Do I need to clean up carbon deposits for the first time of car insurance?

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.

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.

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.

One of the causes of carbon deposition is that the fuel burns insufficiently, which adheres to various parts of the engine and forms carbon deposits over time. 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 not corrosive, can clean the whole oil circuit, fuel tank impurities, fuel tank moisture, high-pressure oil pump, built-in gasoline filter, fuel injector, piston top, intake valve, exhaust valve, will not clog ternary, and the safety is relatively high.

In fact, any vehicle has carbon deposits, and a slight carbon deposit has no effect on the vehicle. Only if there is too much abnormal carbon deposit, it needs to be treated, but the method is not to deal with carbon deposits, but to find the reason for the abnormal increase in carbon deposits.

It is very necessary to wash the carbon deposits of the car. More carbon deposition will change the original structural parameters of the engine, reduce engine power and increase fuel consumption; In severe cases, it will also cause engine knocking, acceleration noise, and damage to the piston and crankshaft. Benefits of Carbon Deposition Cleaning:

1. Enhance the power of the car;

2. Save fuel consumption;

3. Reduce the detonation point;

4. Promote environmental maintenance;

5. Extend the life of the engine;

6. Strengthen the accuracy of braking.

Depending on the situation, the cars driving in the city should be cleaned up once for 2-30,000 kilometers, and the cars driving on the highway should be cleaned up for 3-40,000 kilometers.

The owner can check the carbon deposit according to the maintenance manual of the bureau vehicle, the cycle of replacing the spark plug, and then carry out the necessary carbon deposit. The general maintenance manual recommends that the spark plug be replaced for 2-30,000 kilometers, so it is more appropriate to clean up the engine carbon deposits when the spark plug is replaced at 2-30,000 kilometers.

That is to say, on the premise of not dismantling the engine, special equipment is used to remove carbon deposits from the parts of the vehicle that are prone to carbon deposits, such as air intakes, valves, and oil circuits.

1. Remove the engine trim cover, remove the throttle and clean it with carburetor cleaner, wipe it dry with a cotton cloth and install it;

2. Open the oil cap, pour the whole tank of detergent, cover the oil cap, and turn off the ignition after idling for ten minutes;

3. Pour the detergent of the air intake system into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use the vacuum to suck the detergent into the air inlet to achieve the purpose of cleaning.

Here's how to tell if a car has carbon deposits:

1. Check the usage of oil, the growth rate continues to rise, indicating that carbon deposits have been formed on the engine;

2. According to the mileage, the higher the mileage of the car, the more carbon will be accumulated;

3. Replace the gasoline with a higher grade, and the power has been improved, indicating that the engine has more carbon deposits.

1. The most common is to disassemble the throttle, clean the front and back of the throttle with a carburetor, and dry it with a cotton cloth. Generally, it is recommended to clean the lower throttle for a year or 20,000 kilometers, of course, different models will have different cleaning cycles, we can do it according to the maintenance manual.

2. Carbon deposition cleaning inside the engine, we can do it before we want to change the oil to a new one. Open the oil cap, add detergent, mix with old oil, and idle for about 10 minutes. You can buy the detergent by yourself, the operation is very simple, and you can operate it yourself.

3. To clean the air intake system, buy a bottle of air intake system cleaner, pour it into the liquid storage tank of the special cleaning equipment, connect it to the air intake system, and use the vacuum to suck the detergent into the air intake road to achieve the purpose of cleaning. Cleaning the carbon deposits in the intake system mainly refers to cleaning the carbon deposits inside the intake tract and intake manifold. The purpose is to remove carbon deposits from the intake system, increase intake flow and speed, and reduce engine shake and idle instability.

There is a way to prevent carbon deposition, first, run at high speed, add fuel treasure the next day, prevent carbon deposition, if necessary, every 2 to 30,000 kilometers, go to the car repair shop for bottle cleaning, so as to better protect your car.

The necessity of cleaning up carbon deposits in cars.

If you are a turbocharged engine, it is recommended to add additives in accordance with the manufacturer's regulations, if it is naturally aspirated, don't care too much, just run high speed every year, not as serious as the 4S store said, are fooling your consumption, the current engine technology is very mature, rest assured to drive. Chances are you can ask the taxi drivers, none of them regularly clean up the carbon deposits!

Cleaning up carbon deposits is very simple, and if it is mild, it can be solved by adding fuel additives. Each bottle is not expensive.

Summary. It is recommended that carbon deposition cleaning is based on the time of use, when the vehicle reaches 100,000 kilometers or 6 years of driving, the carbon deposition is cleaned to prolong the service life of the engine.

Hello, I'm sorry you have the necessary questions. Kiss.

Carbon deposition is mainly due to the fact that gasoline cannot be burned 100% completely, and the remaining impurities adhere to the intake valve or combustion chamber to form carbon deposits. According to this reason, if low-quality gasoline is added for a long time, the accumulation rate of carbon deposits will also be faster.

The power decreases, fuel consumption increases, and the combustion efficiency is lower than that of the new car. Moreover, when the carbon deposit is serious, it will also cause problems such as low idle speed, idle shivering, and under special circumstances, it may also lead to flameout. So it's a terrible thing that carbon deposits have become serious.

Therefore, it is still necessary to clean up.

It is recommended that carbon deposition cleaning is based on the time of use, when the vehicle reaches 100,000 kilometers or 6 years of driving, the carbon deposition is cleaned to prolong the service life of the engine.

It is necessary for the car to clean the carbon deposit, and the harm caused by the carbon deposit in the engine: 1. The power of the engine will decrease after the carbon deposit inside the engine, and the car will not be as strong as before when driving, and there is a feeling that the engine power and economy will decline, which is not only difficult to drive and consume fuel, but also has a great impact on automobile emissions; 2. After the formation of carbon deposits at the intake and exhaust of the engine, especially at the exhaust valve, it is easy to cause "sub-valves". Because the carbon deposits attached to the valve will prevent the exhaust valve from dissipating heat, although the exhaust valve is treated by a special process, it cannot be avoided when the carbon deposit is too high and the temperature is too high to dissipate heat; 3. Carbon deposition is generated at the piston head, which is easy to form multiple ignition points when the engine is burning, so that the combustion in the cylinder is insufficient and causes deflagration, and the power of the engine decreases at the same time, which may cause the cylinder to be pulled in serious cases; 4. For direct injection engines, the generation of carbon deposits in the cylinder can easily cause the fuel injector to be blocked, and there are countless such cases.

The fuel injector is clogged, the engine shakes, and the acceleration is weak.
