Fuel Injector Nozzle DLLA154S284C2

The most common problem in the operation of nozzles is their banal contamination. Therefore, in order to restore their performance and return the nominal performance of the nozzle, it is enough to clean it. This can be done in two ways - without removing it from the internal combustion engine (by adding a special cleaner to the fuel) and in the removed state (by passing the cleaner through a separate nozzle or ultrasound). The following methods are used for cleaning:

• mechanical;
• ultrasonic;
• with the help of chemicals.

Here we will only briefly touch on a few methods, since often additional professional equipment is needed to clean nozzles.

In addition to the above methods of verification, one can also mention checking the toxicity of gases and opacity - a low level of CO during gassing is a sign of poor injector performance. this method is practiced in some service stations, as a control of the operation of the internal combustion engine. Since both certain knowledge and equipment are needed, we will not consider it as one of the options for self-diagnosis.

you also cannot ignore and pay attention to checking the injectors for correcting fuel supply and lambda, but here the situation is the same as with toxicity, you will need not only diagnostic equipment, but also be able to understand all the numbers that diagnostics will show you.
