Cleaning injector nozzles

Ultrasonic cleaner for cleaning injection nozzles.

Deposits of paraffins and soot on the injection nozzles/injectors change the spray pattern and thus worsen combustion in the engine. This results in increased fuel consumption or engine failure if the injector nozzle is completely clogged.

Due to the particularly high injection pressures in the diesel engine of up to 3,000 bar, a blockage of the injector can lead to the nozzle bursting and consequential damage due to free metal splinters in the combustion chamber.

It is therefore recommended to clean the injectors after the first 100,000 km and every 60,000 km thereafter.

Cleaning the injectors with additives added to the fuel is only of limited effectiveness. With a removal and intensive ultrasonic cleaning, the nozzles are effectively freed from deposits.

Especially for this application, BANDELIN offers a complete solution that has proven itself with many users, e.g. in the automotive sector - cleaning with high-performance ultrasound. The injection nozzles are placed in a SONOREX SUPER ultrasonic bath with the biodegradable cleaning concentrate TICKOPUR TR 13 for a few minutes at 50 - 60 °C and the dirt deposits are gently removed in an environmentally friendly way. The ultrasound generates microscopically small bubbles which, when they implode, gently remove the dirt even from hard-to-reach areas of the injectors. After installation of the cleaned nozzles, they function reliably again. The service life is considerably extended by this gentle cleaning method, and time and costs are saved. Ultrasonic baths in various sizes as well as a wide range of accessories are available for a high cleaning volume.
