How to clean up carbon deposits in automobiles? How to clean up carbon deposits in cars

How to clean up carbon deposits in automobile engines? I believe that this is a problem encountered by many friends who have a car, there are various methods on the Internet, and the effect is not how good it is.

<>First of all, the carbon deposition of the engine often appears in the **? The first is the oil circuit, which is mainly the oil circuit is some impurities produced by the oil; The second is the fuel injector, which will also form carbon deposits around it; The third is that carbon deposits will be formed in the cylinder, exhaust valve and intake valve; So how do you go about cleaning it up?

<> fact, sometimes you will find that the 4S shop will "hang the bottle" for the car, but the "hanging bottle" method is a quick way to clean up the carbon deposit, of course, the old driver does not recommend this method, because this cleaning method will make the carbon deposit broken is not particularly ruthless, so it will produce large particles of carbon deposit, then it may block the three-way catalysis, which has a certain impact on our exhaust emissions.

Older drivers are more recommended to use a reliable carbon deposition cleaner, because it is a long process, not mandatory to remove carbon deposition, but to moisturize things silently. When you pour it from the fuel tank, it is to remove your carbon deposits from the root, through the oil circuit will clean your oil circuit, to the fuel injector will clean the fuel injector, as well as the intake valve, combustion chamber, etc., will clean the carbon deposits, and then burn and then discharge out of the engine, so the use of this carbon deposit cleaner is to clean up the carbon deposits of your entire combustion chamber system, which can be said to be very good.

Of course, then again, there are many carbon deposition cleaner products sold on the market, so the old driver suggests that we must choose a reliable brand, if you feel that some brands are unreliable, then we should not use it, and if your friend or master recommends some better carbon deposition cleaner to you, then we might as well give it a try.

To know the best way to clean up carbon deposits, first know how it is created.

Why is carbon deposited generated? This is because the fuel itself contains gum, impurities, dust, moisture, etc., which accumulate over time to form sludge and other deposits in the fuel tank, oil inlet pipe, etc.; The second is due to the oxidation and polymerization of unstable components such as olefins in gasoline at high temperatures, forming colloidal and resinous viscous, which stays in the fuel injector, air intake valve, etc., and the deposit will become hard carbon deposits when burned. In addition, traffic congestion, cars are often at low speed and idling, which can aggravate the formation and exacerbation of carbon deposits and sediments.

If carbon deposits are not cleaned in time, carbon deposits and deposits will block the needle valve and valve hole of the fuel injector, resulting in poor closure of the intake valve, a drop in cylinder pressure or even tempering, resulting in unstable engine idling, increased fuel consumption and deterioration of exhaust emissions.

Carbon deposits on the piston top and cylinder head can easily cause local overheating of the combustion chamber and gasoline preheating, resulting in engine knocking and other failures. These failures can shorten the life of the engine.

The best way to clean up carbon deposits in your car:

1. In fact, the hanging bottle is filled with a pressurized atomized cleaning agent, and the cleaning agent is sent into the air inlet to carry out a "solvent dissolution" reaction with the carbon deposition of the throttle valve, fuel injector and other components, and then the carbon deposition is cleaned out of the engine by using the high engine speed, but the carbon deposition is very serious, which will cause the three-way catalytic system to be blocked or even damaged;

2. The use of detergent pours the cleaning agent into the machine, sprays it into the combustion chamber with machine pressure, allows the cleaning agent to react with the carbon deposit to dissolve, and then extracts the waste liquid, if the carbon deposit is very serious, the large carbon that falls can not be completely extracted, which may damage the combustion chamber;

3. It is best to use an effective release agent, which will clean the oil circuit and carbon deposits, and release the piston ring. If you want to use a PNF-type cleaner, you can release the piston ring.

The residue of substances in the fuel injector, throttle, oil pipeline, spark plug, cylinder head, inner wall and other parts caused by insufficient combustion of gasoline in the cylinder, and then the black gum produced by the repeated high temperature action of the engine is called carbon deposit.

One of the reasons for carbon deposition is that the fuel is not completely burned and adheres to various parts of the engine, which can form carbon deposits over time. The main function of additives is to drill into the pores of carbon deposits with strong surface activity, destroy their structure, and gradually dissolve these carbon particles from the metal surface, and then discharge them through the exhaust gas after burning with the fuel at high temperature.

The increase in carbon deposits in the car will lead to insufficient combustion of the engine, resulting in an increase in fuel consumption and a long time when the car failure light is on.

Ways to slow down the formation of carbon deposits:

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 removing carbon deposits at a high speed is to speed up the airflow, which can carry 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.

carbon deposition hazards; If the carbon deposit is not cleaned for a long time, the operation of the whole vehicle will be caused, the internal channel of the engine will be blocked by carbon deposits, the engine power will become worse, and the occurrence of fuel consumption, abnormal engine noise, and unstable idle speed will occur, thereby reducing the power of the automobile engine, increasing fuel consumption, and causing the combustion rate to be too low. If you do not clean up the carbon deposit in time, it will not only cause a certain degree of harm to the car, but also the harm to the environment, modern society pays attention to energy conservation and emission reduction, and exhaust emissions must not exceed the standard, so we should pay attention to this problem.

