Can extreme driving remove carbon deposits? Does slamming the throttle in neutral remove carbon depo

At high speeds, the principle can remove carbon deposits, but the effect is not good, and it does not play any role. It is best to clean the car first and then drive at high speed for a period of time, so that the carbon deposits in the engine are easy to remove, but it feels more than the original waste oil, which is a normal imagination.

Many car owners often hear such a voice in the process of using the car, perhaps the maintenance master said: "Your car has carbon deposits, you need to deep clean to remove carbon and oil stains." ”

But the friends around me said: I drove 100,000 kilometers and never cleaned the carbon deposits, and the car was still fine.

This makes the car owners and friends scratch their heads, as if everyone is right, and it seems that no one is right.

To understand this situation, we must first understand what carbon deposition is.

What exactly is carbon deposit?

When it comes to carbon deposits, it feels very professional, but carbon deposits are not so difficult to understand.

In the image below, the black or black-brown sediment we see is carbon deposit.

There is a difference between carbon deposits and no carbon deposits in the intake valves.

There are many reasons for carbon deposition, the most important factor is the product formed by insufficient fuel combustion during the working process of the engine, which is generally attached to the intake manifold, fuel injector, throttle, oil pipeline, spark plug and other parts.

With current technology, there is no engine that can make 100% gasoline burn sufficiently. It can be said that as long as it is a fuel vehicle, the generation of carbon deposits cannot be avoided.

Do you have to clean it with carbon deposits?

According to a supervisor of the after-sales service department of a 4S store, a certain amount of carbon deposition is allowed:

Generally speaking, our store will recommend that the owner clean up the carbon deposit once 20,000-30,000 kilometers, and the carbon deposit is not cleaned up as often as possible, and there is no need to spend extra money when the vehicle performance is normal.

Therefore, some repair and maintenance shops say that "your car has carbon deposits, you have to remove it quickly", which is irresponsible and misleading.

Of course, the accumulation of too much carbon deposits does bring some problems. This can cause the engine to not work properly and occasionally stall, such as:

Carbon deposits in the combustion chamber, which can cause engine knocking.

Carbon accumulation on the fuel injector will cause the engine to shake and accelerate poorly.

The carbon deposition of the throttle valve will cause the vehicle to accelerate weakly, idle shaking, or not maintain a stable value at idle, so that it is difficult to start and increase fuel consumption.

When the carbon deposits are serious enough to cause substantial damage to the engine, they must be removed.

How do I clean up carbon deposits in my engine?

Carbon deposits are the most common in throttle valves, intake manifolds, intake and exhaust valves, valve linkages, fuel injectors, combustion chambers, etc.

Depending on the location and degree of accumulation, the method of cleaning up the carbon deposits is also different.

Don't listen to rumors. Carbon deposits in engines are hard inorganic substances that accumulate over a long period of time. It is a mixture of some impurities that have not been fully burned fuel residues, etc.

If you disassemble the engine, it is more difficult to physically clean up the carbon deposits in the combustion chamber, especially if you only clean it up by increasing the rpm. The so-called violent driving is nothing more than pulling up the rpm, increasing the throttle opening, and increasing the air intake of the engine. That's all.

To put it bluntly, it is to let the air blow the carbon deposits of the engine off. This possibility is almost nil.

Second, check and replace the air cleaner frequently. Clean the throttle.

Third, do not drive at high and low speed for a long time. Insufficient combustion of the engine can easily lead to carbon deposits.

Can a car run at high speed to clean up carbon deposits? Why?

No, after the run-in period, you only need to run at high speed, and the speed of the car is 100, and the limit will hurt the engine.

Personal opinion.

Deliberately pull the high speed.

There is no need. The current manufacturing process and car environment are much better than before.

First of all, it is a relatively long process to remove carbon deposits. The engine maintains medium and high speed operation, at this time, the engine air intake is relatively large, the air intake is smooth, and there is an effect of removing carbon deposits, but if the carbon deposits are more serious, it still cannot be removed, but it is suitable for regular use of the engine to avoid serious carbon deposition in the engine, so the car can not always run at low speed.

1. Neutral gear refers to the state that the motor vehicle gear lever is not put into any forward or reverse gear, and the gearbox is completely separated from the engine. The neutral of the manual transmission is in the middle position, while the neutral of the automatic transmission is"n"Signs.

2. Neutral coasting has always been a more fuel-efficient operation, especially the vast majority of truck drivers, who often use ignition and neutral coasting to save fuel. However, for the current EFI engine car, the neutral coasting operation must be used cautiously, and the ignition and neutral coasting cannot be used.

