Engine nozzles COMMON RAIL. Sometimes you need to clean, repair or replace. To do this, you need to remove them from the engine. As I did it, I will tell you in this article.
Before you start. Important.
Some nozzles have correction codes in the amount of fuel injected. Therefore, before removal, it is desirable to find out whether their nozzles have them. If you have or not there is an opportunity to get such information, it is better to remember which nozzle where it was, it would not be worse, and if there are no such codes, the places of installations are not fundamental, as in my case.
Looking under the hood, we most likely see the plastic dust-heat shield.
It holds on four screws. We unscrew them, remove the casing. Now we see the engine itself.
First, open the relay box and fuses under the hood and pulling relays fuel pump. This is to ensure that the diesel fuel does not flood the engine and the floor, if you suddenly need to turn on the ignition.
Then turn off the nozzle electrical connectors.
Withdrawn locking brackets, which fix the reverse hose connections.
Perform the removal of nozzles on the injection car VAZ 2109 is not rare. You can contact the car service where everything will be done for your money, or to spend your own work with your own hands, having received invaluable experience and saving an impressive part of your own budget. The choice is yours.
Location
It is impossible to start a conversation on the instructions for removing the nozzles, without talking first about the location of the desired object.
Car nozzles VAZ 2109 are located on the fuel ramp. There are 4 pieces of them. This is due to the fact that each nozzle spray fuel to one separate cylinder. Since nine has four cylinders, we conclude about the logicality of the number of nozzles.
When replacement is required
There are several signs that indicate the need to at least withdraw and check the condition of fuel sprayers. Next is the decision to clean or replace items.
Pay attention to the behavior of your car and the engine specifically. They will prompt you if something is wrong with nozzles. It can appear as follows:
- The engine generates smaller power, does not feel the same acceleration efficiency;
- For bad work engine, lack of power, all the same fuel consumption increases;
- Bad start is not a rare sign of the failure of the nozzles;
- If the engine does not keep idle, the sprayers may well be the cause;
- In exhaust gases, the number of toxic components increases;
- At idle rises.
Do not rush to immediately acquire new nozzles, because the cleaning of older does not rarely resume their performance, returns the former stable functionality.
Removal and replacement
Now we will tell us specifically how to remove and replace the old nozzles that have lost their suitability to new units.
The dismantling process of each of the 4 injectors is identical, because there will be no difference in the process.
Perhaps the most problematic phase of replacement or cleaning the nozzles is dismantling the fuel ramp. Therefore, we will describe separately how this node is removed.
The fuel ramp is a bar on which nozzles are installed. It is fixed by a pair of bolts on the inlet tube. To the left of the ramp is a fuel pressure control unit. To remove it you need:
- Disable the minus terminal from the battery. Short circuits are not needed by anyone;
- Reset the pressure in the fuel line;
- Remove air filter and disconnect the hose of the intake pipe, after which dismounting the vacuum pressure regulator hose;
- Disconnect the wires of the wires from the idle sensor. For this, the plug lock is simply pressed, made of plastic;
- Disconnect the block with wires that are moving from the nozzles;
- Turn off the plum hoses and feed from fuel pipes;
- Unscrew the pair of fastening bolts on which the fuel ramp is attached to the inlet tube;
- Fuel tubes are held by a special holder, to remove which you want to unscrew one fastener screw;
- Remove the fuel ramp by shifting it along the axis of fuel sprayers. So they will come out from their landing position on the inlet tube;
- The assembly is performed in the reverse order.
Please note that the fuel ramp bolts are the washers, which should be returned to the place during the reverse assembly or replace the new ones.
- First of all, remove the fuel ramp from your car.
- Next, the ramp is placed on a flat surface, after which the wire block turns off from the damaged nozzle. To remove it, it is required to compress the spring fastening bracket, and then disconnect the block.
- With a screwdriver, slide the metal retainer to the fuel ramp. It serves to fix the fuel sprayer. Many for some reason remove the retainer completely. There is no need for this. Just slide a little to the side.
- Take the nozzle in your hand and shook a little on the sides. So it should come out of the fuel ramp without unnecessary problems.
- In parallel, be sure to check what the current state of the fuel sprayer sealing rings.
- Similarly, a sealing ring of spray element is checked. To do this, you need a screwdriver to make both rings and see if they were not caught.
- In the case of fuel injectors, changing sealing rings when replacing the sprayers themselves are not needed if they are in good condition. Only if you are going to reuse them, be sure to lubricate the oil rings before installing. Motor, of course.
- When the nozzle is removed and the rings are replaced (or old old), you can start installing new devices. The procedure in the reverse sequence is performed.
- Insert the sprayer into the hole on the fuel ramp, fix the retainer.
- Return a block with wires to place, set the fuel ramp on your rightful place.
