The question of the need to clean the injector is considered practically the most discussed among car owners. There is no single answer. How to determine whether this procedure is necessary for your "iron horse"?
Injectors are the main component of an injection engine. It is with their help that the metered injection of fuel into the combustion chambers occurs. There is an opinion that the nozzle becomes clogged due to the use of low-quality fuel, which may contain sand and other impurities. However, in reality, the likelihood of this is not particularly high: the fuel system has filters where the fuel is purified. The injector has the ability to clog due to the fact that heavy fractions settle on the walls of the nozzles. This mainly happens after stopping the engine. As a result, the nozzle passages become clogged, which interferes with normal performance.
How can you tell if an injector is clogged?
If your car is operated with diesel or any other fuel of European standards, then you do not need to worry about preventing the condition of the injectors. It should be mentioned that manufacturers advise replacing injectors every 120-140 thousand km. regardless of their condition.
However, in fact, the nozzles become clogged after 20-30 thousand kilometers due to the use of Russian fuel. In the cold season, the car owner begins to notice obvious problems in the operation of the engine:
- A car, for example, a vaz, does not start the first time, - Fuel consumption is growing significantly, - The gas pedal falls through, - Acceleration dynamics deteriorates, - Auto twitches when accelerating, - The performance of the injectors drops, - Exhaust becomes more voluminous.
It is to prevent these and some other problems with the car that the injector nozzles should be flushed. However, you should first diagnose the car with a specialist, since such troubles can be caused by interruptions in other systems of the car.
Nozzle cleaning options
Currently, there are several ways to bring the injectors to their normal state:
1. Adding an additive to the fuel that cleans deposits while the engine is running. Professionals recommend carrying out such manipulations as preventive measures every 5 thousand kilometers. However, it is important to know that this method is only suitable for cars with low mileage. Ideal for a new car after initial use.
2. Connection to the injector of a special device for washing. The fuel is replaced with flushing fluid in combination with gasoline and is supplied under pressure to the engine. As a result, contaminants move away from the nozzle walls and burn out in the cylinders. This method is financially costly.
3. Ultrasound. Cleaning nozzles with ultrasound is a modern way to remove dirt. The nozzles are removed and placed in an ultrasonic bath. The inner and outer surfaces and cavities of the nozzles are cleaned. This is very effective and optimal for all vehicles, regardless of mileage.
Thus, before deciding on the need to clean the nozzles, consult with a professional technician and choose the option that suits you.