The power of the engine comes from the engine piston moving downward, the mixture of gasoline and air is sucked into the cylinder, and then the piston moving upwards compresses the oil and gas into a highly combustible gas, and finally the spark plug ignition detonates it, and the piston is pushed by this powerful force, and the engine generates power. The source of power, the mixture, must enter the combustion chamber through the intake valve; A small part of the gasoline will adhere to the intake valve, in the case of high temperature of the engine, the gasoline can not be burned completely hydrocarbon, paraffin, gum will be burned into glue carbon, if the injector has dirt, the sprayed gasoline atomization state is not good, gasoline and air are mixed unevenly, will increase the amount of gasoline condensed in the intake valve. The bad thing is that the rubber carbon has the property of absorbing gasoline, so this layer of carbon will absorb gasoline, and the absorbed gasoline will be burned into rubber carbon to form a thicker carbon deposit, and the thicker carbon deposit will absorb more gasoline, and so on until the intake valve cannot be closed due to too much carbon deposit, so that the engine cannot be operated.

The carbon deposition in the combustion chamber is caused by the gum in the gasoline composition and the hydrocarbons that cannot be fully detonated, and the tiny carbon particles produced are not discharged with the exhaust gas and accumulate in the combustion chamber, and these black particles should be emitted into the atmosphere with the exhaust gas, or accumulate on the muffler pipe. If the carbon deposition in the combustion chamber is serious, the temperature of the combustion chamber will rise, causing the spark plug to ignite at the same time, and the mixture in the combustion chamber will also detonate by itself. The condition of carbon deposits in the combustion chamber can be known by looking at the ignition end of the spark plug.

1. Add cleaning agent to the fuel.

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.

Almost everyone knows the carbon deposits in the engine, but when to clean them up means that the owner learns to judge that the engine has carbon deposits, and the carbon deposits are relatively large. Usually, the car engine has a lot of carbon deposits, and there will be the following conditions:

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.

Operation: 1. The car hangs the bottle. A bottle-shaped tool is hung above the engine, and then the detergent is poured into the bottle tool and introduced into the engine through the catheter to clean the carbon deposit.

2. Machine wash. The cleaning agent is injected into a machine, and then the machine pressurizes the combustion chamber to let the cleaning agent react with the carbon deposit to dissolve, and then the waste liquid is pumped out. 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.

3. Engine disassembly and washing. This method should be the most effective, directly remove the entire engine, and use detergent, ultrasonic and other methods to completely and thoroughly remove the carbon deposits on the parts. However, it can be seen that it takes a lot of time and effort to disassemble and clean the engine, and ** is naturally the most expensive.

Tamper-free products can be purchased for cleaning.

When the vehicle needs to be serviced, when it is time, add the product to the engine oil and run for one hour, and change the engine oil.

Gasoline can also be added to cleaning.

Engine decarbonization may involve the disassembly and assembly of components, as well as precautions, and it is not recommended for car owners to operate by themselves.

Three methods:

1. Use fuel additives.

2. Repair shop to hang bottles.

3. Dismantle and dismantle.

Tamper-free products can be purchased for cleaning.

The main reasons for the formation of carbon deposits are as follows.

First, the vehicle travel time is short, no more than 30 kilometers per day, and the driving speed is low, second, the gasoline mark used is too low, the combustion performance is not good, third, the engine valve oil seal, piston ring sealing effect is poor, and the phenomenon of burning engine oil occurs, on the one hand, because of the crankcase forced ventilation system, which is not suitable for the installation of oil and gas separator, resulting in the burning of engine oil.

Can a car engine remove carbon deposits on its own? How does it work? What you can normally do is buy a bottle of fuel and add it and stick to it for a while.

But if the carbon deposits are severe, it doesn't help. Unless you're a professional and have some social equipment, disassemble and clean the engine yourself. Can a car engine remove carbon deposits on its own?

What you can normally do is buy a bottle of fuel and add it and stick to it for a while. But if the carbon deposits are severe, it doesn't help. Unless you're a professional and have some social equipment, disassemble and clean the engine yourself.

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.

1. 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. Same.

When idling frequently, the flow of air into the engine is small, so the scouring effect on carbon deposits becomes weak, which will promote the deposition of carbon deposits.

2. Run more high-speed and try to increase the shift speed of the hand-stop 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 gear shifting is also similar to running at high speeds.

With the same skill, changing the original gear shift at 2000 rpm to 2500 conversion can not only effectively prevent the generation of carbon deposits, but also improve the power of the car, and also avoid.

Detonation caused by too low a shift speed protects the engine.

3. Pay attention to the timing of the car extinguishment.

For cars equipped with turbochargers, do not stop the car immediately after driving at high speed or climbing hills, and stop the car after idling for 10 minutes, because it is equipped with turbocharging.

The rate of carbon accumulation in cars is several times faster than that of ordinary naturally aspirated cars.
