How many kilometers does it take to remove carbon deposits with dry ice?

[Alexis]

Generally, a vehicle's 50,000-kilometer cycle is the period for cleaning the engine cylinders and removing carbon deposits from the engine. Causes of carbon deposits in car engines: Mainly because after starting the car, when the engine is working, some of the fuel does not burn completely, similar to the principle of burning firewood when cooking at home during childhood. Effects of carbon deposits in car engines: In severe cases, it can cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. Carbon deposits accumulate layer by layer, becoming thicker and thicker, leading to a vicious cycle. In extreme cases, it can block half of the intake valve, eventually causing the engine to burn oil and requiring major repairs.
