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、The fuel injection mouth and the piston accumulation will cause the vehicle itself: the engine power decreases、Increased daily fuel consumption、Difficulties in cold start、Unstable idle speed and shock、Eat emission exceeding the standard。

When the throw carbon deposits, it will affect the flow of air、Affects closedness，It even causes a cylinder to be too low; the most direct impact on the accumulation of carbon deposit 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 at idle speed，Small airflow entering the engine，Can't effectively blow the carbon deposits in the engine，And idle driving is not conducive to the engine heating，When the engine temperature is low，Slow of gasoline volatilization，It will speed up the formation of carbon deposits。Air conditioning runs in idle state，It will also cause a load to the engine。but but，If you just need 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 shift gear，It is often called "drag"，The car is easy to explode，Inadequate burning of gasoline leads to carbon deposits。But it is not necessary to increase the speed of shifting shifting -it will increase fuel consumption，and cause the clutch rubbing tablet premature wear。So，Manual transmission car，1.6 ～ 2.0L displacement，2000 rpm for about shift is more economical，No need to improve; while automatic transmission car，Be careful not to add the throttle。

3. Inject high -quality gasoline 

Unsure such as wax and glue in gasoline is the main component of carbon accumulation，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 simple because of 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 -storage 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 motor oil to cause the engine "pull the cylinder"。In short，Machine oil is the "blood" of the engine，And use the use of the car condition，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 the maintenance package suitable for car seabet applove。Another，Pay attention to spark plugs、Oil Road、Inlet roads and other carbon parts can be investigated and cleaned，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 pins in the vacant position before turning off，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 for forming carbon deposits is more faster than ordinary naturally aspirated vehicles)，Try to run the engine after a few minutes of idle operation。

6. fuel additive 

fuel additives are directly added in the fuel tank，Can 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 amine substances in some fuel additives can clean the accumulated carbon in the engine system，Frequent use can inhibit the production of carbon deposits，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 the engine burst due to insufficient fuel alkane。But just improvement，Generally, it will not be immediate。

7. Run 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 rpm 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，Still go to the high speed!

Summary:Finally, I still emphasize，The production of the engine to produce carbon deposits is normal，Is it unavoidable，If the phenomenon is not serious，Blind doing some so -called cleaning projects，Not only is the cost performance not high，and may be damaged to other parts of the car。But if you don't pay attention to，Will be for power，In terms of fuel consumption, it has an adverse effect。Still preventive。
