Flushing of injectors: additives, solvents or ultrasound

The nozzles are designed for spraying air mixed fuel, entering the cylinders of the internal combustion engine under high pressure. If the nozzle is sound and clean, the spray mixture enters the cylinder in a conical shape. If it is clogged and has a deposit, 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 car owner should not lose sight of their condition, and regular flushing of the injectors should become a must.

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

More recently, the washing of the nozzles with their own hands was not so much a priority, as the only opportunity for all drivers of road transport, without exception. Nowadays, special technologies have been developed that make it possible to carry out preliminary prevention of deposit formation on nozzles and specialized equipment, which is commonly referred to as stands where automated nozzle washing is performed.

Owners of vehicles wash them independently with additives (additives) to fuel. Nowadays, the market offers a wide range of equipment care products, including reagents, with which the pre-flushing of injectors is carried out. They need to be added to the fuel system every two to three thousand kilometers. As a result, the minor soot formed 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 preventative to prevent the formation of a thick layer of carbon. In no case can add additives, if the nozzles already have old dirt. The pieces of carbon deposit washed from the surface of the nozzle will penetrate into the filter, they will block the pipeline, they will get under the great pressure of the fuel pump into the cavity of the nozzles and finally spoil them.

Therefore, when there is already a carbon deposit on the nozzles of the nozzles, it is possible, without removing the injectors from the engine, to wash them with the solvents on the stand. At the same time, the car engine is started, and at that time the entire system is flushed, and the condition of the injectors, their operability and the spraying pattern of the fuel mixture are tested. Such a flow washing 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 washing of the nozzles will be effective, because the other two methods are no longer suitable, they will not correct the situation. In this case, the nozzles are removed and placed in a bath with a process solution through which ultrasonic radiation is passed . The caked up carbon begins to peel off and fall to the bottom of the bath.
