Don t be misled about how to clean up carbon deposits in your car

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

One is to take some preventive remedial measures to reduce carbon deposits as much as possible, 1. Use clean fuel that meets the label; 2. Cultivate good driving habits, and the hand wave shift should be above 2000 rpm; 3. Regularly pull the high-speed to let the engine run at high speed to remove slight carbon deposits.

1. Hazards of carbon deposition (1) Carbon deposits accumulate in the starting nozzle of the pre-combustion chamber, which will block the nozzle hole and make it difficult for the engine to start; (2) The fuel injector accumulates carbon deposits, which is easy to jam the fuel injector, causing the engine to run without cylinders or suddenly shut down; (3) Carbon deposition on the top of the piston will form many hot surfaces, causing pre-ignition and deflagration, and shortening the service life of the engine; (4) Carbon deposition in the cylinder head will reduce the cooling effect of the engine, and greatly reduce the power and economy of the engine; (5) Excessive carbon deposition in the spark plug, after the fuel is wetted, it is equivalent to the parallel shunt resistance between the spark plug electrodes, resulting in the spark plug leakage and cannot work; (6) Carbon deposition in the piston ring groove will make the piston ring side gap and backlash smaller, or even no gap; Cause the piston ring to be cemented and lose its elasticity, and even break the piston ring and pull the cylinder; (7) Carbon deposition and gelatinization of the valve guide and valve stem will accelerate the wear of the valve stem and valve guide, and even cause the valve stem to move astringently in the valve guide and get stuck; (8) Carbon deposits accumulate on the working surface of the valve and its seat ring, which will cause air leakage due to loose valve closing, and the engine is difficult to start, weak to work and easy to ablation of the valve.

The simpler way is to add 1 point of fuel additives when adding gasoline, the purpose is to clean the intake tract and fuel injector, the effect is still very good. But in the case of the throttle, it is better to remove it and clean it.

Drive your car to a workshop for a professional maintenance person to inspect and clean it, and they will professionally remove the valve and engine to check for carbon deposits. If you are not a professional, you should not easily disassemble it yourself, and unprofessional methods will cause greater damage to the performance of the car. Piston carbon deposits:

It mainly includes carbon deposition at the top of the piston and carbon deposition on the piston ring, and the top of the piston is subjected to fuel combustion, which has the same properties as carbon deposition in the combustion chamber. The piston ring carbon deposition is mainly the product of engine oil and high temperature, because the piston is constantly heated when the engine is working, and the temperature is very large, once the car has serious carbon deposition, there will be a lot of parts involved. Such as, throttle valves, fuel injectors, spark plugs, intake and exhaust valves, combustion chambers, pistons, piston rings, cylinder blocks, etc.

You need to go to the 4S store for professional carbon cleanup.

It is inevitable that carbon deposits will still come, and eventually we still have to wash them. There are many places where carbon deposits are generated, lubrication systems, fuel injectors, intake manifolds and throttle valves, there will be everywhere, so we need to clean the throttle and intake tract first, remove the throttle, you can clearly see the severity of carbon deposits, clean it with a professional cleaning agent, and then wipe it clean with a rag, as for the cleaning of carbon deposits in the engine cylinder, you must remove the cylinder head, timing belt, etc. to have a fuel cleaning additive called clean fuel additive, Generally, when the car is being maintained, the filling measurement is higher than that of the maintenance type of fuel additives, and the effect is better.

First of all, clean the throttle and intake tract, remove the throttle, you can clearly see the severity of carbon deposits, clean with professional cleaning agents, and then wipe clean with rags, as for the cleaning of carbon deposits in the engine cylinder, you must remove the cylinder head, timing belt, etc., so this kind of equipment is not very high in everyone's mouth. But it does not mean that all anti-carbon and fuel-saving equipment are ineffective, such as Yunke Jinba automobile anti-carbon and fuel-saving device, without causing any damage to the car, the carbon prevention rate is truly 90%.

If the carbon deposition increases, the oil should be changed regularly, and the vehicle is most likely to produce carbon deposition when the air conditioner is turned on when it is parked, or when it is parked, so the vehicle should be turned off and parked when it stops driving.

