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.

3 Big Cost Savings Benefits of Using Ultrasonic Cleaners vs. Spray Washers

If there's one thing that business and facilities owners want when they're considering a cleaning solution, it should be cost-effective.

Ultrasonic cleaners provide an excellent cleaning alternative to other traditional methods of cleaning, like spray washers. Ultrasonic cleaners can clean anything from delicate medical parts to machine parts, and everything in between.

But there are also other ways that business owners can benefit from using ultrasonic cleaners as opposed to spray washers, in relation to the cost:

1. Save on materials
Spray washers rely on large amounts of chemicals to clean stains and require operators to use protective equipment. These concerns are non-existent with ultrasonic cleaners. Cleaning with high-frequency pressure waves does not require chemical action to loosen stains. While it requires a mild detergent to help loosen the most stubborn stains, it is otherwise inexpensive when compared to the number of chemicals used in spray washers.

2. Save on labor costs
The ultrasonic waves generated by these cleaners do not need to be directly aimed at surfaces to be cleaned. The microscopic bubbles travel in every nook and cranny of the tools and parts being cleaned, assuring thorough cleaning. With ultrasonic cleaning, the parts become cleaner with less effort.

3. Save on maintenance
Spray washers may require lots of energy to operate. It has moving parts as well that require expensive maintenance -- if they cannot be maintained regularly, they would eventually lose their usefulness. Customized ultrasonic cleaners do not require much maintenance -- they don't come with moving parts -- all you have is a transducer and a bath of liquid. With very little maintenance, ultrasonic cleaning systems are guaranteed to last a lifetime.
