How to prevent carbon deposits in cars? 10

When using low-quality gasoline with a lot of impurities, valve carbon deposits can be severe and form faster. Because the structure of carbon deposition is similar to that of a sponge, when the valve forms carbon deposition, a part of the fuel injected into the cylinder will be adsorbed, which makes the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and abnormal phenomena such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If it is serious, it will cause the valve to be closed loosely, so that a cylinder will not work completely due to no cylinder pressure, and even adhere to the valve to prevent it from returning.

At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

How to prevent carbon deposition in automobiles is also a must-do for car owners, to maintain their cars, first of all, the car owner starts with the prevention of carbon deposition. Let's talk about how to effectively avoid carbon deposits!

1.Run more at high speeds and try to increase the shift speed of the handstop car.

The purpose of running more high-speed is to use the scouring effect of the air flow on the 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.

2.Do not idle for long periods of time.

The longer the idle time, the longer it takes for the engine to reach normal temperatures, and the slower the rate at which the gasoline is evaporated when it is injected into the back of the valve, resulting in 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.

3.Pay attention to the timing of the flameout.

For cars equipped with turbochargers, do not turn off the engine immediately after driving at high speed or climbing hills, and turn off the engine after idling for 10 minutes, and the car equipped with a turbocharger will form carbon deposits several times faster than ordinary naturally aspirated cars.

4.Fill with high-quality gasoline.

The impurities in gasoline are the main components of carbon deposition, so the tendency of carbon deposition in gasoline with high cleanliness is weaker. However, it should be noted that a high grade does not equal high quality, and the label only represents the octane number of the oil, not the quality and cleanliness.

In order to ensure the cleanliness of gasoline, some car owners will adopt the practice of adding gasoline detergent to gasoline. This effectively prevents the formation of carbon deposits on the metal surface, and can gradually activate the original carbon particles and slowly remove them, thus protecting the engine from damage. However, the addition of gasoline detergent must be cautious, if you add shoddy products, you will get the opposite effect.

Tips: There are car owners in the routine maintenance are satisfied under the condition of every 20,000 to 40,000 kilometers to do the air intake system without dismantling the cleaning, that is, under the premise of the engine does not dismantle, use special equipment and special methods to clear the carbon deposition of the vehicle's air intake, valve, oil circuit and other parts that are easy to form carbon deposits.

26 How to Prevent Carbon Deposition in Cars?

Carbon deposits in the engine can really cause a lot of bad effects. A lot of people are concerned about how to clean up the carbon deposits in the engine. In fact, it is more practical to do a good job of prevention than to clean up. So how to prevent carbon deposits in the engine in daily life? I suggest you take a good look.

1.It's not easy to idle for too long. Driving at idle speed for a long time is prone to generate a large amount of carbon deposits, so it is not recommended to idle for a long time. Its gasoline evaporates very slowly, which accelerates the formation of carbon accumulation and easily causes engine load. It is not advisable to do so.

2.Drive at low speeds. The so-called operation is low-speed shifting. At this time, the combustion of gasoline is very incomplete, which can easily lead to high fuel consumption. So it's better to shift gears at high speeds. Of course, the automatic stupid Jane noisy gearbox should be careful not to refuel violently.

3.Check the engine regularly. Carbon deposition is one of the most important problems in the engine, so the daily maintenance of the engine can also avoid excessive carbon deposition. In addition to changing the oil, it is also necessary to check the spark plug and oil circuit to prevent carbon build-up.

4.Run more high-speed. Idling throttle washes away carbon buildup, but it's not recommended. When driving at high speeds, it is best to wash away the carbon deposits with air streams. Do you remember?

Of course, carbon deposition in the engine is a relatively normal situation, and it is unrealistic to prevent it completely, so we still need to be cautious to take these precautions to avoid excessive carbon deposition.

Millions of car purchase subsidies.

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.

If you start the car, carbon accumulation occurs. To reduce carbon accumulation, car owners must change your attitude towards cars. If you want to save as much money as possible, the car will definitely not give you a good job.

It's all complementary. Of course, sprays are not complementary. Because he can reverse black and white.

There is a lot of carbon deposition on the car. Throttle carbon deposits, valve carbon deposits, combustion chamber carbon deposits, oil circuit carbon deposits, exhaust gas carbon deposits, etc. Throttle Carbon (To reduce the production of throttle carbon, the balance air cleaner must be replaced regularly.)

