How often is best to remove carbon deposits

After the car is used for a period of kilometers, it will definitely produce carbon deposits. Generally, the new car direct injection engine starts to have more obvious carbon deposits at 3000 kilometers. The carbon deposit of 7000 kilometers of EFI vehicles is obvious. This is a 100% problem with fuel-powered vehicles. As a result, the power of the car is insufficient, the smell of the exhaust gas, the idle speed jitter and even the noise become louder, and the exhaust gas detection fails. Generally, the engine deposits are cleaned once every 20,000 kilometers. The following methods can reduce the formation of car carbon: 1. Use high-quality fuel. Because the main component of carbon deposits is formed by the wax and gum deposits in the fuel, the lower the gum content in the fuel, the better; 2. However, we cannot change the quality of the fuel, but we can choose to try not to add cheap fuels of unknown origin; 3. Avoid driving at low speed for a long period of time. If necessary, you can pull the high speed regularly. The principle of pulling high speed to eliminate carbon deposits is to accelerate the gas flow rate, which can take away a small part of the carbon deposits that are not yet firmly attached; So that part of the carbon deposits in the cylinder are burned.