Not always the replacement of nozzles is the only and rational way to restore the performance of fuel sprayers. Try to clean them. This is not a difficult thing, but the savings come out impressive.
Cleaning
There are two ways to clean the fuel sprayers, each of which has its own nuances. Choose yourself what more like it or more accessible, taking into account the available funds.

Both operations occupy approximately 2-3 hours, but cost several hundred rubles. This is ten times cheaper than replacement and about the same amount more affordable than the service station.
In small spare parts, which have a huge influence on engine functional abilities, are nozzles. As a result of work, they have the property clogging, which leads to the need for their cleanings, and sometimes replacements. However, the removal of the nozzles from the engine is not such a simple task. Specialists of our company Diesel-Sever will help you to cope with it.
Why the dismantling of nozzles is so complicated
Between spray guns and candle there are some gap. Over time, moisture falls into it, which causes the sticking of the injectors to the cylinder block. This process leads to the fact that it becomes almost an integral part of it. Dismantling the nozzles in this case is very difficult.
On the diesel enginesSuch a problem is even more relevant. As a result of the exercise of copper washers under the influence of combustion products, practically welding sprayers to the engine block occurs. Removing diesel nozzles by independently without damaging them, in this case it is almost impossible.
When trying to remove fuel injectors, it is extremely important to remember that the risk of damage to the engine itself is great. Therefore, it is unacceptable in such cases to try to remove them alone. To remove the injectors, you need to contact the specialists.
What to do if she bought?
So that such a trouble did not occur, it is necessary to monitor the state of the engine and its details, to dismantle the nozzles every 50,000 kilometers. Lubricate them before installing non-stick paste, and clean their threads. However, if such prevention did not help, and they still bought, then you need to immediately access qualified specialists, that is, to us.
We carry out fast and high-quality removal of diesel nozzles. For many organizations, a serious problem is the removal of 4 and 5 nozzles in such cars like Ssang Yong Cayron, Rexton, Action, however, we produce their dismantling even without the need to remove the head of the cylinder block and the hood.
Such wide possibilities of our organization are associated with qualified personnel and the newest functional technical base, which we possess. Turning to us, you can remove fuel injectors, guaranteed to keep the integrity of the cylinder block. Moreover, thanks to innovative approaches, after their dismantling, the likelihood of restoring these parts is great.
There are tens of thousands of automotive in Russia filling stationsHowever, not all of them can boast the presence of high-quality gasoline that meets all modern standards and standards. Often in the fuel are not only particles of dirt, but also various impurities (phenols, sulfur compounds, acids, lead, etc.). In addition, poor-quality gasoline is often characterized by low octane number. All these factors extremely negatively affect the operation of the engine as a whole, and the stability of its individual components in particular, significantly reducing the life of all motor nodes. That is why every car enthusiast must have an idea of \u200b\u200bhow to remove and clean the nozzles on the VAZ 2110. Do not immediately begin the execution of these works.
To clean the nozzles must be resorted only as a last resort, when there is no doubt unstable work Engine vehicle.
Symptoms indicating the need to clean the nozzles on the VAZ 2110:
- There are problems with the start of the engine.
- Increases flow rate fuel mixes.
- Drops the power of the engine thrust.
- While driving in winter time Year of the car periodically moves jerks.
- Refuses one of the engine cylinders (the effect of the trim), etc.
The cleaning of nozzles must be carried out in the case of the appearance of one or more symptoms described above.
Options solving the problem
Today, every vehicle owner can stay at one of the three possible options for cleaning nozzles:
- take advantage of automotive chemistry;
- resort to the service station maintenance;
- self remove and clean the nozzles on the VAZ 2110.
In our article we will end in detail exactly the third version of the issue of the issue. Self cleaning is safer and effective compared to the effect that comes after applying automotive chemistry. The economic benefit from cleaning the nozzles with their own hands is also an obvious fact if it takes into account the rates operating at the maintenance stations. It is recommended to conduct this procedure only if you have at least a general idea of internal device cars. Otherwise, cleaning the nozzles is advisable to trust the specialists.
- Before starting work, you need to make sure that the engine of the vehicle has cooled.
- Then from the fuel pump you need to disconnect the power wires for the complete de-energization it.
- The next step is to maximize the pressure in the power supply system. To do this, the engine must be started, after which it will wait until he himself stalls on idling. This action should be repeated several times until the motor stops responding to attempts to start it.
- Now you can proceed to dismantling the fuel ramp. To do this, it is necessary to pre-de-energ it, disconnect the fuel supply hoses from it and disconnect all electrical devices from it (idle and pressure regulators, the position sensor adjusting the air into the engine ( throttle valve)). After that, with the help of a hex manner, you need to unscrew the two fastening bolts and gently dismantle the fuel frame with nozzles. During the removal of the frame, it is necessary to monitor the lack of overcasts that can significantly complicate the dismantling procedure.
