To clean the carbon deposits in the valve of the inlet valve, which cleaning agent is easy to use, a

Carburetor cleaner is about ten dollars on the market.

It is necessary to clean the carbon deposit of the intake valve, and it can be cleaned once every 20,000-30,000 kilometers.

Do not spray a large area with throttle cleaner to clean the throttle, and then wipe it vigorously, which will cause great damage to the throttle. After cleaning the throttle, it is necessary to use the computer to make a match, so that the computer's control of the throttle valve can be restored to the original state.

The hazards of carbon deposition in the intake valve are as follows:

1. When the carbon deposit adheres 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, and the direct result is that the engine is difficult to activate, and the shaking occurs under idle conditions, and at the same time affects the section of the mixture entering the combustion chamber, and the carbon deposition can adsorb a certain amount of 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.

3. When the carbon adheres to the spark plug, it affects the quality of the spark and even does not catch fire.

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

The cleaning of the intake system is generally carried out for the throttle valve, intake manifold and intake valve, and there are two ways: dismantling and cleaning.

Disassembly and cleaning: The air intake system components will inevitably be damaged during disassembly, or the sealing performance of the system will be affected, and some sealing parts will be damaged and need to be replaced, resulting in increased maintenance costs. The advantage is that if the construction is standardized and the construction is in place, the cleaning effect is more thorough.

Dismantling and cleaning: It has been rising for a long time in the domestic automotive aftermarket, and the most common is the form of "hanging bottles". The advantage is that the damage to the mechanical parts is small, if the special cleaning agent is used, it is harmless to the three-way catalytic system and oxygen sensor of the vehicle, and at the same time, it can be pre-washed for cleaning the stubborn carbon deposits in the combustion chamber, and the cleaning effect can be better when the next step of "fuel system cleaning" is carried out.

Hello, I am helping you sort out the answer to the question, please wait a while Hello, I will help you answer this question, there are probably two major cleaning methods for the cleaning of the air intake system, the first is to clean the air intake system without disassembly, this has a special, the equipment can clean the air intake system, add cleaning liquid directly to the equipment, and then clean the air intake system.

The second situation is to directly disassemble the intake branch pipe for cleaning, this cleaning method has a relatively large amount of engineering, but the cleaning is more thorough.

Ask how to clean the inlet box.

Ask what to clean when you remove it.

How to wash in the absence.

Ask what to clean when you remove it.

Dear, I don't know if you are satisfied with my answer? If you are satisfied, can you give a like, I look forward to continuing to answer for you next time, I wish you all the best!

There are many car owners will find that the car is unable to accelerate after a certain period of time, step on the accelerator hard but the car does not raise the speed, and the fuel consumption has increased, sometimes after ignition it is found that the car shakes very much, especially at idle, in fact, this situation means that the intake system has carbon deposits, in the exhaust valve, intake valve and cylinder edge and other parts have carbon deposits precipitated after combustion, resulting in poor air intake, poor air intake will lead to oil road mixing, oil and gas mixing will be too concentrated and fuel consumption will increase, Although the fuel is consumed, the power is not up to the requirements. Don't panic in this case, you only need to clean the carbon deposit in the air intake system to solve this problem, this is a normal phenomenon, because the vehicle burns gasoline during driving, and the impurities in the gasoline will be adsorbed in the air intake pipe in this process. <>

1. How to clean the carbon deposits in the air intake system?

The carbon deposition cleaning of the intake system is very simple, according to the different degrees of carbon deposition, the cleaning method is also different, if it is only to clean the carbon deposition on the wall of the intake pipeline, and the vehicle itself is in a good state, then you only need to add some fuel treasure or cleaning agent in the fuel tank when refueling, you can clean the intake pipe in the daily driving process, if the carbon deposition on the wall of the intake pipe is more, then you need to remove the intake pipe and use a professional cleaning agent to clean it, and in this process, you can re-clean the throttle valve by the way, Because it is relatively hard, it is not easy to clean, and sometimes it needs to be cleaned with a scraper and other tools, and after cleaning, it needs to be matched with a computer again. <>

2. What should I pay attention to when cleaning the air intake system? <>

The air intake system is a very large mechanism, which not only has an oil circuit, but also a series of parts such as throttle valves, spark plugs, etc., must pay attention to the sequence when cleaning, to avoid scratches, fragile parts must be in strict accordance with the installation standards after cleaning, and the computer needs to be used to detect the values after cleaning, so as not to cause errors during installation and affect the engine work.

