For vehicles frequently driven at high speeds, carbon deposits in the combustion chamber should be cleaned every 30,000 to 40,000 kilometers. If the vehicle often operates in congested traffic or idles frequently, it is recommended to clean the deposits every 20,000 to 30,000 kilometers. Carbon deposits refer to a mixture that accumulates on the engine's valves, combustion chamber, and intake pipes. These deposits form when engine fuel does not fully combust, leading to the creation of hydrochloric acid and resin-like gums under high temperature and oxygen catalysis, which adhere to component surfaces. Further exposure to high temperatures concentrates these substances into complex mixtures such as asphaltenes and oil coke. Carbon deposits can be categorized into valve and combustion chamber deposits and intake pipe deposits. Given their significant harm to the engine, timely prevention and removal of carbon deposits are essential.

Is the DMV's Network Disconnection Intentional?

The DMV's network disconnection is not an intentional act. The actual reasons for the vehicle management office's network disconnection are as follows: 1. System upgrade: Like traffic system software games, upgrades can render the internal network unusable, which is a relatively common situation. 2.
