It's always the injectors' fault, isn't it? Of course not, but in case of problems with the ignition system, smooth operation of the engine, or the fuel consumption increases up the experienced drivers check the injectors first of all.

Injectors or atomizing nozzles — a structural element of the engine, namely the injection system that supplies fuel under high pressure to the manifold. The quality of fuel or gas spraying - is an indicator of the reliability and wealth of the injector. 

Atomizing nozzles can be classified by type of the method of injection: mechanical electromagnetic, electrohydraulic (diesel), piezoelectric (diesel). 

If you are conducting a diagnosis of the car, then you can see the following trouble codes connected to the injectors. The errors are:

  • P0201 - P0205 (open circuit, injector 1-5)
  • P0171 - P0175 (insufficient MDP, injector 1-5)
  • P0263 - P0275 (error correction of the feed value)
  • P0611 - P0612 (injector codes C3)

So, the problem of failures in the functioning of the atomizing nozzles is the formation of a short circuit and violations in the wiring of the system. 

As mentioned at the beginning, the symptoms can be completely different, ranging from a lightning engine check to an engine misfire. This range of problems can be caused by the ignition system, engine failures or transmission failures, etc. Therefore, to avoid problems you better to check and/or replace the injectors.

The soot and dirt clog the nozzle, thereby disrupting the force and direction of the injected fuel.

According to manufacturers, the use of the additive compound allows it to clean the injectors from the scurf. However, the quality of nozzles depends on the class, brand, model and of course, on the operation of the car. Resorting to preventive measures and conducting a quality inspection and care of the car, you will extend the life of its systems long.
