Using Ultrasonic Cleaning for Fuel Injectors

There are traditional methods of cleaning fuel injectors such as soaking them in harsh chemicals, forcing solvents through the injector at high pressure, or removing the deposits manually. These traditional cleaning methods do not guarantee the complete removal of deposits, and they may even damage the injector.

Ultrasonic cleaning systems, on the other hand, do not involve the use of harsh solvents or slow, manual cleaning. Furthermore, it is an excellent alternative that doesn't suffer from the same drawbacks and it cleans items -- even fuel injectors heavy with deposits -- quickly and thoroughly.

A fuel injector is placed in a cleaning tank that has an ultrasonic transducer installed at the bottom or on the walls (a portable transducer can also be used in the cleaning solution).

The ultrasonic transducer is powered by an ultrasonic generator that supplies the high-frequency electrical signal (the normal signal is usually 30 kHz). The ultrasonic cleaning system transducer generates ultrasonic waves in the cleaning solution, causing them to produce cavitation bubbles. These bubbles act as cleaning agents for hard metal surfaces like those of fuel injectors. When the bubbles collapse, they dislodge contaminants and deposits from the surface of fuel injectors.

The bubbles travel wherever the cleaning solution is present, so ultrasonic cleaning works outside, inside and in every part of fuel injectors. It even cleans hard-to-reach places, something that traditional cleaning cannot do. As a result, the deposits are removed from inside fuel injector holes, from threads, and from couplings. All foreign material is removed and cleaned down to the bare metal. Ultrasonic cleaning is also fast, taking from 10 to 20 minutes for the cleaning cycle.
