The road conditions are the most annoying things for many people who travel，Urban transportation often shows more congested conditions，This seems to be surprised by everyone，This forces the driver to have to be in a low -speed or idle state，This is the formation of the formation of carbon deposits in virtual。Let's talk about how to prevent carbon accumulation today.

Inlet pipe、Engine Valley、Glutter and Pistons will cause the vehicle itself: the engine power decreases、Increased daily fuel consumption、Difficulties in cold start、Unstable idle speed and shock、Eat emission exceeds the standard。

When the throw is carbon, it will affect the air flow、Affects closedness，It even causes a cylinder to be too low; the most direct impact on the accumulation of carbon deposits on the fuel injection mouth is insufficient fuel supply; when the piston accumulation is severe, the piston cylinder wall will be scratched and caused the air leakage or even the piston ring card to death. Case。

1. Do not drive for a long time 

When driving idle，Small airflow entering the engine，Can't effectively blow out the accumulation of carbon in the engine，And idle driving is not conducive to the engine heating，When the engine temperature is low，Slow of gasoline volatilization，will accelerate the formation of carbon deposits。Run in the idle state of the air conditioner，It will also cause a load to the engine。but but，If you wait for a few minutes，No need to turn off the fire。Because of the moment of restarting，Not only high fuel consumption，It will also cause wear to the engine。

2. Low -end high -speed 

Low -speed speed shifting，It is often called "drag"，The car is easy to shock，Insufficient burning of gasoline leads to carbon deposits。But it is not necessary to increase the speed shifting speed -this will increase fuel consumption，and cause the clutch rubbing tablet prematurely。So，Manual transmission car，1.6 ～ 2.0L displacement，2000 rpm shift is more economical，No need to improve; while automatic transmission car，Be careful not to add the fuel door。

3. Inject high -quality gasoline 

Unsure such as wax and glue in gasoline is the main ingredient for forming carbon，So the trend of carbon deposits with high cleanliness gasoline is weaker。Unfortunate is，At present, the quality of gasoline in my country is lower than that of developed countries，It can only be brief because it is bad。Everyone should pay attention to the high standard number is not equal to high quality，That is to say, the oil on No. 97 is not necessarily less than the impurities on No. 93，Label only represents the octane value of the oil，Can't represent quality and cleanliness。

Some car owners in order to ensure the cleanliness of gasoline，The method of adding gasoline cleaner to gasoline。This can effectively prevent the formation of carbon -accumulating layer on the metal surface，and can gradually activate the original carbon -stagnant particles slowly remove，to protect the engine from damage。But the addition of gasoline cleaner must be cautious，If the product that adds fake and shoddy will get the opposite effect。

4. Regularly check the maintenance engine 

I am afraid I heard a lot of news that uses inferior oil to cause the engine to "pull the cylinder"。In short，Machine oil is the "blood" of the engine，and use the use of the car condition，Is not to say that the higher the price, the better，Refer to the mileage of the vehicle、Driving environment，Self -suction or turbine，Come on to formulate a maintenance package suitable for car love。Another，Pay seabet appattention to spark plugs、Oil Road、Evaporate carbon parts such as air -to -air channels to investigate and clean，Reduce carbon deposits as much as possible。

5. Pay attention to the timing of the car 

Before turning off the vehicle engine，If the vehicle has a long speed driving time，It is recommended to step on a few accelerators in the vacant position before turning off the stall，Use the engine to run high -speed operation to impact carbon，and other running out after running smoothly。Do not turn off immediately after driving at high speed or climbing.，Especially models equipped with turbochargers (a turbocharger vehicle forms a speed faster than ordinary naturally aspirated vehicles)，Try to run the engine for a few minutes as much as possible before turning off the engine。

6. Fuel additive 

fuel additives are directly added in the fuel tank，Make gasoline burn more! The main role is to make up for the vehicle problem caused by the ingredients in the formula and the additive to make up for the lack of fuel's own quality，From a functional point of view，The amino substances in some fuel additives can clean the accumulated carbon stagnant material accumulated in the engine system，Frequent use can inhibit carbon production，Reduce engine abnormality caused by carbon deposits，There are also some fuel additives that can improve the fuel's alkane value to a certain extent，Reduce or eliminate engine burst due to insufficient fuel alkane。But just improvement，Generally, it will not be immediate。

7. Running at high speed 

Theoretically speaking，The idle fierce inside door will rinse some carbon deposits，But this method is not recommended。First is a waste of gasoline，Pollution environment; second，The air rotation is not good for the engine。Especially the speed reaches 4 000 ride above，If you are not running on the road，No wind blows in to cool down the engine，Will affect the engine。I really want to flush the carbon deposit with the air，Go to the high speed!

Summary:Finally, I still emphasize，The engine producing carbon accumulation is normal，Is it unavoidable，If the phenomenon is not serious，Make some so -called cleaning projects blindly，Not only is the cost performance not high，and may be damaged to other parts of the car。But if not paid attention to，Will be at the power，Affordable impact in fuel consumption。Still preventive。
