How many kilometers do you often run at high speed and need to clean up carbon deposits?

Generally speaking, running at a high speed of 50,000 kilometers often requires cleaning up carbon deposits.

Carbon deposition is a colloidal substance produced by unsaturated olefins and gums in fuel at high temperature during engine operation. Now the engine manufacturing technology is very advanced, but the efficiency of the combustion chamber is only 35%-50%, and the formation of carbon deposit is difficult to avoid. However, there are still many ways to reduce carbon deposition. First of all, don't start the car cold, warm it up at idle speed for 3-5 minutes before starting it; Secondly, often run at high speed, run a section of road at the speed of 120km/h, and use the scouring effect of airflow on the air inlet to reduce the accumulation of carbon deposits; Furthermore, it is suggested that car owners clean the oil circuit and air intake system every 20,000-40,000 kilometers, and only in this way can the carbon deposit be completely removed.

When the carbon deposit is attached to the cylinder and piston top, the volume of the combustion chamber will decrease and the compression ratio of the cylinder will increase. If the compression ratio is too high, the engine will knock and reduce the engine power. If carbon deposits adhere to the valve, it will increase the weight of the valve, and the valve will easily cause disharmony when it moves up and down repeatedly at high speed, resulting in a lot of power loss, resulting in more fuel consumption, weak automobile performance and serious exhaust gas exceeding the standard. Removing carbon deposits has many advantages, such as improving vehicle horsepower, saving fuel consumption, reducing knock point, prolonging engine life and improving braking performance.

In order to really reduce carbon deposition, it is necessary to develop good driving habits, that is, to avoid hot cars for too long and idling for a long time. And don't do some so-called cleaning projects at will, which is not only uneconomical, but also may damage other parts of the car. It is normal for cars to have a certain degree of carbon deposition.
