The presence in the fuel of various dirt and other impurities makes the process of cleaning nozzles in fact inevitable. It is not rare after forty thousand kilometers of mileage nozzles requires washing, and sometimes before. Many car owners in order to save preference to self-cleaning nozzles. How to do - read further in the article.

VAZ fuel injectors, signs of contamination of nozzles

It is possible to understand that the nozzles are contaminated, it is possible on the behavior of a power unit, namely:

1. Dips in the operation of the motor.
2. The engine troit on the cold.
3. Increased exhaust toxicity.
4. Large fuel consumption.
5. Fell the power of the power unit and so on.

Nozzle cleaning, which gives cleaning nozzles

The difference in the behavior of the motor after cleaning the nozzles directly depends on the degree of contamination. The more the nozzles were contaminated, the better there will be an effect in the end. As a rule, the power of the power unit increases, the fuel consumption is reduced and different problems associated with the incorrect operation of the motor disappear. Starting a cold engine will become easier, and idling - more even, turns at the cold start will immediately rise to normal.

Cleaning nozzles using additives in gasoline, good or not

There is no unambiguous answer to this question, since this is the case of everyone. Some prefer to clean the nozzles of ultrasound, others dismantle them and clean themselves, considering that this is the most effective way, but the third give preference to clean the nozzles by additives into fuel. The modern market offers a huge number of different additives in gasoline for cleaning nozzles, and each vehicle has its own degree of contamination, different mileage, the quality of gasoline, and so on.

Tools, fixtures, consumables for work

You will need:

1. Sealing rings on fuel pipes (four pieces).
2. Rubber rings nozzles (eight pieces).
   
3. Tumbler (12 V) and light bulb (10 W).
4. Electrical wire (two meters).
5. The syringe, the output diameter of which is ten millimeters (ideal for it, if you do not dismail the sealing ring from the nozzle).
6. Rubber tube.
7. Fluid for washing nozzles - solvent, vens, carburetor cleaner and so on.
   
8. The key to "8" in the form of a rhombus.

Preparatory work, how to get to nozzles, step-by-step instructions

Before proceeding to the disassembly of the engine, it is desirable to reset the pressure in the fuel rape, for which we disconnect the wiring harness from the fuel pump. Next, we start the motor and we are waiting for a while until the power unit stalls. It must be done so many times until the vehicle ceases to start.

Then we do the following:

1. We dismantle the nozzle that goes from the air filter.
2. Disconnect the wiring harnesses of the nozzles.
3. Next, disconnect the harnesses of the idling regulator and the throttle sensor.
4. Disconnect the white vacuum hose from the pressure regulator. Act carefully, because antifreeze may fall.
   
5. Then you need to unscrew the fuel supply tubes in the ramp. Be very neat, fuel can be fuel.
6. For convenience, remove the gas cable.
7. Now you need to unscrew the plates fastening bolt, which presses fuel hoses.
8. To remove the fuel ramp, you should unscrew two bolts using a hexagon to 8.
9. Next, dismantle the ramp with nozzles - it is removed tightly, since the nozzles are very tightly sitting.
   
10. The design is raising up and fixed behind a wiper leash using a wire segment. On the 16-valve engine to remove the ramp more complicated than on an 8-valve.
11. To remove the nozzles, we disconnect the staples that hold the electrical connector, and then the bracket holds the nozzle. It is advisable to put a rag because the fuel is poured, and the nozzle should not be laid on the dirt.

Cleaning the nozzles, the phased running of the swelling

It is advisable to cover the holes in the ramp so that the lacquer does not drop there any foreign object. Now go to clean the nozzles. Since at 12 V and 3 W, the nozzle does not open, it is necessary to use 12 V and 10 W, which will require a lamp serving as a damper. Connector for nozzles connect to 12 in the lamp and microswitch.

Since the nozzles cleaning will occur under pressure, all fasteners should be strong enough. Collect the device to be supplied to the nozzle cleaning fluid by different methods. For example, you can glue the rubber tube in the sprayer head with a thermoclate / clamp or use the syringe, which is most convenient.

Injectors cleaning technology:

1. We dismantle the sealing rubber ring from the nozzle.
2. On the knuckle shank we dress the rubber tube.
3. We connect the wires to the car's battery - the polarity of the connection can be any.
   
4. Holding a design in the hands, you must click on the cylinder head until the hiss stops and the pressure is not balanced.
5. The nozzle is directed to the side and click on the button.

The cleaning procedure must be repeated two or three times for each nozzle. If nozzles are really contaminated, then the first portion of the fluid will change the type of jet coming out of the nozzles.

What needs to be replaced when cleaning nozzles

After cleaning, it is necessary to replace old rubber seals, as well as the grid (if necessary). It is advisable not to lubricate the rubber bands with oil. The injectors will take about two to four hours of time.

The advice of the pro, what kind of spraying the nozzles is considered the norm

Spraying the nozzles should be clearly distinguishable and uniform. The nozzle cleaning procedure must be performed until it becomes such.

Cleaning nozzles, how to clean nozzles without removal

It is worth saying that cleaning nozzles without dismantling from the car is not a complete wash, but only preventive measures. In most cases, this event helps, but the results are only predicted, and the effect may be short-lived, since the networks have not been dismantled and there is no visual control of work, as well as testing the balance of performance, but nevertheless, this method works.

In addition, after such cleaning, the candles immediately come into disrepair, as a result of which it is desirable to exercise this event on spare candles that have already worked out. At the service station, this process is as follows:

1. Connects construction (self-made or acquired) for pressure supply.
2. The pressure rises to 3.2 atm.
   
3. The motor starts ten minutes, after another ten minutes he is given to stand.
4. Next again, the power unit is created and, podging, burn the entire cleaner. The smell of exhaust, when working, resembles the smell of kebab.
5. Changes of candles that were covered in Nagar. The whole procedure lasts about an hour.

How to wash the nozzles on your own without dismantling with the help of remedies:

1. The air intake corrugation must be disconnected from the receiver.
   
2. In the ramp you should reset the pressure.
3. Next, you need to disconnect the fuel line from the ramp.
4. Then we take the carburetor cleaner and spray in the ramp.
5. By Ramp, connect the pump hose (electrical, foot, manual) or connect the cleaner cylinder and ramp hose.
6. Next, we pump the pressure at least 2 atm.
   
7. Now you need to insert into the jack of the nozzles prepared connector with wires.
8. Now, several times on the nozzle we bring meals briefly.
9. Connect the next nozzle.
10. Process repeat for each nozzle.
11. Clean until the cylinder is over with a cleaner.
12. Disconnect from the ramp hose.
13. We close the hood and leave the car until the morning for venting / dying.
14. In the morning connect the air and fuel line.

Nozzle, how to clean the nozzles ultrasound, pros and cons of this method

The benefits of this method is rather contradictory. Some believe that ultrasound kills the nozzles, because it destroys the mesh, others claim the opposite - that this is the necessary event when cleaning the nozzles and that it is mandatory to be combined with their washing when dismantling. According to some specialists, ultrasound has an impact on the ceramic components of the nozzle, so the period of influence must be reduced to a minimum. Another disadvantage of the ultrasound method of cleaning is a high cost.