Use car cleaners to reduce the formation of carbon deposits in your car.

The formation of automobile carbon deposits is due to some impurities in gasoline, and if you use gasoline with a relatively high cleanliness, the formation of automobile carbon deposits will be less. If some car cleaners are used, they can activate the carbon deposits that form on the metal surface. Develop good driving habits and warm up the vehicle before each start, which can also reduce carbon deposits.

If the car has too much carbon, you need to go to a professional auto repair shop for treatment. In the process of cleaning up carbon deposits, the engine block must not contain debris.

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 hole is very direct and rude, but it is generally sent to the 4S store for disassembly, the dismantling 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, when the cleaning agent is discharged into the air intake, the carbon deposit is diluted and softened into a slurry, and then burned and discharged from the cylinder. 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.

The residue of substances in the fuel injector, throttle, oil pipeline, spark plug, cylinder head, inner wall and other parts caused by the insufficient combustion of gasoline in the cylinder, and then the black gum produced under 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 up for a long time, it will only cause the operation of the whole vehicle, so that the internal channel of the engine is blocked by carbon deposit, so that the engine power becomes worse, and the occurrence of fuel consumption, abnormal engine noise, and unstable idle speed occurs, thereby reducing the power of the automobile engine, increasing fuel consumption, and the combustion rate is 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.

It is more troublesome to clean the throttle, remove the intake manifold for cleaning, close the intake valve and wash the carbon deposits on the valve.

The cleaning method is to thoroughly clean the inside of the engine by using the walnut shell broken by high-pressure gas mixture, and the powerful gas mixture particles can clean the engine as bright as new, and the walnut chitin is soft and does not damage the metal, which is the most effective way to clean up carbon deposits at present. The daily carbon deposition cleaning of oil roads uses a set of clean fuel treasures every 10,000 kilometers, and the effect is also significant.

Fill with high-quality gasoline. It should be noted that a high grade does not equal high quality, and the label only represents the octane number of the oil, not the quality and cleanliness. Adding high-quality gasoline cleaners to gasoline can effectively prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon particles and slowly remove them, so as to protect the engine from damage.

High speed cleaning, the principle is to increase and maintain a high enough intake and exhaust pressure through the high speed operation of the engine, this way can only clean up the carbon deposits on the surface of the cylinder block, and has no effect on the high viscous carbon deposits attached to the surface of the cylinder block, which is equivalent to wiping the stove with a feather duster, and can only remove the floating ash.

Run more at high speeds and try to increase the shift speed of the handstop car. The purpose of running more high-speed is to use the scouring effect of the air flow on the intake tract to prevent carbon deposits. ‍‍

Special cleaning agent for hanging bottles has a certain positive effect, but the negative effect is greater. The special cleaning agent or hanging bottle can decompose the oil sludge and rely on a very small impact force to melt the carbon and flush it out, which can indeed clean up a part, but the oil sludge washed out may also block the three-way catalysis twice, which is counterproductive.

The fuel injector is responsible for atomizing the fuel, and the carbon deposit of the fuel injector is nothing more than two kinds: one is to directly disassemble and clean; The other is to add fuel cleaner. ‍‍

When the car is cool and hot, the idle time is too long, the engine reaches normal temperature for a longer time, and the gasoline is sprayed on the back of the valve and the evaporation rate is slow, which also creates carbon deposits. Generally, the EFI car, the cool car, and the hot car can be driven on the road in about 2 minutes. At the same time, when driving at idle speed, the air flow into the engine is small, so the scouring effect on carbon deposits becomes weak, which will promote the deposition of carbon deposits.

Regularly cleaning and cleaning carbon deposits is a good habit of car owners, not only responsible for their own cars, but also responsible for their own safety. Here I would like to remind everyone that cleaning carbon deposits must go to professional institutions such as 4S shops and professional car repair and maintenance factories, and do not go to roadside stalls to wash indiscriminately, it is very troublesome to wash it.

Don't listen to those who play with the pen, the best way to clean is to disassemble the engine, soak and clean The premise is that your car is at least l0km later....

There are tools and solvents for cleaning fuel injectors, throttles, and carbon deposits in cylinders, as well as those that are available for a fee. Just bill and pay.
