Please briefly describe how to clean the injector by traditional methods.

First, the first choice is to use the "hanging bottle" for cleaning. This method is simple and easy. During the cleaning process, the carbon accumulated in the cylinder will be washed away, and from the perspective of environmental protection, the exhaust emission will definitely exceed the standard temporarily. Second, the cleaning principle of the disassembly-free cleaning machine is to use the pressure and circulation network of the original engine system to clean the carbon deposit in the cylinder with cleaning agent, instead of burning it with engine oil, and then discharge it through the exhaust system. The advantages of disassembly-free cleaning are convenience and quickness, and the cleaning effect on the oil nozzle is obvious; It can eliminate engine weakness and poor acceleration and improve engine power. The disadvantage of the above method is that the previous section of the air inlet cannot be cleaned and the quality of the nozzle cannot be checked. Third, the cost of cleaning advanced ultrasonic machines is generally high. Unlike the cleaning machine, it needs to remove the nozzle. Its advantage is that ultrasonic can be used to detect atomization, response, switch sensitivity, oil leakage and so on. But it also has disadvantages, because the solenoid valve of the injector does not move during cleaning, and the pinhole of the valve core is not easy to clean.
