How to disassemble and clean the nozzle of Wuling Light by yourself?

At present, the cleaning of electronically controlled automobile fuel system is mainly due to the control characteristics of EFI engine. The technical principle is that every time the cylinder works, fuel is injected first and then ignited. When we put out the engine, the ignition device was cut off immediately. However, the gasoline sprayed by this working cycle cannot be recovered and can only be attached to the intake valve and the combustion chamber wall. Gasoline volatilizes easily, but the wax and gum in gasoline will stay. In the long run, after repeated heating, the wax and gum in gasoline accumulate thicker and thicker. In addition, if the engine condition is not good, such as burning engine oil or filling gasoline with poor quality and many impurities, the valve carbon deposit will be more serious and form faster. Secondly, another factor that needs to clean the fuel nozzle regularly is the current structure of the fuel nozzle. At present, the fuel nozzle of the vehicle has been developed from the previous 1~2 hole to16 hole. In order to better control the mixing ratio of fuel and air, improve fuel efficiency and reduce emissions, the accuracy of the fuel nozzle of the EFI vehicle has been greatly improved, which also leads to glue and glue in the fuel. Therefore, cleaning the fuel nozzle and intake system of electronically controlled engine is a routine maintenance project at present. The benefits of cleaning the fuel nozzle include qualified exhaust emission, fuel economy, service life of three-way catalyst, power performance, idle temperature, good cold start and so on.
