How much do you know about car maintenance? Is it necessary to clean up carbon deposits in automobil

Due to the combustion of the car in the process of use, it is essential to produce carbon deposits, so is it necessary to clean up the carbon deposits of the car?

When it comes to whether automobile carbon deposits need to be cleaned up, we must first understand what automobile carbon deposits are and what are the hazards of automobile carbon deposits.

We all know that gasoline contains many different components, and automobile carbon deposition is a kind of coke substance produced by the incomplete combustion of unsaturated olefins and gum in gasoline during the working process of automobile engine, and the main parts of carbon deposition are in the valve, combustion chamber and intake pipe.

Now that we understand the generation of carbon deposits, let's talk about the dangers of carbon deposits. Carbon deposition in the valve and combustion chamber may cause undesirable phenomena such as difficulty in starting, unstable idling, decreased power, excessive exhaust gas, and increased fuel consumption; Carbon deposition in the intake pipe may cause the throttle valve to not be completely closed, low idle speed, oil collection and vehicle extinguishment, exhaust gas exceeding the standard, and increased fuel consumption.

How to judge the carbon deposition of automobiles? The intake tube can be observed by removing the throttle valve, and the valve combustion chamber can be observed with an endoscope.

So how should car carbon deposits be cleaned up? In fact, cleaning up the car's carbon deposits mainly cleans the air intake tract and throttle, these two parts can be disassembled and cleaned, and the carbon deposits in the valve combustion chamber are not recommended to be disassembled and cleaned, the engine airtightness is very high, and each disassembly will have an impact on the airtightness of the engine, thereby affecting the life of the engine and causing the power of the engine to decline.

So don't you need to deal with the carbon deposits in the valve combustion chamber? No, the main prevention of carbon deposition in the valve combustion chamber is mainly to prevent it, and the main prevention methods are: 1. Reduce idle driving, thereby reducing the time of incomplete combustion of the engine; 2. Driving at high speed from time to time, high speed can increase the amount of fuel injection from the fuel injector and increase the air inflow, which will wash away a part of the carbon deposits that have not yet solidified, so it is reasonable to say that the carbon deposits are cleared at high speed; 3 Regular use of additives can also be effective in reducing carbon deposits.

The vehicle is our partner, it is very important to maintain the car with the car, and only by taking good care of our partners can it serve us better.

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.

Carbon deposits in the internal gas system and carbon deposits in the exhaust system. There is also a throttle, so in the case of this opportunity, I will first tell the majority of friends, we set up a carbon deposit is a normal state, as long as the combustion engine works, he will definitely produce an altar, even if my oil will be consumed, through the exhaust pipe to re-participate in combustion, piston ring scraping is not clean, etc., the oil will burn when the flash point exceeds the flash point at high temperature, and the combustion produces solid and viscous impurities attached to the combustion chamber.

With the passage of time, the carbon deposition of the throttle flap will be more and more to affect the intake efficiency, take the idle speed as an analogy, the normal throttle idle without carbon deposition when the flap opening is 6%, and the idle speed of 700 rpm is just at the target speed. However, there is a lot of carbon deposits, and there are many parts of the car that generate carbon deposits in a strict sense, and the time and method of cleaning are different, generally speaking, carbon deposits will be generated more in the lubrication system, air intake system and fuel system, we will take a look at how long these places need to clean up the carbon deposits. Carbon is a flood beast, and it's common practice to clean up carbon deposits regularly or use fuel cleaners.

In fact, in the whole life cycle of the normal engine, it is not necessary to clean the carbon deposits, don't believe it, so many long-term engine operation tests, when there is a heavy one, the engine will idle unstable, or even stall, fuel consumption will increase, and it will also cause poor acceleration of the vehicle. In fact, engine carbon deposits are closely related to air quality, fuel quality, driving habits, and vehicle engine performance.

If it is a naturally aspirated model, within 100,000 kilometers, there will be no big problem if you don't clean it, and occasionally clean the throttle. That's it. However, if there are parts of the fuel system of your intake system that are broken, it is necessary to pay attention to it, because after the ignition system is discharged, check whether the fuel injector is blocked, and the carbon deposit will seriously affect the normal atomization of the spark plug.

There is no specific number of kilometers of the car that should be cleaned up of carbon deposits, carbon removal is not a routine maintenance item, strictly speaking, it can be regarded as a failure, and there are no symptoms that do not need to be cleaned up.

