What are the common ways to remove carbon deposits

At present, the latest means to remove carbon deposits from automobiles is the cleaning of hydrogen and oxygen decarburizers, the most common of which are fuel treasure, hanging bottles (chemical agent carbon removal), and manual disassembly and removal. I will give you an analysis of the advantages and disadvantages of these carbon removal methods.

Hydrogen and oxygen decarbonizer: It is the latest research and development of clear carbon deposition equipment, using the characteristics of hydrogen and oxygen active gas, catalytic, oxygen-rich, non-corrosive, etc., for safe and efficient carbon removal, the current market coverage is very low, only some 4S shops and high-end maintenance factories have;

Fuel treasure: a fuel additive, and gasoline itself has the same concept of additives, according to the national standards required, a certain amount of fuel additives should be added in the fuel production process to ensure fuel combustion, control exhaust emissions. Fuel treasure is only added on the basis of the original additives, so that the quality of fuel combustion is better, the effect of removing carbon deposits, the effect of fuel saving, but not obvious, can be understood as a one-time use effect, that is, a tank of oil added fuel treasure, after using up this tank of oil, refueling, no longer add, the basic effect is gone.

Therefore, the service life is short, the frequency of replacement is high, the cost is high, and it is expensive;

Hanging bottle (chemical agent): It is a three-point poison of medicine, which we all know, if you use this chemical agent to remove carbon deposits, the effect is more obvious, but this carbon removal method uses the corrosiveness of the agent, corrosion and carbon deposits, and the same damage to the inside of the engine, resulting in damage to components or accelerated aging, but the frequency of use is not high, and the performance of the car is not obvious.

Manual disassembly and removal: This is the most primitive way to remove carbon deposits, and the removal effect is better, but the labor cost is very high and the man-hours are very long.

Personally, I am more optimistic about the hydrogen and oxygen carbon removal technology, and it may take a while for popularization to get more detailed information.

How to clean up the best way to clean up carbon deposits in automobiles.

Generally, the commonly used methods are: dismantling and washing, hanging bottle cleaning, and fuel additives.

1. Dismantle and wash. This method is very direct and rude, but it is generally sent to the 4S store for disassembly, the disassembly of the engine is more complicated, no matter what parts will affect its performance more or less every time it is disassembled, you need to ask a professional master to disassemble. The carbon deposits in the engine can be seen directly when dismantled and washed, and the cleaning will be relatively clean.

However, the cost will be relatively high, and it will also require technology.

2. Hanging bottle cleaning.

This method is also relatively common, the hanging bottle is to discharge the cleaning agent into the air intake, dilute and soften the carbon deposit to turn it into a slurry, and then burn it from the cylinder to discharge. Generally, the cleaning objects include the intake tract, throttle, intake valve, fuel injector, cylinder inside, etc., but the effect is not as direct and obvious as dismantling and washing.

3. Fuel additives.

The main function of additives is to drill into the pores of carbon deposits with the help of strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through exhaust gas after burning with fuel at high temperatures. Effective fuel additives such as PNF stock solution are non-corrosive, will not clog ternary, and have a relatively high level of safety.

If the carbon deposits are not cleaned up for a long time, the operation of the whole vehicle will be caused by the internal channel of the engine being blocked by carbon deposits, and the internal fuel injection of the car will not be smooth, so that the engine power will become worse, thereby reducing the power of the automobile engine, increasing the fuel consumption, and the combustion rate will be too low.

If you do not clean up the carbon deposits in time, it will not only cause a certain degree of harm to the car, but also the harm to the environment.

Too much carbon can also damage the car's engine and cause the car to shake. If carbon deposits continue for a long time, it will directly affect the valve hole of the internal pressure limiting effect of the automobile parts, or the overall use effect of the internal precision parts such as the injection system. Long-term carbon deposition can also lead to the failure of various auxiliary parts of the vehicle.

1. What is carbon deposit?

Carbon deposits are the build-up of carbon on engine components such as engine valves, intake manifolds, and fuel injectors. When the engine is working, some components in the gasoline will condense into glue carbon, and the condensed glue carbon will continue to accumulate, which will affect the normal operation of the precision engine management system.

