3 Operation process
3.1 Ultrasonic cleaning
Ultrasonic cleaning is to use the penetrating and cavitation shock waves generated
when ultrasonic waves propagate in the medium, and powerfully clean objects with
complex shapes, cavities and pores to completely remove stubborn carbon
deposits on the fuel injector.
3.1.1 Preparation
1) Remove the fuel injector from the vehicle and check whether its rubber seal is
damaged. If it is damaged, it should be replaced in time before the cleaning test to
avoid leakage during the test. Then put the fuel injection nozzle into the cleaning
agent, carefully remove the external grease and wipe it with a soft cloth.
2) Turn on the power and turn on the power switch on the side of the main unit.
3) Put the cleaning bracket in the accessories into the ultrasonic cleaning tank, and
place the wiped fuel injector in the cleaning bracket positioning hole of the
ultrasonic tank.
3.1.2 Methods and steps
1) Add an appropriate amount of cleaning agent to the ultrasonic tank and
spread the cleaning agent over the bottom of the cleaning stand.