Never be patient, blow and blow. This is the word we hear the most in our daily life. Won't say cars.

If you can talk about cars, I believe it. I don't want to have a husband like that. The valve carbon natural intake model (except for direct injection in the cylinder) is rarely driven at high speeds, and is mostly used in urban vehicles.

If the engine doesn't function smoothly, the valve carbon increases. To reduce valve carbon, it is necessary to drive at high speed on a regular basis, which complements the throttle carbon! Carbon product of oil circuits:

It's simple. The quality of the oil is not up to standard, and there are many impurities. After a long time, the oil circuit and fuel injector are blocked, and in serious cases, the vehicle cannot be started.

If you want to reduce carbon deposition in the oil circuit, try to choose two barrels of oil and don't go to the private sector. There are also bad things in 2 barrels of oil, but the probability is high and there are no problems. Carbon deposition in the combustion chamber:

This is also complementary to throttle and oil circuit carbon deposits. The replacement quality of the air filter is poor, the filtration effect is poor, the fine impurities enter the combustion chamber for combustion, and the oil impurities are mixed with the air, and the two combine to produce more impurities. Reducing carbon deposits in the combustion chamber requires efforts in air intake and fuel.

Exhaust gas deposition: To put it bluntly, it is the three-way destruction of blockage. This one needs to be cleaned regularly.

Generally, it is cleaned once in about 30,000 kilometers. To solve this problem, all the above problems must be addressed. If we don't solve the problem, we won't be able to solve it.

And, of course, the driving habits of the driver. Frequent violent driving and not running at high speeds are also the main causes of carbon deposit. Regular high-speed driving, avoid violent driving, need to clean, need to replace cleaning, save dozens of yuan, do not have follow-up continuity problems!

<> "How to avoid carbon deposits in cars, here are a few tips.

1.Carbon. Carbon carbon refers to the shape of an unsaturated olefin and colloid, one of the unsaturated olefins and colloids in the fuel in the engine, the high temperature state of the engine.

How is automotive carbon formed?

1).Long-term low speed.

A long period of low speed will make the engine's fuel completely burned, and it will produce carbon for a long time.

2).Long-term idle parking.

Long idling, the time it takes for the engine to reach a normal temperature, injects the speed of gasoline into the rear of the valve.

At the same time, drive often. The flow of air into the engine is small, which makes the flushing of carbon very weak.

3).Press the throttle regularly.

Strikes, the throttle will cause the injection to be too large, the engine will not burn completely and completely, there will be an incompatibility problem.

4).Stop the fire after a long time.

Most models now use turbochargers, and after a long period of operation, the turbine pressure reaches thousands of degrees, and the immediate flameout may cause the turbocharger to cool down, and excessive temperatures can ignite the retained oil-gas mixture, forming carbon on the turbine.

5).Add high shed label oil.

Many car owners consider high standards of oil to be clean.

However, the high mark of gasoline represents the mark of octane number. Octane is a substance that inhibits combustion.

Long-term use of high-inhibition combustion gasoline will also produce carbon.

How to avoid carbon formation.

Common sense 1: Avoid excessive extinguishing speed.

Thirteen seconds after stopping the park, turn off within one minute so that the burning gasoline is completely burned.

Common sense 2: Avoid accidental idling.

When traveling, if you need to wait, you need to wait for a long time. It is advisable not to wait for idleness, you can turn off the car directly.

Common sense 3: Add regular fuel.

Common sense 4: Clean the throttle regularly.

If the car's carbon is relatively severe, I can feel a noticeable improvement after cleaning. Power and fuel consumption are definitely more advantageous than before.

Common Sense 5: Use road segments as much as possible while driving.

When driving, avoiding traffic segments can directly avoid the carbon generation, and you can plan your travel route before you go out. Select a highway or an uncovered section of the road.

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 deposits is that the fuel is not completely burned, and it attaches to various parts of the engine, which can form 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 unspecified 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 carbon deposits in time, it will not only cause a certain degree of harm to the car, but also the harm to the environment is only great, 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 an overall oil circuit carbon deposit, and if the carbon deposits are not cleaned up for a long time, the operation of the whole vehicle will be caused by carbon deposits, so that the internal channel of the engine is blocked by carbon deposits, and the internal fuel injection of the car is not smooth, so that the engine power becomes worse, As a result, the power of the automobile engine is reduced, the fuel consumption is increased, and the combustion rate is too low.