The symptoms of serious carbon deposition are nothing more than idle shaking, increased fuel consumption, decreased power, serious exhaust odor, etc., but it is not only more carbon deposition that will lead to the emergence of these phenomena, the general family car can be inspected once in about 3 years, and the steps are as follows:

If the above phenomenon occurs, first check whether the spark plug flashover is normal, whether the cylinder line is leaking, and the ignition system failure will cause insufficient combustion and affect the normal driving.

After the ignition system is discharged, check whether the fuel injector is blocked, and the carbon deposition will seriously affect the normal atomization of the spark plug, such as oil dripping or serious wet wall problems, it will also cause insufficient combustion, resulting in power attenuation and shaking.

After the ignition system and oil circuit are found to be eliminated in time, if the engine is running normally and the fuel consumption is normal, it means that there is no problem with the engine and the intake and exhaust system.

The time to clean up carbon deposits is related to your driving habits and driving conditions, rather than simply saying a fixed time. Simply add a bottle of carbon deposition to the engine oil after changing the oil, and then start the engine to turn for a while and then change the oil, so as to achieve the purpose of cleaning up the carbon deposit.

Under normal circumstances, it is more appropriate to clean up in about three months to half a year, and when cleaning, you must turn on the locomotive feeling of the engine, and then use a rag to get some dust out, if you really can't clean it, you can go to a professional 4S shop for maintenance.

The car needs to be cleaned up after half a year of driving, and our family goes to the 4S store every time to clean up the carbon deposit, because it is really too troublesome to clean it up by yourself.

In about three months, you have to properly maintain and clean the car, so that every aspect of the car will not be seriously damaged. You can go to some car repair factories to clean, or you can learn to clean at home.

It is best to clean the cars driving in the city once every 2-30,000 kilometers, and the cars driving on the highway once every 3-40,000 kilometers.

Carbon deposition includes two concepts:

1. One concept is the carbon deposition of the engine: a coke-like substance produced by the unsaturated olefins and gum in the fuel at high temperature during the working process of the engine.

2. The second concept is carbon deposition in EDM, which should be avoided as much as possible in EDM, especially in precision mold processing.

Hello, the car cleans up carbon deposits, and it is recommended that the throttle be cleaned once every 10,000 kilometers. The fuel system is cleaned once every 20,000 kilometers, and I hope it can be used for reference.

About 30,000 cars can use Chevron special strength additives, and old cars need to find a professional repair shop, and it is easy to have problems when cleaning them themselves.

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.

Methods for removing carbon deposits.

1.The whole machine cleans the cylinder.

In a general garage, the inside of the cylinder head can be cleaned and carbon deposits removed without disassembling the engine.

2.Use a fuel cleaner.

Fuel cleaners purchased at gas stations claim to remove impurities from the oil circuit, and also contain carbon deposits at the fuel injectors. There are also different theories about the effect of this approach and whether it will bring other consequences, and it is recommended that professional departments do corresponding experimental research.

3.Cleaning engine parts.

When overhauling an engine, you can use detergents, ultrasonics, etc. to remove carbon deposits on parts. The advantage is that the carbon deposits are cleaned completely and thoroughly, but the disadvantage is that the engine needs to be disassembled, which is labor-intensive and time-consuming, and may also cause problems due to negligence in the reassembly process. If you can't be sure that the engine has significant carbon deposits, don't do it lightly.

Driving the engine the right way and maintaining it regularly can reduce the formation of carbon deposits in the engine. Be sure to take care of your vehicle when driving, if you drive in a bad environment for a long time, it will only cause the scrapping period of the vehicle to be premature.

It is recommended to carry out demolition-free carbon deposition cleaning every 4-60,000 kilometers. Because carbon deposition cleaning is a more professional problem, it is recommended to go to a 4S shop or car repair shop for it.

It is recommended that cars clean up carbon deposits every 40,000 to 60,000 kilometers without dismantling them. It is necessary to choose your own engine type to choose the appropriate additives, PEA for direct injection, PIBA for intake manifold injection.

Whether or not it is necessary to remove lead and carbon deposits can be decided according to the use of the vehicle and the inspection of the air intake pipe. When maintaining a vehicle, it is recommended to remove carbon deposits, which is not mandatory and can be considered separately in conjunction with vehicle use and budget. If the idle speed is stable, or there is no Huai aware of the detonation, the power decreases, the fuel consumption increases, etc.

There is no need to remove carbon deposits for the time being; Carbon deposits are unavoidable during vehicle use. There is no need to worry about this carbon deposit. For example, frequent short distances, moderate high-speed driving, or the appropriate use of clean fuel additives can slow carbon deposits.

When the vehicle is driving and the mileage is large and the carbon deposits are serious, it is recommended to disassemble the throttle valves, intake manifolds and other accessories, and then remove the carbon deposits in the above parts;
