I believe that many car owners have such a situation. One is that when refueling at a gas station, they will hear someone promoting fuel treasures and talking about the dangers of carbon deposits in the engine; the other is that during maintenance, the 4S shop staff will talk And your vehicle has a lot of carbon deposits, it is recommended to do an engine carbon deposit cleaning, and talk about the danger of engine carbon deposits.

Therefore, carbon accumulation has become an annoyance for car owners. Some car owners don't care about it, and some car owners will buy fuel oil treasures or even regularly clean them at 4S shops. In fact, these cleaning methods are incorrect, especially not caring about the carbon deposits in the engine is wrong; now let me briefly introduce the correct cleaning of carbon deposits in the engine-dry ice decarbonization technology.

First of all, let's understand what engine carbon deposit is and how it is produced; engine carbon deposit is a very complex physical and chemical reaction, no matter how gasoline is purified, there are impurities, which cannot be completely burned, and impurities stay on the engine for a long time Next, due to the oil absorption of impurities, carbon deposits are formed; in addition, the sealed oil plug cannot be completely sealed, and oil vapor impacts the combustion chamber, otherwise complete combustion will accumulate on the engine and form carbon deposits.

From the above simple understanding, it can be found that engine carbon deposits are caused by incomplete combustion of impurities in the fuel; then what is the most effective way to clean the engine carbon deposits; if the engine carbon deposits are serious, it will be difficult to start a cold car and fuel consumption will increase. , it is difficult to speed up; at present, the fuel treasure is most used by car owners, and it is handed over to the 4S shop for cleaning. In fact, many fuel treasures on the market are substandard products, and they cannot clean the carbon deposits in the engine. Most of the 4S shop cleaning is hanging bottles Cleaning engine carbon deposits is a simple method, but the cost of cleaning is relatively high for car owners, and the cleaning effect is not ideal. Some may dismantle the engine for cleaning, and then use walnut sand or chemicals to clean it. Let’s discuss these two together. method.

Chemicals can clean carbon deposits well, but chemicals are corrosive, which will affect the tolerance of the engine. In addition, the secondary cleaning cost of chemicals is extremely high, and it is easy to age the rubber parts inside the engine, resulting in shortened service life of the engine. .

The walnut sand cleans the carbon deposits. The walnut sand is introduced into the machine and the high-pressure air is used to make the walnut sand run at a high speed. The carbon deposits collide with the walnut sand, and then the purpose of cleaning is achieved. Because the walnut sand is abrasive, it will also affect the tolerance of the engine. Cleaning The effect is not very satisfactory, especially the carbon deposit on the engine intake valve cannot be cleaned, which may cause the legacy problem of walnut sand;

Dry ice cleans engine carbon deposits. The raw material for cleaning is carbon dioxide. Carbon dioxide is processed by a machine to form solid dry ice. Then, the high-pressure gas of the air compressor is used to spray dry ice particles onto the carbon deposits. Using the principle of physical expansion and contraction of dry ice, the dirt is removed from the The surface of the object is peeled off, and then the sublimation gas carbon dioxide is very convenient to clean, and the cleaning cost is low, and there will be no secondary pollution due to cleaning; therefore, dry ice cleaning engine carbon deposits is the best way at present, and it can be cleaned without disassembly. Finally, it is recommended Everyone, when the vehicle has driven to about 20,000 kilometers, it is necessary to clean the carbon deposits regularly, which will save costs for your car maintenance; the above methods for cleaning engine carbon deposits hope to help solve the troubles of most car owners.
