Flushing of injectors without removal from the engine by their own hands: step by step instruction and recommendations

Many novice car owners are often asked to clean the injectors in the injector engines. The question is whether it is possible to clean them independently or it is necessary to apply to SRT specialists. Also, many people are interested in such a procedure as flushing the nozzles without removing it from the engine. Let's try to understand this question.

Operation of dirty nozzles

If the elements are clogged, then this can be felt by the reduced specific power of the car engine. Then detonation will occur at the moment of speed dialing. Particularly clearly the symptoms of contaminated jets are expressed at idle. The operation of the motor becomes unstable, the start of the power unit deteriorates, and the fuel consumption increases. The exhaust becomes more toxic. Diagnose the work of the nozzles is best on the SRT.

If on diagnostics experts have revealed that the main reason is injectors, then they must be washed. There are options when cleaning elements are removed. But it is also possible to flush the injectors without removing them from the engine. For those who will do this with their own hands, it is better to choose the second option. Naturally, if you disassemble the motor and dismantle the parts, the process of cleaning them is much easier. But this is not always convenient.

Diesel Injectors

In such a motor, the nozzles operate at higher pressures and higher temperatures. They are hammered more often. But these methods of cleaning are not effective for them. It is not suitable to clean the injectors without removing them from the engine. Diesel clean without removing - just inefficient. It is necessary to disassemble, remove, diagnose on the stands.

Causes of pollution

Flushing the injectors is the operation that any engine needs.

Sooner or later the owners of all, and even the most expensive cars will have to go through it. Knowing the main sources of pollution, you can maximally delay the moment when the problem can be solved only by washing. The main cause of blockages in the nozzles is low-quality fuel with a large volume of heavy elements. They are dissolved in fuel and easily pass through any filters. When the motor is stopped, all these elements settle on the nozzles. And the lungs - immediately evaporate.

Methods for cleaning injectors

Today there are two effective methods for cleaning elements. To choose the one that will be most effective, you will have to study both options. So, the washing of nozzles on special stands is very popular.

To do this, use special cleaning liquids. This method is quite effective. But in the case of cleaning old and very dirty nozzles, he will not give a result. Ceramic mechanisms are effectively cleaned on the stand. Still use and processing by means of liquids. In this case, it is possible to flush the injectors without removing them from the engine, or with removal. But that's not all. Below we will consider one more, no less popular method.

Method of cleaning with additives

It is considered to be the simplest. So, you just need to add a special additive to the gas tank with detergent properties.

These fluids are manufactured by all self-respecting manufacturers of auto-cosmetics. If the task is to clean the entire engine power system, then it is necessary to purchase a liquid for washing the injectors. One 0.5-liter bottle is poured into 50 liters of fuel. Thus, not only the nozzles are flushed without removing the engine, but also all the components of the power system. This includes a fuel tank, a pressure regulation system, a gasoline pump and injectors. When choosing this option, it is worth considering that the method involves certain risks. All contaminants, deposits and other substances that have been washed off with additives from the tank and the fuel line can further clog the valve in the pressure regulator.

Therefore, such treatment may be appropriate only in the case of preventive measures. This is not the most effective flushing of the injectors without removing it from the engine. The feedback of those who did it was rather negative. Another option is flushing with the help of special systems for supplying the washing liquid. The process is carried out with the engine running, and it works on a washing solvent. This method can be considered quite effective. The result is in most cases evaluated as positive.

Cleaning without removal: preparation

Most car enthusiasts try to fill in the washing liquid in the tank - this is a mistake, and so do not need to. During cleaning, the motor must be disconnected from the mains supply system. It is important to remember that there is pressure in the fuel rail. This flushing of the injector (cleaning of the nozzles with your own hands including) involves the dismantling of the hoses. Therefore, you need to work as carefully as possible.

Next, you need to prepare a temporary power supply system for the engine. For this, a plastic bottle is suitable. It is poured into a prepared cleaner. For a motor with a working volume of 2.5 liters, it is necessary to fill 1 liter of the substance. You can use the liquid at the rate of 100 gr. For 0.5 liters of engine capacity. Further in the bottle also add a little fuel. Pour half of the cleaner. Then, the hose is put on the neck of the bottle and tightened with a clamp. The branch pipe must be cut into a separate, pre-prepared gasoline pump.

Cleaning process

Then they start and warm up the power unit. Also, remove the main fuel pump fuse. There will be several starts. So will the pressure in the fuel system drop. Remove the hose, which supplies fuel to the injectors, and in its place is installed just assembled construction. Demonstrate and with "return" (it "jam"). Then include a separate gasoline pump and check the tightness of all connections. If everything is in order, then you can proceed to the main part of the process. The engine is turned on and allowed to run for about 5 minutes. After that, he should "rest" for a few minutes. During this time, the cleaner will soak all deposits. Then the engine starts again. This time he is allowed to work for about 30 minutes.

This time is enough for all the fouling to burn out. All half an hour the motor should work on the canvas. You can sometimes raise the speed to 2.5 thousand. After the end of the process, the system is disconnected and the nominal power system is connected. Now you can start the engine and leave it for 10 minutes. During this time, the remaining cleaner will burn out. At the same time you can check the tightness of all connections. Then the engine is muffled, new candles are installed. Erase the errors of the electronic control unit, if any. It is possible to carry out additional diagnostics and make sure that the power unit is working as expected. Is the washing of nozzles effective, made with your own hands? Yes, it is quite effective. Moreover, it gives a result in the Russian reality, when it needs to be done every 20 thousand km.

Folk methods

Do not dwell only on these methods. Some car owners like the way additives work. Others say that they pour a little kerosene into the tank, and they do not know about such problems. Still others say that the use of additives is a lottery, and not the washing of injectors without removing it from the engine. Advice from experienced car owners confirm that the most effective way is cleaning with a bottle and a separate gasoline pump.
