What are the ways to clean up carbon deposits, and the best way to clean up carbon deposits

Here are two specific methods of carbon deposition removal – using fuel additives and manual dismantling.

Fuel added cleaning agent.

There are many brands of fuel added cleaners on the market, such as Lipto, Willis and so on. The fuel with detergent is added to the oil supply system, and the chemical components in it are used to decompose the gum attached to the system, and automatically remove the carbon deposits inside the valves and engine cylinder walls, so as to avoid the accumulation of gum and impurities to form carbon deposits. Although this method is convenient, but a certain negative effect, on the one hand, the impurities and gum that are decomposed will not be eliminated, it will remain inside the gasoline filter, if the gum precipitation is more, the filter will lose its effect, so it is necessary to replace the gasoline grid in time; On the other hand, although the chemical composition can decompose and remove colloidal impurities, it has a corrosive effect on other parts of the fuel system, such as the oil supply pipeline may accelerate aging or be seriously corroded.

It is also a reminder that you should be careful not to use too mundane and add detergents.

Manual cleaning. The advantage of manual cleaning is that it is unlikely to lead to any replacement of the filter or oil pipe, how to choose the corresponding method for the severity of carbon deposition, such as valve carbon deposition, as long as the intake manifold is disassembled, and the use of ordinary detergent or rag scrubbing can be; For the carbon deposits attached to the engine cylinder wall, if the engine is not disassembled, it is generally difficult to clean, so it is relatively complicated, and the disassembled engine may affect the power performance and sealing of the engine, resulting in the engine not working properly or may damage the engine. If there is a lot of carbon deposits inside the cylinder wall, and the fuel can not be removed by adding detergent, it is best to go to the 4S point to ask professional technology to solve it.

Either way, the ultimate goal is to remove the carbon deposits that exist in the engine's internal systems and extend the life of the engine.

The reason for carbon deposition: determined by the control characteristics of the electric injection engine, the cylinder is first injected and then ignited every time it works, and the ignition is cut off immediately when we extinguish the engine, but the gasoline sprayed out by this work cycle can not be **, after the unburned gasoline in the cylinder volatilizes, the remaining glue and wax will be deposited on the cylinder wall and valve, which can only be attached to the intake valve and the combustion chamber wall. The method of removing carbon deposits, one is that the carbon deposits are not too serious, and the non-dismantling cleaning method is adopted, "The method is simple and labor-saving, and it only needs to be used in the correct way."

However, for engines with serious carbon deposits, this method is inadequate and cannot achieve the purpose of complete cleaning. After the disassembly and cleaning, if the engine performance is still bad, then you should pay attention to it, it may be caused by too much carbon deposits in the valve and cylinder, then you have to use the method of disassembling the engine to solve it. Valve carbon deposits can be easily cleaned by removing the intake manifold and soaking it by hand or with cleaning chemicals.

As for the cleaning of carbon deposits in the engine cylinder, it is necessary to "make a big move" and remove the cylinder head and timing belt before cleaning. However, you should still pay attention to the cleaning process. Car carbon deposition cleaning is a very important work, it is generally not recommended to operate by yourself, do a good job of going to the relevant professional place for cleaning, cleaning links are very important, in fact, daily maintenance is also very critical, to minimize the formation of carbon deposition can effectively protect the engine, you not only have to cultivate good driving habits, try not to shift gears at low speed, in this case gasoline combustion will occur inadequate, easy to produce carbon deposits.

Regular cleaning and maintenance is also important.

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 by 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 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 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.

The gasoline additives currently on the market can be broadly divided into four categories:

1.Clean: When the vehicle clearly feels that the fuel supply is not smooth, the carbon deposits in the valve and fuel injector areas are serious, this fuel additive can be appropriately selected.

2.Curing type: The main function of this additive is to inhibit the generation of carbon deposits and ensure the normal operation of valves and fuel injectors.

3.Octane number adjustment: Octane number refers to the knock resistance index of fuel, for example, the octane number of No. 92 gasoline is 92; This fuel additive is mainly used to improve the octane of fuel to a certain extent, improve the quality of oil products, and can play a role in energy saving and emission reduction.

4.Comprehensive type: This additive is a combination of the characteristics of the above three products, and is a relatively advanced fuel additive, such as PNF stock solution.

To sum up, fuel additives do have a role, that is, people take supplements for the same reason, and the effect can be seen after a long time of use instead of two times. Therefore, it is recommended that if you want to use fuel additives, you should insist on long-term use, which is good for reducing the formation of carbon deposits in vehicles.

How should I clean up carbon deposits?

There are many common ways to remove carbon deposits, but it is also necessary to "prescribe the right medicine" below.

1.Clean the throttle and intake tract.

