Why are Fuel Injector Cleaners Needed?

The function of the injector system is to supply fuel by injecting it into the engine of the machine. It ensures the required amount of gasoline to get in. Thus, the engine receives the optimal amount of fuel, which directly affects the efficiency coefficient of the car. The fuel injector, by actually delivering the right amount of gasoline to the engine and thereby increasing its efficiency, ensures that the car is moving when the driver is switching speeds.
It is very important to regularly clean and maintain the fuel injector in working condition. If the nozzles are not cleaned properly, the following problems may occur:

  • Contamination or clogging of injectors.
  • The injector valve does not open or close.
  • Fuel leaks from the nozzle.

Such situations may occur when excessive fuel or outer impurities settle on the nozzles, for example, rust. And also if the injectors are overheated or if the car has not been on maintenance for a long time. To avoid these problems, it is necessary to clean the fuel system as regular as possible. With proper care of the injector, your car will keep the gasoline consumption at the optimum level.

Best Fuel Injector Cleanser

After carrying out all work on cleaning and servicing the injector, it is recommended to change the fuel filter. This will greatly improve the quality of the fuel mixture entering the injector, and will reduce the contamination of the injectors. After flushing and cleaning your injector, the test can show high toxicity of the exhaust gas – this is normal, soon the parameters will get back to normal.

It is worth remembering that the long and high-quality work of the engine injector also depends on the timely replacement of oil, fuel and oil filters, quality spark plugs and seasonal maintenance of the car.


Perhaps, the best for cleanser of the fuel system that exists in this segment is BG 44K. When it comes to practical use, BG 44K most effectively eliminates the problems associated with the settling of rust, fuel residues and other contaminants inside the injectors.

Questions and Answers

How to Use Fuel Injector Cleansers?

Cleansers are easy to use – mix them with gasoline, keeping in mind the manufacturer’s specified proportions. A greater effect is observed if the cleaner is poured into a half-empty tank, and only then the car gets refueled.

How Does the Injector Work?

A fuel injector is a valve that, after receiving signals from the vehicle, injects a measured amount of gasoline into the engine. At the end of the injector there is a small spray nozzle, that gets the gas supplied to with a pump. Then, the nozzle sprays the fuel into the intake manifold of the engine. From there, gasoline is fed to the motor in the form of a rarefied mixture (mist), where, mixing with the incoming oxygen, creates a combustion reaction. With the absence of the injector, the engine directly absorbs gasoline drops. This not only increases fuel consumption, but also leads to a rapid wearing off of the motor. Using the fuel injection system, gasoline enters the engine in the form of a dilute mixture, which increases both – the fuel economy and the life of the engine of your car.

Injectors help to establish the correct balance between the consumption of fuel and oxygen, adjusting the fuel consumption in accordance with the volume of air flow of the car. With the injector working right, you can be sure that the petrol of the machine is consumed sparingly.

Advantages of Fuel Injectors

The main advantages of cars with fuel injectors are:

  • Control over fuel consumption. Since gasoline is sprayed from the injector as fog, you can be sure of its efficient use by the engine. The main reason why the injection system is preferable today is that the injectors do not waste any gasoline at all. And in a long run, this technology not only saves fuel, but also saves lots of money for car owners.
  • Reduction of the toxic waste amount. Injectors guarantee that the fuel gets straight into the engine of the car. Gasoline steam, mixing with oxygen in the engine, create the necessary combustion that releases less toxins.
  • Increasing of the engine power. When gasoline enters the engine in the form of drops, there is excess friction towards the motor, that causes increased loadings and makes it run out faster. When gasoline is sprayed as fog, there is no excessive loading on the engine. It effectively uses the fuel injected through the nozzle to power the engine.
