How often do you change the fuel injector?

According to the car condition and the quality of fuel added at ordinary times, generally speaking, it is recommended to clean it once every 20 ~ 30 thousand km. The car is in good condition and the fuel quality can be extended to about 40,000 ~ 60,000 kilometers. When the injector is slightly blocked, it also has a certain impact on the vehicle condition.

Necessity of cleaning

After the fuel system works for a period of time, the carbon deposit and colloid formed by combustion will adhere to the fuel nozzle, making the fuel nozzle stick or even block. However, impurities and dust in air and gasoline can also cause oil circuit blockage or blockage, and finally form carbon deposits and deposits on the fuel injector. The formation of carbon deposits and deposits is inevitable, but poor fuel quality and long idle running of the engine will lead to nozzle blockage and acceleration.

The work of injector plays an important role in the power of each engine. Due to poor fuel, the injector does not work normally, resulting in serious carbon deposition in the cylinder; The accelerated wear of cylinder and piston ring will cause unstable idle speed, rising fuel consumption, weak acceleration, difficult start-up, excessive emission, complete blockage of injector and damage to engine.
