There is too much carbon in the engine. What should I do?

1, run more at high speed, because the engine is in the best state when running at high speed, and it is in the best state for a long time, which has a certain effect on cleaning up carbon deposits. Proper use of cars can effectively reduce the generation of carbon deposits. Avoid idling for a long time, because the engine does not burn fully at idle speed, which creates opportunities for carbon deposition.

2. Changing the oil regularly can not only make the engine lighter, but also enhance the power. It also has a certain inhibitory effect on the formation of engine carbon deposit. Of course, gasoline is also very important. If the car is filled with the corresponding label of the regular gas station, the full carbon deposit of gasoline will be less. For cars, engine oil is so important to the engine.

3. There are many carbon deposit cleaning agents on the market that can be used to clean carbon deposit, but it is impossible to clean it completely. If this kind of cleaning agent is used frequently, it will cause corrosion and aging of rubber pipes, usually once a year or once every 20 thousand to 30 thousand kilometers, depending on the engine situation. There is no need to disassemble and clean up, unless it is necessary or because of other problems, disassemble and clean up the carbon deposit.

Prevention of automobile carbon deposition

1, don't be idle for a long time.

When idling, the airflow into the engine is small, which can not effectively blow out the carbon deposits in the engine, and idling is not conducive to engine heating. When the engine temperature is low, the volatilization speed of gasoline is slow, which will accelerate the formation of carbon deposit.

Idle operation of air conditioner will bring more load to the engine. However, if waiting for someone only takes a few minutes, there is no need to turn off the engine. Because at the moment of restart, not only the fuel consumption is high, but also the engine will wear out.

2. Low-grade and high-speed

Low-speed gear shifting, also known as "gear shifting", is easy for cars to knock, and insufficient gasoline combustion leads to carbon deposition. But there is no need to artificially increase the shift speed-this will increase fuel consumption and cause premature wear of clutch friction plates. Therefore, the manual transmission car has a displacement of 1.6 ~ 2.0L, which is more economical and practical, and there is no need to improve it; For automatic cars, be careful not to slam on the accelerator.

3. Fill with high-quality gasoline

Impurities such as wax and colloid in gasoline are the main components of carbon deposition, so the carbon deposition trend of high cleanliness gasoline is weak. Unfortunately, at present, the quality of gasoline in China is still low compared with that in developed countries, so we can only briefly talk about it.

It should be noted that high grade does not mean high quality, that is to say, 97 # oil is not necessarily worse than 93 # oil, and grade 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 can effectively prevent the formation of carbon layer on metal surface, and gradually activate the original carbon particles to be removed slowly, thus protecting the engine from damage. However, the addition of gasoline detergent must be cautious. If counterfeit and shoddy products are added, it will have the opposite effect.

4. Check and maintain the engine regularly.

I'm afraid I've heard a lot of news that the use of inferior engine oil causes the engine to "pull the cylinder". In a word, engine oil is the "blood" of the engine, and it should be used according to the condition of the vehicle. It doesn't mean that the higher the better, it is necessary to refer to the mileage, driving environment, self-priming or turbine of the vehicle to formulate a maintenance package suitable for the vehicle.

In addition, pay attention to the parts that are easy to deposit carbon, such as spark plugs, oil circuits and air inlets, and check them one by one to minimize carbon deposition.

5. Pay attention to the timing of the car.

Before turning off the engine of the vehicle, if the vehicle is driving at a low speed for a long time, before turning off the engine, step on the accelerator deeply in the neutral position, use the engine to run at a high speed to impact the carbon deposit, and then turn off the engine after it runs smoothly.

Don't turn off the engine immediately after driving at high speed or climbing a hill, especially for vehicles with turbochargers (the carbon deposition speed of vehicles with turbochargers is several times faster than that of ordinary naturally aspirated vehicles). After idling for a few minutes, try to turn off the engine.