- Next, you need to start removing the nozzles. To do this, you need to disconnect the fastening staples that lock the electrical connector (connector) and the fastening bracket that holds the nozzle at the seating area. In order to avoid dirt from entering the details, removed nozzle it's best to gently put on a dry rag, and their planting To cover something.
- Rubber sealing rings before the procedure is recommended to remove, and after the completion of cleaning, install new ones. The cleaning of each nozzle is best to start with the purification of its nozzles from various deposits. It should also be paid to the funk-shaped surface on which coke-shaped resinous sediments can accumulate.
- After that, you can move to the cleaning of the fuel mixture channel. For opening electromagnetic valve Fuel supply requires a power source, preferably not exceeding 5-7V. To do this, you can use an adjustable stabilized voltage source or charger from mobile phone. Suit I. accumulator battery In this case, in this case, the stress on the nozzle should be supplied through the incandescent lamp that performs the function of the current damper to exclude the likelihood that the nozzle winding will be burned.
- The supply of electricity is carried out through two wires, into the gap of one of which you need to install the button, closing and opening the network, including and turning off that we imitate the operation of the nozzle in the engine under the action of pulsed electricity.
- You can use a can be used as a cleaning fluid to supply the cleaning fluid to the nozzle channel in which the liquid is located intended for cleaning the carburetor.
- For a sealing connection of the nozzle, the nozzle with a nozzle can be used a rubber tube, which must be securely fixed using a plastic clamp or any other available mounting on the nozzle of the spray and on the nozzle.
- When everything is ready, you can start feeding electricity to open the nozzle, in parallel by pressing the canter to supply the washing fluid. After a while, the torch of the jet of the cleaner exiting the fuel sprayer should become uniform and well distinguishable, which indicates a successful removal of Nagara. The cleaning procedure is considered to be made.
Expected effect
If the nozzle cleaning procedure was carried out correctly, the fuel consumption will decrease, the engine power will increase, a smooth idle turn will appear, and the start of the cold motor will occur without any difficulty.
Helpful information
Practice shows that if they were replaced on the nozzles of other manufacturers (even well-proven brands, the volume of the fuel mixture consumed can significantly increase.

Looking for instructions for replacing nozzles in the engine on the Injector cars "Samara" family? If yes! Then in this case, we will review today with detailed instructions By replacing the nozzles. For clarity, the stroke of the nozzles will be supported by photographs, and at the end of the article you will find a small video clip in which it is said about how quickly you can remove the nozzles from the car.
Summary:
Where are the nozzles?
The nozzles themselves are located on the fuel ramp in the amount of four pieces, that is, one nozzle spars the fuel strictly to one cylinder. Below is a photo of that fuel ramp and nozzles that are located on it. Nozzles are shown in red arrows.
When do you need to change the nozzles?
They are subject to replacement if:
- The engine of your car began to go worse.
- As well as if when the engine is running, the fuel consumption has risen.
- In case of malfunction nozzles, the engine is usually starting to start badly.
- After launch, the engine can also be unstable to keep speeds at idle.
- An engine is still possible at your car, at idle will start working on larger speed.
- And in conclusion, with defective nozzles in the exhaust gases, the content of toxic substances increases.
How to replace nozzles on VAZ 2108-VAZ 21099?
Removal:
Note!
All four nozzles are removed and installed identically, so for clarity we will show the removal of only one nozzle!
1) At the very beginning of the operation, remove the fuel ramp from your car. (How to remove the ramp, see Article: "")
2) When the ramp is removed, put it on a flat surface and then from the nozzles you need disconnect the wire block.
Note!
In order to disconnect the wire block, squeeze the spring bracket which is secure and only after that disconnect it!
3) Now with a screwdriver, move the metal retainer in the direction of the ramp that secures the fuel injector.
Note!
Fully removing the fixator with the ramp is not necessary, it is enough just to shift it into the sidel!
5) Check in what state is the sealing ring of the nozzle body, and the sealing ring of the spray part of the fuel injector, for this:
Taking a screwdriver into the hands, make it up with it both sealing rings and check their condition.
Note!
If the rings are in good condition, then in this case they can not be thrown out, but to leave on the margin and further use on the new nozzle. Before installing old rings, be sure to lubricate them motor Oil!
Installation:
Installing new nozzles occurs in the reverse order, that is:
1) First, the state of the nozzle sealing rings is checked.
Note!
The status of the rings is verified only if you are going to install a used nozzle on your car!
3) And in completing the fuel nozzle, the wire block is connected, and after the connection, the fuel ramp is installed in its place.
