How many kilometers do you need to clean carbon deposits when you run at high speed?

How does carbon deposition come about?

Carbon deposition refers to the colloidal substance similar to oil sludge produced by fuel and oil vapor that escapes into the combustion chamber when it cannot be completely burned, and these substances adhere to almost any part of the engine room, including intake and exhaust valves, spark plugs, fuel injectors, piston tops, etc., after continuous accumulation, coupled with the action of repeated high temperatures of the engine, and finally form carbon deposits similar to coal.

How to judge the organic carbon of a car? When the car has the following conditions, it can be judged that the carbon deposition of the car is more serious:

1. It is not easy to start when the cold car is ignited many times, and it is normal when the car is hot;

2. The engine idle speed is unstable, and the speed is high and low;

3. The driving feeling is weak and stuffy, especially when overtaking, and the speed response is slow, which is very different from the new car;

4. The exhaust of the car is pungent and the emission exceeds the standard;

5. The fuel consumption of the car has increased a lot compared with before.

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.

It depends on the extent of accumulation, long-term continuous high speed is able to clear some carbon deposits, running at high speed is not necessarily, listening to the old driver said that it is effective, it is recommended to use what carbon is invincible or something, it is said that the effect of carbon deposit is good.

Carbon deposits cannot be removed at high speeds.

In fact, carbon deposition is very simple, it is the sediment left by insufficient combustion of gasoline, and these substances accumulate in the combustion chamber, throttle and other places for a long time, which is what we call carbon deposition.

The generation of carbon deposits is mostly due to the long stop-and-go or idle time of the car, so if you often maintain a high speed, it is indeed not easy to produce carbon deposits, but it is not easy to produce does not mean that it is not generated, and it is normal for the engine to have carbon deposits.

"Pull high-speed" is not easy to produce carbon deposits, but for vehicles that have produced carbon deposits, relying on "pulling high-speed" alone does not have substantial help, the most effective way is to clean the throttle, air intake and other parts, so as to remove carbon deposits most thoroughly.

Can a car run at high speed to clean up carbon deposits? Why?

Normal high-speed driving cannot clean up carbon deposits, but only allows your car to produce less carbon deposits than when driving in urban areas, which just plays a role in suppressing carbon deposits. The real effective way to clean up carbon deposits is at high speeds, and the amount that can be cleaned up according to the mileage is not too much. See the analysis below for the specific reasons:

1. Will there be carbon deposits in the car? I have already talked about the high bend last time, and I would like to reiterate here that there are generally the following types of carbon deposits in vehicles. No matter how long you run at high speeds, carbon deposits elsewhere won't clean well, only carbon deposits in the combustion chamber (carbon deposits on the top of the pistons) do.

2. Why can we only clean up the carbon deposits in the combustion chamber? Personally, I disagree with the online statement that the remaining carbon deposits from the internal parts of the engine are washed away by the intake air. Here's why:

1。Carbon deposits are not dust on the table that can be removed with a blow of the wind; 2.Carbon deposits contain a certain amount of oil, especially the carbon deposits formed by some oil sludge, which are very stubborn; 3.

Carbon deposits are not dry objects like dust. There is a certain amount of oil in the carbon deposit, and it is almost impossible to clean it by relying on the air intake alone. Therefore, it is not feasible to remove carbon deposits by air intake.

It is well known that the formation of finger carbon deposits is due to the incomplete combustion of mixed gases. So why do I say that the carbon deposits in the combustion chamber can be cleaned up? That's because the temperature and the rapid movement of the piston can play a role in high-temperature combustion without the formation of stubborn carbon deposits (cylinders) on top of the piston.

According to the "Formation Mechanism of Internal Combustion Engine and Thermal Carbon Deposition", the temperature of carbon deposition is between 195 and 290, and experiments have proved that carbon deposition is most likely to occur at 200. The reason: at this particular temperature, the carbon produced by incomplete combustion will chemically react with the metal of the cylinder wall, and the carbon will stick very firmly to the cylinder wall, forming what we call carbon deposits.

In the article "The Effect of Piston Temperature Rise on the Growth of Carbon Deposition in the Combustion Chamber", it is mentioned that once the combustion chamber temperature of the engine reaches 325, part of the carbon deposition will be burned and stripped due to the high temperature, so the cleaning effect can be achieved at high speed. But the higher the speed, the easier it is to clean up the carbon deposits. Each car has an economical speed range.

Generally, the speed of family cars is 2000-4000 rpm. After exceeding this speed, the temperature will not meet the requirements, and it is more likely to produce carbon deposits, and it will also wear out and start the boring machine. 3. How many kilometers can I drive at high speed to effectively clean up carbon deposits?