2. Ways to slow down the formation of carbon deposition:

1.Use high-quality fuel. Because the main components of carbon deposits are wax and colloidal deposition in the fuel, the lower the colloidal content in the fuel, the better. But we can't change the quality of the fuel, but we can choose not to add unidentified cheap fuel.

2.Avoid driving at low speeds for long periods of time. If necessary, the high speed can be pulled at a regular time. The principle of pulling high velocity to eliminate carbon deposits is to speed up the air flow, which can take away a small amount of carbon deposits that are not firmly attached. The combustion temperature is increased so that part of the carbon deposits in the cylinder are burned.

3. The method of cleaning up automobile carbon deposits is as follows:

1. Engine dismantling and cleaning: In terms of effect, engine dismantling and cleaning is undoubtedly the most effective way to clean up carbon deposits, but the whole process requires a lot of time and energy. The engine needs to be disassembled, and then used detergent, ultrasonic, etc. to completely and thoroughly remove the carbon deposits on the parts, of course, the most expensive.

2. Car hanging bottle: hang a bottle-shaped tool above the engine, then pour the detergent into the bottle tool, and introduce it into the engine through the catheter to achieve the purpose of cleaning carbon deposits. However, if the engine has a high level of carbon deposit, this method can lead to blockage or damage to the three-way catalytic system.

3. Machine washing: inject the cleaning agent into a machine, and then touch the combustion chamber with machine pressure, let the cleaning agent react with the carbon deposit to dissolve, and then pump out the waste liquid. This method has a good effect on some serious carbon deposits, and there is no need to disassemble the engine, but the cost is higher, and the oil needs to be changed after cleaning.

4.Clean fuel additives: Proper addition of fuel additives can do a good job of preventing carbon build-up, but only if you choose the right fuel additives.

How can we exhaust the carbon deposits of the car?

First, the carbon deposition is not serious, and the disassembly-free cleaning method is used to clean by adding a special cleaning agent liquid.

Second, if the carbon deposition is serious, the method of removing the cylinder head to clean the valve and cylinder block should be adopted.

Take some precautionary remedies while driving to reduce carbon deposits as much as possible. 1. Use clean fuel that meets the label; 2. Cultivate good driving habits, and shift gears at more than 2000 rpm; 3. Regularly pull the high-speed to let the engine run at high speed to remove slight carbon deposits.

There are many ways to remove carbon deposits. For example: fill up high-quality gasoline, do not idle for a long time, run more high-speed, clean up regularly on time, etc.

It is recommended to do a non-dismantling cleaning of the air intake system every 20,000 to 40,000 kilometers under the condition that the regular maintenance is satisfied, and the carbon deposition operation is carried out on the parts of the vehicle that are easy to form carbon deposits, such as air intake, valve, and oil circuit. This effectively reduces the impact of carbon deposits on engine performance and keeps the "heart" of the car in optimal condition.

Carbon deposition includes two concepts: one is a coke-like substance produced by unsaturated olefins and gum in the fuel at high temperature during the working process of the engine. The second is carbon deposition in EDM, which should be avoided as much as possible in EDM, especially in precision mold processing.

What are the ways to remove carbon deposits?

1. Fill high-quality gasoline: impurities such as wax and gum in gasoline are the main components of carbon deposition, so the trend of carbon deposition in gasoline with high cleanliness is weaker. High grade does not equal high quality, that is to say, 97 oil is not necessarily less impurities than 93, the label only represents the octane number of the oil, not the quality and cleanliness.

In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This can effectively prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon deposits and slowly remove them, so as to protect the engine from damage. However, the addition of gasoline detergent must be cautious, if you add shoddy products, you will get the opposite effect.

2. Don't idle for a long time: If the idle time is long, the time for the engine to reach the normal temperature will be longer, and the evaporation rate of gasoline will be slow after being sprayed on the back of the valve, and carbon deposition will also be born. At the same time, if you are driving at idle speed, the air flow into the engine will be small, so the scouring effect on carbon deposits will also be weak, which will promote the deposition of carbon deposits.

