    Intake valvesCarbon depositsThe cleaning methods and the hazards of carbon deposition are as follows.

    1. Pull the high speed.

    If you're driving a manual transmission.

    If time permits, you can pull the high speed with a lower gear on the highway, and in this way, you can clean up the carbon deposits on the intake valves, and similarly, if it is an automatic transmission.

    The vehicle can also be put into the gearbox.

    Change to manual mode, and use the same method to pull the high speed, usually maintaining about 3000 rpm is enough.

    Because at high speeds, the throttle of the vehicle.

    The larger opening allows the large air intake to carry away carbon deposits and deposits from the cylinders, thus improving the operation of the engine.

    2. Clean the foam to clean the carbon deposits of the intake valves.

    If there is a plastic insulating cover above the engine, please remove the insulating cover, remove the air duct near the intake valve, and make a record, the side of the intake valve close to the combustion chamber is usually dirty, there are black carbon traces, which is the focus of cleaning, you can use a special detergent or detergent, and wear gloves and masks when cleaning.

    Spray the cleaner where there is a lot of carbon deposits on the intake valves, after 5-10 minutes, use a brush to greatly accelerate the speed of carbon removal, wipe with a towel after removing the dirt, fix the throttle back by position, and install all the air ducts.

    1. Knocking.

    The more carbon deposits on the cylinder wall, the less and less the void in the cylinder, just like installing a wardrobe at home, the more wardrobes, the smaller the volume that can be used in the room, and too much carbon deposition will cause the volume of the cylinder to become smaller, which will affect the compression ratio of the cylinder.

    Compression ratios that are too high can cause engine knocking.

    2. Strain the engine cylinder wall.

    As long as the piston is running, there will be constant friction between the piston and the cylinder wall, and if there is carbon deposit on the piston, then there is a risk that the piston will be pulled against the cylinder wall, and eventually cause damage to the engine.

    3. The increase in fuel consumption and emissions are not up to standard.

    If there is too much carbon deposit, it may also reduce the engine power, increase fuel consumption, and also directly affect the exhaust emissions of the car, resulting in the failure to pass the annual inspection.

    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.

    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.

    Is it necessary to clean up carbon deposits in the intake valves? Is it necessary to clean up carbon deposits in the intake valves? It is necessary to remove 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 valve 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 new oil. 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 in the special cleaning equipment, connect the draft to the key guess air intake system, and use the vacuum to suck the detergent into the air intake Xiaoyan Road to achieve the purpose of cleaning. @2019

    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.

    How to clean up carbon deposits in car intake valves There are three ways to clean up carbon deposits in intake valves: 1. Add "fuel treasure", which is to add detergent to gasoline, which is the easiest to operate, but not very easy to use. If it is a bottle before checking the car, it will have a certain effect.

    In daily use, the cleaning effect of fuel treasure is very small; 2. "Hanging bottles", hanging bottles are very similar to hospital bottles. Cleaning fluid is injected into the intake valve for better cleaning. It doesn't require disassembling the car's engine and is also a more efficient cleaning method; 3. Remove the engine and remove the cylinder head.

    This is the most thorough and direct cleaning method, and the cleaning effect is also the best. However, the process is complicated, and once the engine is removed, it usually loses its original airtightness, and it is best not to remove it for cleaning. @2019