Usually 5000 kilometers with effective PNF fuel additives to clean the overall oil circuit carbon deposits, a long time not to clean up the carbon deposits will cause the operation of the whole vehicle, so that the internal channel of the engine is blocked by carbon deposits, the internal fuel injection of the car is not smooth, so that the engine power becomes poor, thereby reducing the power of the car engine, increasing fuel consumption, and the combustion rate is too low.

Please ask a professional repair shop to deal with it.

Generally, in use, be careful not to drive at low speed for a long time, and pull the high speed regularly, basically there will be no big problem.

The fuel consumption rate of carbon deposition is very high, and it also directly affects the performance of the internal combustion engine, and the noise increases! It is recommended to disassemble the valves, cylinder heads, pistons and other parts for re-grinding and installation

1. Running at high speed for a period of time in each gear 2. Going directly to the store for carbon deposition cleaning, in fact, running at high speed is the best choice.

The method of cleaning up carbon deposits in automobiles 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.

1. How to prevent carbon deposits

1. Fill with high-quality gasoline

Impurities such as wax and gum in gasoline are the main components of carbon deposits, so gasoline with high cleanliness has a weaker tendency to form carbon deposits. 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. Do not idle for a long time

The longer the idle time, the longer the engine reaches normal temperature, and the slower the rate of evaporation of gasoline when it is injected into the back of the valve, which creates carbon deposits. 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.

IIhazards of carbon deposits;

1.will increase the fuel consumption of the vehicle;

2.weaken the power of the engine;

3.When the vehicle is idling, the body is prone to shaking;

4.The exhaust emissions of the engine will exceed the standard;

5.When the engine starts, it is not easy to ignite;

6.When carbon deposits are severe, it can also cause damage to the engine's piston and crankshaft.

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

Clean the throttle, remove the throttle, clean with carburetor cleaner, dry with a cotton cloth, and install.

Clean the carbon deposits inside the engine, open the oil cap, pour the whole tank of cleaner into the fuel tank, and drive more to remove the carbon deposits.

Cleaning up carbon deposits in oil circuits includes cleaning fuel injectors, combustion chambers, spark plugs, etc.

Carbon deposits are mainly caused by insufficient combustion of gasoline. Many people's way of dealing with it is to go to the 4S store for high-pressure cleaning, so that although it can also be cleaned, the resulting cost is also extremely high. Engine carbon deposits can first be flushed with high-grade gasoline, because the combustion of this gasoline is relatively sufficient, which can effectively clean up the carbon deposits.

Generally speaking, there are two ways, one is to go to the store for professional construction, for the combustion chamber, fuel injector, throttle, three-way catalytic cleaning, this kind of construction requires certain professional equipment and professional cleaning agents. Another way is to use cleaning fuel additives, pay attention to the selection of cleaning additives, the general maintenance type of additives to inhibit carbon deposition effect is not obvious, after the addition of cleaning additives, after driving one or two tanks of oil, the removal effect of carbon deposition in the oil circuit will appear.

Now they are all dismantle-free cleaning, cleaning throttle valves, air intakes, three-way catalysis, etc.

Hello, it will be fine to clean with a special cleaning solution.

Cleaning with chemical cleaning or special cleaning agent.

Vehicle carbon deposition treatment method.

1. At present, there are only two ways to remove carbon deposits in the maintenance plant, one is to use the disassembly-free cleaning method when the carbon deposits are not serious, and clean them by adding a special cleaning agent liquid.

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

3. One is to drive yourself and take some preventive remedial measures to reduce carbon deposition as much as possible. Use clean, compliant fuel; Cultivate good driving habits, and the manual shift should be above 2000 rpm; Regularly pull the high speed to let the engine run at high speed to remove slight carbon deposits. Methods for removing carbon deposits from automobile engines.

4. Pull the high-speed: for the high-speed, the platform has expressed its views before, often running the high-speed, pulling the high-speed can slow down the generation of carbon deposits, at most the carbon deposits that have just been produced have a scouring effect, but there is almost no cleaning effect on the carbon deposits that have been produced for a long time. However, most of the riders still say that pulling the highway can clean up the carbon deposits, so the highway is also counted as a method here.

5. Hanging bottle cleaning: At present, the most commonly used disassembly-free cleaning method, because it is a bit similar to human dripping, this cleaning method is named, which is commonly known as dripping and hanging bottles. It is convenient and fast, and the cleaning effect of the fuel injector is obvious.

For new cars, the cleaning effect of dripping can generally reach about 80, and the effect of old cars is slightly worse, but the effect on power and fuel consumption after washing is still obvious.

6. Walnut sand cleaning carbon deposit: Walnut sand is the fine particles made by processing the walnut shell. The principle of cleaning carbon deposits with walnut sand is to load walnut sand into the equipment, the equipment uses compressed air as the power, establishes the working pressure in the pressure tank through compressed air, presses the walnut sand into the sand pipe through the sand harvesting, sprays it out at high speed in the nozzle, and sprays it into the intake tract of the engine.

Because the valve of the cylinder has been closed before cleaning, the high-speed walnut sand will be hit and scraped in the closed airway, so that the carbon deposits on the valves and inlet channels will be beaten down and washed down, and finally the walnut sand and carbon deposits are sucked out together by using the suction device that comes with the equipment, so as to achieve the purpose of cleaning the carbon deposits.