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.

You should go to the auto repair shop and ask the auto mechanic to help clean it, because they are more professional.

The throttle valve needs to be cleaned with a special cleaning agent, otherwise it may cause problems such as acceleration fatigue or engine trembling, so what cleaning agent is good for cleaning the throttle?

Use carburetor cleaner to clean, but in fact, the best effect of cleaning the throttle is to use a special cleaning agent, the special cleaning agent can not only clean the impurities in the throttle, the lubricating components contained in the cleaning agent can also lubricate and maintain the parts inside the throttle, among the many special cleaning agent brands, the more famous 3M throttle valve cleaning agent has a better effect.

As the name suggests, this product was born at the beginning of the carburetor to clean the carburetor of the old carburetor, the carburetor cleaner can clean the old impurities of the carburetor products, and its characteristics of quickly cleaning impurities.

As the entrance for air to enter the inside of the car engine, the throttle needs to be cleaned every tens of thousands of kilometers, and it is recommended that you choose a special cleaning agent for cleaning when cleaning, which can not only clean the internal impurities, but also maintain the throttle valve and reduce the failure rate of the throttle.

Disassembly and cleaning throttle method: remove the entire throttle assembly, and then use a special cleaning agent to fully clean and then restore, although this way is more troublesome, but disassembly and cleaning can be cleaned more thoroughly, and the effect is more ideal. However, due to the continuous opening and closing of the throttle valve and the direct wear of the throttle body during the operation of the engine, the two surfaces worn before dismantling can also ensure a tight fit.

If the assembly position is changed after disassembly, it will lead to poor closure and failure.

The correct cleaning method and precautions for the throttle.

The carbon deposition cleaner can choose 3M, BASF or Chevron brand.

Engine carbon deposition cleaning agent has a practical effect, but due to its short retention time in the engine cleaning, coupled with the congenital defects of the no-dismantling cleaning method, it is relatively limited in terms of cleaning effect. The cleaning agent is filled directly into the fuel tank and mixed with the fuel until the vehicle is started.

The cleaning agent will enter the combustion chamber with the fuel, and when the cleaning agent enters the combustion chamber, the carbon deposits inside the engine will be cleaned to a certain extent. The cleaning effect is the best, but due to the heavy workload, time-consuming and labor-intensive, the general 4S store will not provide dismantling and washing services.

Extended Information: The use of carbon deposition cleaners is described below:

For some dirt, the cleaning effect is not large, and it may cause damage later. Due to the large amount of dirt, the cleaning process may lead to oil circuit blockage and poor lubrication, and even tile burning, so it depends on the situation. Of course, there are also benefits to using engine cleaners.

Effectively clean the engine lubrication system and remove the oil film and sludge formed by the old engine oil; Effectively exert the lubricating performance of lubricating oil and enhance the fluidity of engine oil; It neutralizes long-term harmful acids generated inside the engine.

How to clean the carbon deposits on the intake valve? The cleaning method for carbon deposits in the intake valve is as follows:

1. Add the New Year's costume "Fuel Treasure". It's adding detergent to the gasoline stupid, which is the easiest to operate, but it doesn't work well. If it is a bottle before checking the car, it will have some effect. In daily use, the cleaning effect of Fuel Treasure is minimal;

2. "Hang the bottle." "The hanging bottle is similar to the form of a hospital hanging bottle. The cleaning liquid is injected into the valve for better cleaning effect. It doesn't have to take apart the car engine, and it's also a more effective way to clean;

3. Remove the engine and remove the cylinder head. Disassembly and cleaning is definitely the most thorough and direct cleaning method, and the cleaning effect is also the best.
