The most common problem with injection engines is contamination during operation. Therefore, every fifteen to twenty thousand kilometers of the car, it is necessary to clean the injector and nozzles. Due to the high temperature in the engine after it is stopped, gasoline does not completely disappear, but is partially deposited on the walls of internal parts. This can seriously damage the operation of the motor. Is it possible to flush the injector with your own hands?

To clean it from dirt, there are two ways: liquid flushing and ultrasonic nozzle cleaning.

The easiest way is liquid flushing. True, this method is very doubtful in its functionality. It consists in the fact that a special cleaning liquid is poured into the fuel tank. However, there are doubts: whether all parts of the fuel-motor system will withstand the action of these fluids and what is the effectiveness of this entire procedure. Ultrasonic washing is the best option, but you can't do without special equipment. Such cleaning of injectors is carried out only in specialized services.

Cleaning the injector yourself

You will need electrical tape, a 12V bulb, a half meter hose, a doorbell button, a couple of spray canscarburetor cleaner (spray).

  • First you need to remove the injectors themselves. Disconnect first

    battery terminals and wiring. Before removing, it is better to write down or somehow mark which wire is connected where.

  • Next, we relieve the pressure in the fuel rail. This is done very simply: there is a special bolt on the ramp, under which you need to put some small cloth, and then slightly unscrew the bolt so that fuel begins to ooze. When it stops flowing, then you need to tighten the bolt back - the pressure is relieved. After this procedure, we unscrew the screws securing the fuel rail and injectors to the manifold, and remove our entire structure.
  • Disconnect the injectors from the ramp.
  • The nozzles are arranged in such a way: on one side there is a supply channel, and on the other there is a sprayer, which may turn out to be a

    covered with a brown oil coating. Some of these parts have a strainer on the side of the channel, which should also be cleaned.

After that, it is necessary to assemble the structure that will clean our nozzles. To do this, we securely connect the canister tube to the injector feed channel. Sometimes here you have to use electrical tape or even make an adapter from a hose.

Cleaning the injector:

  • Next to collectan electrical circuit with which we will clean the nozzles. So, with one wire we connect the “+” of the battery and the prepared bulb and the “+” on the nozzle. The second wire is “-” of the battery with a doorbell and “-” of the nozzle. After that, we press briefly on our canister connected to the nozzle and create some pressure, press the bell button - the nozzle opens - and a small uneven flame flies out of it. We continue the procedure until the flame becomes uniform.
  • After cleaning all the nozzles, we assemble them in reverse order.

This completes the cleaning of the injector. After the procedure, turning on the ignition to increase the pressure, check all connections for leaks. Tighten everything if necessary. If this does not help, then you will have to change the sealing materials to new ones.

When the leak tests are successful and the engine is running smoothly, you can be glad that you cleaned the injector correctly.
