Nozzles are designed to spray fuel mixed with air entering the cylinders of an internal combustion engine under high pressure. If the nozzle is serviceable and clean, then the sprayed mixture enters the cylinder in a cone-shaped form. If it is clogged and has carbon deposits, then the spray pattern and the proportion of the fuel-air mixture will change, which will increase fuel consumption and adversely affect engine performance. To prevent this from happening, the owner of the car should not lose sight of their condition, and regular flushing of the nozzles should be a must.

Fuel injectors operate in a very aggressive environment. In this regard, the quality and purity of the fuel are of great importance, since very small organic contaminants, burning, settle on the nozzles of the nozzles in the form of a layer of soot. Flushing nozzles is needed in order to clean this soot. It can be done in many ways.

More recently, do-it-yourself washing of injectors was not so much a priority as the only opportunity for all motor vehicle drivers without exception. Today, special technologies have been developed,which make it possible to carry out preliminary prevention of the formation of carbon deposits on nozzles and specialized equipment, which is commonly called stands, where automated washing of nozzles is performed.

Vehicle owners wash their own vehicles with additives (additives) to the fuel. Nowadays, the market offers a wide range of equipment care products, including reagents, with the help of which the nozzles are pre-washed. They need to be added to the fuel system every two to three thousand kilometers. As a result, the slight soot that forms on the nozzles during the operation of the car is removed.

These additives are good and effective, they extend the life of the injectors, help keep the entire fuel system clean, but only as a prophylactic that prevents the formation of a thick layer of carbon deposits. In no case should additives be added if there are already old dirt on the nozzles. Pieces of soot washed off the surface of the nozzle will penetrate the filter, clog the pipeline, get under the high pressure of the fuel pump into the cavity of the nozzles and completely ruin them.

Therefore, when there is already a layer of soot on the nozzles of the nozzles, it is possible, without removing the nozzles from the engine, to wash them with solvents on the stand. At the same time, the car engine starts, and at this time, the entire system is flushed, as well asthe state of the injectors, their performance and the form of spraying the fuel mixture are tested. Such in-line flushing of nozzles in an automated mode does not take much time. It is effective at the stage of medium pollution, so it is recommended to use it regularly.

If the nozzles are already coked, then only ultrasonic cleaning of the nozzles will be effective for them, because the other two methods are no longer suitable, they will not correct the situation. In this case, the nozzles are dismantled and placed in a bath with a process solution through which ultrasonic radiation is passed. The coked soot begins to flake off and fall to the bottom of the tub.