Spray the throttle and intake tract with carburetor cleaner, scrub it, and some don't even remove the throttle, this method has a little effect, but it is very incomplete. The 4S shop may charge 80-100 yuan, in fact, in the repair shop, you don't even need money to do it.

2.Hang the bottle.

In fact, the "hanging bottle" is filled with a cleaning agent that has been atomized under pressure, and the cleaning agent is injected into the air intake, and the carbon deposits in the throttle and fuel injector are "solvent dissolved" reactions, and then the high speed of the engine is used to blow the cleaned carbon deposits out of the engine.

It should be noted that this method expels the cleaned carbon deposits through the exhaust system, but if the carbon deposits are very serious, it will cause blockage or even damage to the three-way catalytic system. Therefore, you still can't be careless when you use this method.

3.Use "detergent".

It is to pour a specific cleaning agent into a machine, spray it into the combustion chamber under pressure by the machine, let the cleaning agent react with the carbon deposit to dissolve, and then pump out the waste liquid.

It is also important to note that if the carbon deposits are very severe, there is a high risk of damage to the combustion chamber if the large carbon deposits that fall cannot be completely extracted.

4.Use fuel additives.

Clean fuel additives can be used for daily cleaning of carbon deposits. The long-term use of clean fuel additives, although not as thorough as advertised, still has a certain effect, especially for non-direct injection models. However, it still depends on the quality and performance of the cleaning agent used.

5.Dismantling and washing. If your car's carbon deposition phenomenon is more serious, then dismantling and washing is the most effective way to remove carbon deposition, of course, it is relatively troublesome and expensive.

However, you don't need to understand it as an overhaul, in fact, it is to remove the intake manifold, disassemble the engine cylinder head and other parts, and clean the engine. Generally, it is not a problem to find a regular repair shop or 4S shop.

6.Pull high speed.

Theoretically, at high speeds, the engine speed is increased, and the air intake increases, which can wash away a part of the carbon deposit. However, the actual effect is minimal, and it can only be relatively fully combusted, which has the effect of alleviating the aggravation of carbon deposits, and there is no need to deliberately run at high speed in order to clean up carbon deposits.

Due to its working environment and the nature of its work, carbon deposits may be formed on this part. The most common way to clean up the carbon deposits on the throttle valve is to disassemble the throttle valve and then use a carburetor to clean the front and back of the throttle valve, and then use a cotton cloth to wipe off the carbon deposits that have been decomposed. 2. Carbon deposition inside the engine

Carbon deposits inside the engine are mainly reflected in the pistons of the intake and exhaust valves and combustion chambers. The carbon deposits can be cleaned with additives, which are added directly to the tank.

Question: Is Fuel Treasure reliable?

What brand is good.

What brand is good.

Hello answer, I have seen your question and am sorting out the answer, please wait for a while Fuel treasure can remove carbon deposits, but it is difficult to remove some stubborn carbon deposits. Cars suitable for adding fuel treasure are: large displacement cars with complex engine structure and more cylinders; For cars with small displacement engines with high oil requirements; More than 30,000 kilometers of old cars.

Effects of excessive carbon deposition in the combustion chamber:

1. The engine combustion chamber is the worst place in the working environment of the car, which is under high temperature and high pressure for a long time. Inevitably, carbon deposits also occur here, mainly from the pyrolysis of incompletely burned fuel. The carbon particles here are hard and pot-shaped, and in severe cases, they are honeycomb and have a certain thickness;

2. The carbon deposition here will affect the intake vortex, hinder the rate of flame propagation, and lead to a decrease in power, which will lead to engine knocking (commonly known as cylinder knocking), and even excessive pressure leading to combustion chamber breakdown;

3. Slight carbon deposition does not matter much, but carbon deposition in the combustion chamber is an accumulation process from slow to fast, so daily cleaning is very important.

4. It is difficult to start the vehicle in winter, and the engine shakes after starting, and even causes the engine not to start; There will be a lack of acceleration of the vehicle; Idle shaking of hot cars; The phenomenon of blind increase in the oil consumption segment; Every carbon deposit inside the engine will have a bad impact on the normal operation of the engine, and in severe cases, it will cause irreversible damage to the engine piston.

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 with poor combustion width can be seen directly when dismantled and cleaned, 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, soften the carbon deposition and 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.

Same with range hoods. If the wind is stronger, it will be pumped into the pipe or directly connected to the outside, (this is the high speed of the engine). But you have to make this thing every day, and you don't send it to avoid it getting buried in oil and getting dirty!

The most thorough is to use it for a period of time, dismantle it, and wipe it with a pot ball, laundry detergent, dish soap, collar clean, etc. So cleaning up the world's carbon deposits is also the same.