I really can't do this kilometer, because the situation of each car is different, and the carbon deposits formed are also different. But if we clearly feel that the fuel consumption is reduced at a high speed, it proves that the kilometers you are running at high speed are effective.

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 under the repeated high temperature action of the engine is called carbon accumulation.

One of the reasons for carbon accumulation 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:

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 don't 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, 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 has always been a misconception that high-speed driving can remove carbon deposits. If you've looked at the carbon deposits in the combustion chamber and other parts of the actual engine, you'll understand why this claim isn't credible. In fact, high-speed vehicles can only reduce carbon production, but cannot eliminate existing carbon accumulation.

First of all, because most owners rarely have the opportunity to contact the actual situation of early land carbon accumulation inside the engine, of course, some people in the engine intake and exhaust airflow speed is fast when the vehicle is driving at high speed, and the pressure is also large, and the use of the force to make the engine internal carbon deposit collision, this principle has a certain reason, but we ignore a problem. Why? It is because if you pay attention to the engine tachometer when driving at high speed, in fact, the engine speed is about 2000-3000 when driving at 120 kilometers, which is not very high.

One might say that this allows for low speeds and engine speeds of 4000 to 5000 rpm, but there is no real need to do so. But it can't be said that frequent high-speed driving doesn't help reduce carbon deposits. It's just that carbon production can be delayed.

There is no doubt that since the engine is almost always in optimal combustion condition at high speeds, the probability of carbon build-up will be significantly lower than when driving frequently on congested roads in urban areas. Secondly, in the case of the engine's carbon buildup, its formation is caused by a mixture of dust that enters the engine (the air parts are not able to completely filter very fine dust), impurities in the fuel, and oil vapors. The combustion condition of the engine will be a little worse These carbon buildups, especially those in the combustion chamber, have developed a strong adhesion through long-term high-temperature baking and high-pressure pressing, so we want to remove these carbon deposits not through the air flow.

In order to remove these carbon deposits, unless special chemicals and equipment are used, they can only be cleaned in passing when carrying out the decomposition maintenance of the first opening machine. However, this cleaning also requires the use of a special cleaning solution and an ultrasonic cleaner. This cleaning method is mainly realized by using the alkaline components of the cleaning solution under high temperature and ultrasonic high-frequency vibrator, and completely immersion, so that the carbon deposits in stubborn and very hidden places can be completely removed.

Finally, after understanding the above, I believe that the method of cleaning up carbon accumulation by driving at high speeds is still effective. I hope mine is helpful to you. The above is a personal opinion, welcome to comment and follow Like**.

The car has brought great convenience to people's lives, and now almost every household has bought a vehicle, and it is not very expensive, and most families can accept it. With a car, you finally don't have to crowd the bus and the subway anymore, and you can go at any time when you go out to play. On the way to and from school, you can also drive your favorite car without worrying about your child being late.

Especially in windy and rainy weather, if you don't have a car, you will worry about getting your child's clothes wet and causing your child to get sick. <>

Many families bought carsThis can be avoided by driving a car, which enhances the happiness of the family. After buying a car, you can go wherever you want to go, so you don't have to rush anymore. When driving a car, many people don't know how many kilometers the vehicle can run at high speed to clean up carbon deposits?

In fact, the generation of carbon deposits in vehicles depends entirely on the size of the air-fuel ratio, and carbon deposits will be produced when the fuel and engine oil of the car are not completely burned. Vehicles are generating carbon deposits all the time, whether they are running on urban roads or highways. <>

The car has brought great convenience to life, and even when the manufacturer has just produced a new car, as long as the vehicle is ignited for less than ten seconds, carbon deposits may form in the combustion chamber. When the vehicle is at different speeds and in different gears, the effect of carbon deposition cleaning is also different. Many people say that their cars feel lighter than before after running at high speeds, because the carbon deposits have been cleaned up, and many people think so.

How many kilometers can running at high speed play a role in cleaning up carbon deposits? I am convinced of this point of view, and I will promote this point of view, and after a long time, many people feel that it can play a role in cleaning up carbon deposits when running at high speeds. In fact, this statement is not rigorous, carbon deposits do not exist in the engine in the form of dust, and the carbon deposits formed for a long time are in the form of sludge that are stuck in the engine, even if the speed of the vehicle is high, it is unlikely to blow away the carbon deposits of the sludge.

Generally, after running 50,000 to 60,000 kilometers, you can go to a professional store to clean the carbon deposits. It can also play a corresponding role.

Personally, I suggest that you can clean up the carbon deposits when you run 5 or 6 kilometers, but it also depends on the model, and some cars have carbon deposits when they run 20,000 kilometers, so the 40,000 or so must be cleaned up.

It is about 50,000 to 60,000 kilometers, so the low-carbon situation of the vehicle is more serious, so it must be cleaned up in time at this time.
