Road conditions are the most annoying thing for many people traveling by car，Urban traffic is often congested，Everyone seems to be familiar with this，This forces the driver to be in a low speed or idling state，This invisibly aggravates the formation of carbon deposits。Today we will talk about how to prevent carbon deposits.

Intake pipe、Engine valve、Carbon deposits on the fuel injector and piston will cause the following to the vehicle itself: reduced engine power、Increased daily fuel consumption、Difficulty in cold start、Unsteady idle speed and knocking、Emission exceeds standard。

When carbon deposits occur on the throttle, it will affect the intake air flow、Affects closure，It may even cause the cylinder pressure of a certain cylinder to be too low；The most direct impact on carbon deposition in the fuel injection nozzle is insufficient fuel supply；When the carbon deposit on the piston is severe, it will scratch the cylinder wall of the piston and cause air leakage or even stuck piston rings。

1. Do not idle for a long time 

While idling，Smaller airflow entering the engine，Cannot effectively blow out the carbon deposits in the engine，And driving at idle speed is not conducive to engine heating，When the engine temperature is low，Gasoline evaporates slowly，Will accelerate the formation of carbon deposits。The air conditioner is running at idle speed，It will also put a load on the engine。However，If it only takes a few minutes to wait for someone，No need to turn off the engine。Because of the moment of restart，Not only high fuel consumption，It will also cause wear seabet ioand tear on the engine。

2. Low-end and high-speed 

Low RPM shifting，It is often called "drag block"，Cars tend to explode，Incomplete combustion of gasoline leads to carbon deposition。But there is no need to artificially increase the shifting speed - this will increase fuel consumption，And cause premature wear of the clutch friction plate。So，Manual transmission car，1.6～2.0L displacement，It is more economical to shift gears around 2000 rpm，No need to improve;And 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 deposits，So the tendency of gasoline with high purity to form carbon deposits is weaker。Unfortunately，At present, the quality of gasoline in our country is still low compared with developed countries，I can only make do with the simplicity。Everyone should pay attention to the fact that high quality does not mean high quality，In other words, No. 97 oil does not necessarily have fewer impurities than No. 93 oil，The label only represents the octane number of the oil，Does not represent quality and cleanliness。

Some car owners want to ensure the cleanliness of gasoline，Will add gasoline detergent to gasoline。This can effectively prevent 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, you must be careful when adding gasoline detergent，If you add fake and inferior products, you will get the opposite effect。

4. Regularly inspect and maintain the engine 

I’m afraid I’ve heard a lot of news about the use of inferior engine oil causing engine “cracking”。Anyway，Motor oil is the "blood" of the engine，And it must be used according to the vehicle conditions，It does not mean that the higher the price, the better，Multiple reference vehicle mileage、Driving environment，Self-priming or turbine，To develop a maintenance package suitable for your car。Also，Pay attention to seabet iothe spark plug、Oil line、Check and clean parts prone to carbon deposits such as air intake ducts，Reduce carbon deposits as much as possible。

5. Pay attention to the timing of killing the car 

Before turning off the vehicle engine，If the vehicle drives at low speed for a long time，It is recommended to step deeply on the accelerator in neutral position before turning off the engine，Use the engine to run at high speed to attack the carbon deposits，Wait until the operation is stable before turning off the engine。Do not turn off the engine immediately after driving at high speed or climbing a hill，Especially models equipped with turbochargers (vehicles equipped with turbochargers form carbon deposits several times faster than ordinary naturally aspirated vehicles)，Try to idle for a few minutes before turning off the engine。

6.Fuel additive 

Fuel additives are added directly to the fuel tank，Enables gasoline to burn more fully！The main function is to rely on the ingredients in the formula and additives to make up for vehicle problems caused by the lack of fuel quality，From a functional perspective，The amines in some fuel additives can clean the carbon deposits accumulated over time in the engine system，Regular use can inhibit the production of carbon deposits，Reduce engine abnormalities caused by carbon deposition，There are also some fuel additives that can improve the octane number of fuel to a certain extent，Reduce or eliminate engine knocking caused by insufficient fuel octane。But it’s just an improvement，Generally no immediate results。

7.Run on the highway 

Theoretically，Severely accelerating at idle speed will flush away some carbon deposits，But this method is not recommended。First of all, it is a waste of gasoline，Polluting the environment；Secondly，Idling is bad for the engine。Especially when the speed reaches 4 000 rpm and above，If you are not running on the road，There is no wind blowing in to cool down the engine，It will affect the engine。I really want to use air flow to wash away the carbon deposits，seabet appLet’s run on the highway!

Summary:Last emphasis is given，It is normal for the engine to produce carbon deposits，It is inevitable，If the phenomenon is not serious，Blindly doing some so-called cleaning projects，Not only is the price/performance ratio not high，And it may cause damage to other parts of the car。But if you don’t pay attention，Will be motivated，Adverse effects on fuel consumption。Prevention is still the priority。
