How to clean up the carbon deposits of automobiles most thoroughly?

Flushing of high-grade gasoline: Because the gasoline with a higher grade is relatively low-grade and has a high octane number, it burns completely and cleanly, and the likelihood of carbon deposits is much lower. Residual carbon deposits can be effectively washed out by high-grade gasoline.

For example, if your car is filled with 92 gasoline, then you can fill one or two tanks of 95 gasoline if you feel that there is carbon deposit. Running at high speeds: Because running at high speeds can use the scouring effect of air flow on the air intake tract to prevent carbon deposits.

In addition, increasing the speed of shifting gears is also similar to running at high speed, turning the original gear shift at 2000 into 2500 conversion, which can not only effectively prevent the generation of carbon deposits, but also improve the dynamics of the car, and also avoid the detonation caused by too low shift speed and protect the engine.

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.

Carbon deposits are deposits that occur when fuel and lubricant are mixed with blow-by gas and are incompletely combusted.

The main components are hydroxy acid, asphaltene, tar, etc., and the formation of deposits is directly related to the "fuel" and "lubricating oil" of automobiles.

If you don't pay attention to the oil and driving habits for a long time, the wax and gum in the gasoline will accumulate thicker and thicker, and carbon deposits will be formed when it hardens after repeated heating. If the engine burns oil, or if the gasoline is of poor quality and has more impurities, the valve carbon deposits are more serious and form faster.

1. When carbon deposits adhere to the intake and exhaust valves, the intake and exhaust valves are not closed tightly and the air leaks, and the pressure in the engine cylinder drops, which directly results in the difficulty of engine activation and shaking under idle conditions; At the same time, it affects the section of the mixture into the combustion chamber, and the carbon deposition can adsorb a certain amount of the mixture, thereby reducing the engine power.

2. When the carbon deposit adheres to the cylinder and piston top, it will reduce the volume (space) of the combustion chamber and increase the cylinder compression ratio, and when the compression ratio is too high, it will cause the engine to burn prematurely (engine knocking) and reduce the power generation.

3. When the carbon deposits adhere to the spark plug, it affects the quality of the spark; Not even a jumper.

4. When carbon deposits are formed between the piston rings, it will easily jam the piston rings, causing oil burning and straining the cylinder wall.

5. When carbon deposits adhere to the oxygen sensor, the oxygen sensor cannot correctly perceive the exhaust gas condition and cannot correctly adjust the air-fuel ratio, so that the engine exhaust gas exceeds the standard.

6. When carbon deposition is formed inside the intake manifold, it becomes rough inside, which affects the formation and concentration of combustible mixture. Carbon deposits are so harmful that they must be removed immediately.

If the carbon deposit is not cleaned for a long time, the operation of the whole vehicle will be caused, and the internal channel of the engine will be blocked by carbon deposits, so that the engine power will deteriorate, thereby reducing the power of the automobile engine, increasing fuel consumption, and the combustion rate will 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.

After the car has been used for a long time, remember to remove carbon deposits.

The most dismantled and washed engine is the most thorough carbon deposition cleaning of the car. Dismantling and washing the engine is the most expensive and time-consuming method to clean. But as a last resort, most people will not do this "major surgery" because the cost is too high and it hurts the muscles and bones.

Removing and washing the engine is the most effective way to remove carbon deposits, not only from the cylinders, but also from the valves and pistons. But the cost is too high and it takes a long time. Nowadays, many car owners will follow the advice of maintenance technicians and choose to "play the hanging bottle" first, and then disassemble and wash the engine if the effect is not good.

However, after "dismantling and washing the engine", fuel consumption did not decrease but increased. Dismantling the engine once is a damage to the car, which will be directly reflected in fuel consumption.

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.

At high speeds, the vehicle can take advantage of fluid washout and high fuel efficiency to reduce carbon deposits in the engine. 2. Use fuel treasure: Fuel treasure is added to gasoline, and as the gasoline enters the engine block together, fuel treasure can soften the carbon deposit, and then it can be removed.

However, it requires a lot of fuel treasure, and the effect is not good.

There are two ways to clean carbon deposits, non-dismantling cleaning and dismantling cleaning, the most suitable method at present is to dismantle and clean, that is, to clean in the driving, with the cleaning agent of the general fuel detergent in the fuel tank, after normal driving, through the driving discharge of harmful substances and carbon deposits on the oil road. Let me show you the renderings of my car's car after 1,400 kilometers after being cleaned with Scoop Fuel Cleaner. Can be used as a reference.

Pay attention to the date in the lower right corner, which was taken twice before and after, and the dashboard is the number of kilometers twice.

After the car has been used for a long time, remember to remove carbon deposits.

Real shot: The 40-year-old driver actually cleans up the carbon deposits of the car, the operation is simple and easy to use, and he deserves to be an expert.

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.

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.

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 non-corrosive, will not clog ternary, and have a relatively high level of safety.
