Is the automobile fuel nozzle cleaned by hanging bottle method?

Automobile fuel nozzles cannot be cleaned with hanging bottles. Hanging bottle washing is the previous method, and the hanging bottle method has been gradually eliminated because the operation process is too complicated and the deposited carbon can not be completely cleaned. At present, the cleaning machine mostly adopts the way of pumping cleaning agent instead of gasoline pump, that is, pouring the cleaning agent into the cleaning machine, connecting the cleaning machine to the oil circuit of the engine, disconnecting the gasoline pump, starting the engine, and idling for more than 15 minutes until the cleaning agent is used up.

Cleaning the fuel injector does not have a certain mileage, but depends on the working condition of the engine. Some cars may need cleaning about 40,000 kilometers, some cars may need cleaning about 80,000 kilometers, and some cars may not need cleaning about 6,543,800 kilometers. Gasoline is much cleaner now than before. If you can keep a high speed when driving, the distance to clean the nozzle will be longer. Generally, the nozzle can be cleaned by "disassembly-free cleaning method", that is, the nozzle can be cleaned at the same time as the oil circuit is cleaned.