3. Multi-run high-speed: The purpose of multi-run high-speed is to use the scouring effect of airflow on the inlet tract to prevent carbon deposition. In addition, increasing the speed of shifting gears is also similar to running at high speed, turning the original gear shift at 2000 into 2500 conversion, which can not only effectively prevent the generation of carbon deposits, but also improve the dynamics of the car, and also avoid the detonation caused by too low shift speed and protect the engine.

4. Pay attention to the timing of extinguishing the car: for the car equipped with a turbocharger, do not extinguish the car immediately after high-speed driving or climbing, and then extinguish the car after 10 minutes of idle operation, because the car equipped with a turbocharger forms carbon deposits several times faster than the general naturally aspirated car.

5. Clean up on time: If the carbon deposit has caused failure, such as idle jitter, difficult starting, high idle speed, excessive exhaust gas and other problems, it must be cleaned. Conventional vehicles must also be cleaned every six months or 10,000 kilometers to deposit carbon. Cleaning can be done with some no-dismantle cleaner.

The effective method of removing carbon deposits is walnut sand removal method. Motorists who are interested in this method can try it at some professional institutions.

Carbon deposits are harmful to the engine in many ways, and carbon deposits are caused by insufficient combustion of the combustible mixture in the engine.

Some cars have severe oil burning, which can also lead to increased carbon deposits in the engine.

Common parts of carbon deposition include valves, combustion chambers, throttle valves, air intakes, etc.

Riders are advised to clean up carbon deposits regularly to keep the engine in good working order.

If carbon deposits are in the combustion chamber, it will increase the compression ratio of the combustion chamber, which will lead to engine knocking, which will also lead to a decrease in engine power and an increase in fuel consumption.

Many engines use direct in-cylinder injection, which is more susceptible to carbon deposits.

Therefore, it is recommended that riders with in-cylinder direct injection engines regularly clean up carbon deposits.

You can also use some fuel additives to remove carbon deposits when using the car, which can reduce carbon deposits.

When you usually use the car, you can regularly go to a professional institution to clean up the carbon deposits.

The most effective way to clean up carbon deposits: 1. Clean the throttle, remove the throttle and use carburetor cleaning agent to clean it, dry it with a cotton cloth, and then grind and clean it; 2. Clean the carbon deposits inside the engine, open the oil cap, pour the whole tank of cleaner into the idle speed for 10-15 minutes, and then turn off the engine. Clean the carbon deposits inside the engine, detergent dissolves the sediments such as sludge, gum, moisture and metal debris inside the engine, and prolongs the life of the engine. 3. Cleaning the carbon deposition of the oil circuit before the blind land, including cleaning the fuel injector, combustion chamber, spark plug, and other parts.

The purpose of the answer is to solve the lack of power, fuel consumption, shaking, poor acceleration or start-up difficulties caused by carbon deposits, gum and dirt in the oil circuit system.

The impact of engine carbon deposition on the car is still quite large, first of all, to reduce the engine power, that is, to make the power output uneven and gradually decay, in other words, more and more powerless. The second is to increase fuel consumption and increase your financial burden. The third is the difficulty of cold start, that is, the difficulty of ignition, and it is not easy to get on the car.

Finally, serious carbon deposition in the combustion chamber will also cause cylinder detonation, and there will be a sound of low-speed acceleration, which will cause damage to the piston and crankshaft, thus seriously affecting the safety of the car. Then there is the excessive discharge, which not only fails the annual inspection and inspection, but also directly aggravates the harm of polluting the environment. The specific principle is that if you do not pay attention to the oil and driving habits for a long time, the wax and gum in the gasoline will accumulate thicker and thicker, and carbon deposits will be formed when they harden after repeated heating.

If the engine burns oil, or if the gasoline is of poor quality and has more impurities, the valve carbon deposits are more serious and form faster. Because the structure of carbon deposition is similar to that of a sponge, when the valve forms carbon deposition, a part of the fuel injected into the cylinder will be adsorbed, which makes the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and abnormal phenomena such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If it is serious, it will cause the valve to be closed loosely, so that there is no cylinder pressure in the cylinder and it will not work completely, and even adhere to the valve to prevent it from returning.

At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.
