool cleaning and soft and hard abrasive particle cleaning. This method has a low productivity, and is not easy to remove the soot from the piston portion which is hard to be touched by the tool, and the piston surface cleaned by this method leaves scratches which become new soot forming centers in the subsequent application.
The chemical method generally adopts strong acid and strong alkali and other reagents for cleaning. Because parts such as an air valve, a piston, an oil nozzle and the like of a motor vehicle are mostly made of alloy, reagents such as strong acid, strong alkali and the like can cause irreversible damage to the parts, for example, the strong acid and the strong alkali have a corrosion effect on an aluminum piston of the motor vehicle and cannot be compensated, the carbon deposition removing effect of the existing chemical carbon deposition cleaning agent is not thorough, and the carbon deposition can be removed only by soaking for a long time, so that the use of the chemical carbon deposition cleaning agent is limited. Therefore, the development of the carbon deposit cleaning agent with complete cleaning effect and no corrosion has very important significance.

Test experiments
In order to illustrate the effects obtained by examples 1 to 5 and comparative examples 1 to 3 prepared according to the present invention, performance tests were performed using the cleaning agents prepared in examples 1 to 5 and comparative examples 1 to 3 to verify the performance and application effects thereof.
1.1 test indexes and methods
The main evaluation indexes of carbon deposition are as follows: (1) CO 22The content of (a). CO 22Is the product of the complete combustion of the mixture, and the content of the product is the direct reflection of the combustion efficiency of the engine. CO 22The content of (A) is generally 13% to 19%. Under the influence of carbon deposition, CO2The content of (b) may decrease. (2) The content of CO. Under the influence of carbon deposition, gasoline is insufficiently combusted, resulting in the generation of a large amount of CO. (3) HC and NOx content. The hydrocarbon is one of the components of the gasoline, and if the tail gas contains a large amount of hydrocarbon, the gasoline is not combusted sufficiently and is discharged along with the tail gas. The detection method comprises the following steps of comparing and measuring the carbon deposition area on the surface of the cleaned engine piston; GB 18285 & 2005 & ltemission limits and measurement methods of pollutants in exhaust gas of spark ignition engines (double idling method and simple operating mode method) & gt; DB44/592 & 2009 emission limits and measurement methods (steady state operating methods) for automotive exhaust pollutants with spark-ignition engines.
1.2 test results
The test results show that the cleaning agent reduces the CO% of the tail gas of the engine after cleaning by over 90 percent, and the CO% is reduced2The% is maintained at 10.3-10.9, HC% is reduced by more than 76%, NO is reducedXThe percent is reduced by more than 50 percent, the reduction rate of tail gas and waste gas is high, carbon deposition in an engine is less, and the cleaning effect is obvious.
Compared with the examples 1-5, the comparative example 1 does not add carbon bactericide particles, the chemical emulsification cleaning of the carbon by using the surfactant and the physical friction removal of the carbon by using the friction agent are carried out, and the analysis shows that the cleaning effect is not ideal, and the CO content, the HC content and the NO are not idealXThe content is only slightly reduced, and the engine still has much carbon deposition, so that the gasoline is not fully combusted, and the exhaust gas rate is high.
Comparative example 2 compared with examples 1-5, comparative example 2 has NO abrasive, the cleaning effect is faster but not ideal, and the CO content, HC content and NO content are not ideal, and the microorganisms of the carbon deposition microbial inoculum particles degrade and remove the carbon deposition by utilizing the surfactant to chemically emulsify and clean the carbon depositionXThe content is only slightly reduced, and the engine still has much carbon deposition, so that the gasoline is not fully combusted, and the exhaust gas rate is high.
Comparative example 3 compared with examples 1 to 5, comparative example 3 is not added with a compatilizer, the surfactant, the abrasive and the carbon deposition microbial inoculum particles are used for degrading and removing the carbon deposition, and analysis shows that the cleaning effect of the cleaning agent is gradually reduced along with the prolonging of the cleaning time, the carbon deposition microbial inoculum particles are not contained in the abrasive, so that the carbon deposition microbial inoculum particles are damaged along with the cleaning, the cleaning effect is not ideal, and the CO content, the HC content and the NO content are not idealXThe content is only slightly reduced, and the engine still has much carbon deposition, so that the gasoline is not fully combusted, and the exhaust gas rate is high.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
