A person buys a car and thinks that he will serve for a very long time. Naturally, the car owner knows that it is necessary to care for and maintain responsible nodes. But even a fully serviced equipment begins to malfunction - jerks are felt during movement, dips appear when you press the accelerator pedal, acceleration is completely different, fuel consumption makes you literally shed tears. And at the same time, everything is normal with the machine - the “Check engine” light on the dashboard does not light, there are no oil leaks in the engine compartment. What is the reason?
And the reason for this car behavior is a polluted
fuel system. And it gets clogged not with simple particles (for example, sand), but with something else - with substances contained directly in the fuel, which filters do not trap. To solve this problem, you need fluid to
flush the injector. There are many types of such drugs. We learn how to choose a quality product, what types of these mixtures exist and their features.
Why nozzles get clogged
Gasoline is a heterogeneous fluid. This is a mixture of light and heavy particles of hydrocarbons. Naturally, light fractions burn better and faster. Heavy particles burn much longer, and as a result - soot on the elements of the motor. But besides hydrocarbons, gasolines contain other substances. These are various resins, impurities, additives and other additives. It is these substances that, as they move along the intake tract, clog everything that they are dealing with. And if in the fuel lines these deposits do not lead to anything special, then in the hot power unit the cylinders, piston group, and also nozzles suffer.
The nozzle is a special device that injects fuel into the combustion chambers of the engine. This element affects how gasoline will perform its task. If the nozzle is clean, then the fuel is sprayed like a deodorant in a spray can, and the feed is conical. During operation, the nozzle heats up, and deposits begin to accumulate on the working part. As a result, the torch changes its correct shape, and the fuel is poorly atomized or is supplied by the jet, which will necessarily affect the performance of the engine.
Signs of dirty injectors on injection engines
Hence the problem that car owners face is increased fuel consumption. The computer tries to compensate for poor combustion by the amount of feed. There is also a decrease in dynamics and failures. The fuel burns unevenly, thereby not providing the necessary characteristics for the engine. How to fix the situation? There are two possible ways - to purchase special liquids for washing injector nozzles or use ultrasound.
Ultrasonic treatment
This solution is very effective, but there are several problems. The first thing to remember is that only nozzles lend themselves to ultrasonic cleaning. The remaining parts of the fuel system cannot be cleaned in this way. And this method is not always suitable. For example, ultrasonic cleaning is contraindicated in nozzles with ceramic parts. The fact is that this material is destroyed by exposure to ultrasound. Ceramic nozzles can be found on vehicles with direct injection.
In addition, there are other difficulties. For cleaning, it is necessary to dismantle the nozzle and lower it into a special bath. Replaceable nozzle filters and sealing parts. These dismantling operations significantly increase the cost of this procedure.
Flushing the injector through the fuel rail
So, a special tube is attached to the ramp, through which liquid is supplied under sufficient pressure to flush the injector. But all this can be done only on professional equipment. Only high-quality liquid for flushing the injector is used. The price of such a procedure is quite high. The advantage of this option is that you do not need to remove the nozzles, but you will have to dismantle the fuel line and replace the spark plugs.
Do-it-yourself flushing
This is the third option. This is where the liquid for flushing the injector into the tank is purchased. The disadvantage of this method: the drugs can not cope with serious contaminants and are suitable only for maintenance work on relatively new machines. But the modern car chemistry market offers effective compounds that help give the motor a second wind.
Classification of liquids for cleaning power systems
The injector flushing fluid, which is produced by modern manufacturers, can be divided into two main types. The first is a drug that directly affects all elements of the injector. These mixtures are injected directly into the nozzle or any container designed for this purpose. The second type - various additives with which it is necessary to flush the injector. They are poured into the tank of the car.
Then the drug enters the injector and cleans the nozzles. There are a huge amount of cleaning fluids on sale. There is no special sense in comparing them - they have various properties and qualities. They are also perceived differently by the consumer. Someone carefully monitors the machine, and then these mixtures will be good. For those who do not service the car, but want to get the result immediately, they will not work.
Wynns injector flush fluid: quality and warranty
This is how the manufacturer delivers this drug. Experts argue that this tool is no less effective than expensive Japanese liquids. This mixture is made in Belgium. The company has been on the market for more than five years. Among the main advantages of the Belgian drug is the composition, which uses a number of strong solvents. Due to the fact that the manufacturer worked very carefully on the composition, Wynns injector flush liquids begin to act from the first minutes. Almost immediately, reactions start during which the drug dissolves any impurities, regardless of their thickness. Among the main characteristics, one can single out the quality of cleaning not only the injector, but also valve seats, piston system parts, and combustion chambers. An advantage is the absence of the need to dismantle these parts.
Washing injector nozzles with Vins products helps not only to clean the elements, but also to restore the characteristics of the torch, as well as bring the nozzle to the optimal intake period. Such a composition is an ideal choice for cleaning intake valves. Injector processing helps eliminate knocking and greatly improves the sound of engine operation. Professionals choose Wynns injector flush fluid. Its price starts at 500 rubles per 1 liter.
How to work with Wynns fluids
First of all, you need to start the engine, then get the fuse for the gas pump - this relieves the pressure in the fuel system. Further, the terminals and the fuel supply hoses are disconnected from the nozzles. Then remove the fuel rail and O-rings.
After all these steps, access to the injector is opened. Now it remains to figure out how to flush. The technology is to ensure that the nozzle does not let fluid through when the valve is closed, and vice versa. For work it is recommended to use Vins cleaners and devices for supplying fluid through nozzles. An ordinary plastic bottle is suitable for this. It is connected to the container in which the liquid is located, and to the inlet on the nozzle. Also useful are two wires from the battery, which are connected to the terminals on the nozzle. Now you can start flushing. Under pressure, fluid is injected into the injector. In this case, the nozzle must be alternately closed and opened. This procedure is performed until a normal flare is obtained. Then the injector is washed again.
Many car owners managed to try these liquids to flush the injector. The reviews confirm that if you did not care for the car, then nothing will help. But in general, everything that is offered in the modern market is of good quality and affordable prices. When buying such a drug, it is important to see that it is suitable for a particular car and injector.
How to make do-it-yourself wash liquid
Many car owners are sure that you can make an effective liquid for washing the injector with your own hands. Yes, indeed, there is an opinion that the injector can be cleaned with means for washing carburetors. In this case, you do not have to visit the service station and pay for the expensive procedure. However, in the case of using "artisanal" drugs, there is an option that the engine will not recover.
There is a serious likelihood of improper selection or preparation of a cleaning mixture. There are also risks of damaging engine parts or the fuel system. Even Wynns fluid is quite aggressive, and homemade products can be completely deadly for the fuel system. There are also no guarantees that the process will be of high quality.
Summary
You can clean the injector with your own hands in the garage, using a self-prepared preparation or a factory mixture. Each owner is free to choose a way to care for the car on their own. But experts recommend using the services of professionals.
So, we found out how to clean the car injector with your own hands by washing. Such manipulations are often not recommended, since aggressive substances can worsen further engine operation due to incorrect fuel injection.
