How often do you clean up car carbon deposits?

Engine carbon cleaning cycle: once every 50,000-60,000 kilometers. In the process of engine operation, unsaturated olefins and gums in fuel will form a charred substance at high temperature, which is carbon deposition. Therefore, adding high-quality fuel can effectively reduce the carbon deposition of the engine. It takes different time for each car to clean up carbon deposits, but it is recommended to clean up local cars after 20 thousand kilometers and cars that often run at high speed after 30 thousand to 40 thousand kilometers. How to judge that too much carbon deposit needs to be cleaned up: when it is found that the cold car needs to be started normally for many times, the speed is slow and the acceleration is weak, the exhaust gas is pungent, and the fuel consumption is higher than before, then the engine carbon deposit is a bit serious and needs to be cleaned up. Under special circumstances, similar problems will gradually appear in cars that have been driven for more than five years. If the oil is not good, it may accelerate the carbon deposition of the engine. Carbon deposition is common in engines. When driving in urban areas, the driving distance is short and the speed is slow. If the engine runs in the non-economic working area after a long stop-and-go, the idle time is long and the engine speed is low, the air-fuel ratio will be too small to burn completely, and the hydrocarbons and colloid in the fuel will burn into carbon deposits. And these residual carbon deposits have oil absorption characteristics, which will make the incompletely burned gasoline become carbon deposits again, forming a vicious circle. Finally, the engine does not work smoothly, it is difficult to start for a long time, and the fuel consumption increases. In the worst case, the engine will lose its ability to work. Pay attention to the problem of carbon deposition when the fuel consumption of the car increases and the start is weak. Million car purchase subsidy
