How many kilometers of throttle and nozzle need cleaning?

If the throttle is not based on kilometers, it depends on the local environment and the cleanliness of the trachea when maintaining the car. You can clean the nozzle once every 20,000 kilometers, or you can add the nozzle cleaning solution to the oil tank for cleaning. The oil amount is directly proportional to the amount of cleaning solution.

When cleaning the throttle valve, it is not necessary to disassemble it, but the sealing part of the inlet steam must be cleaned, and the idle motor must be disassembled to clean it. Nozzle borrowing and cleaning without disassembly have their own advantages and disadvantages.

Generally speaking, it is recommended that the maintenance station avoid disassembly and washing to prevent other unnecessary waste, such as the need to replace the sealing ring or install some other gaskets after disassembly, or the oil leakage during disassembly and assembly, which will delay the owner's time.

Extended data:

After cleaning, follow the disassembly procedure just now, and then start the initialization of the throttle valve after installation. After cleaning the throttle, it needs to be initialized;

Because the computer has a memory function when adjusting the throttle opening. Because there was sludge blockage in the past, in order to ensure air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.

But there is no sludge blockage after cleaning. If the throttle valve still maintains its previous opening, it will cause excessive intake air. As a result, the engine will shake when starting, and the acceleration will be weak, and the engine fault light may light up.
