How often is the air inlet cleaned?

The air inlet is washed every 20,000-40,000 kilometers. There are generally two ways to clean the air inlet: bottle washing and disassembly cleaning, and bottle washing is the most mainstream form at present. In this way, the cleaning agent is sucked into the engine combustion chamber together with the intake airflow of the engine intake pipe in the form of bottle washing, and in this process, the cleaning agent will clean the engine intake, especially the throttle position. Inlet refers to the inlet and passage of air required by jet engine. The intake port not only provides a certain amount of air for the engine, but also ensures the normal operation of the compressor and combustion chamber.
