Why should EFI vehicles pay attention to the cleaning of fuel injectors?

Because the injector works well, it plays a fundamental role in the power of each engine. Poor fuel will lead to poor fuel injectors, serious carbon deposition in cylinders, accelerated wear of cylinders and piston rings, unstable idle speed, rising fuel consumption, weak acceleration, difficult start-up and excessive emissions.

Therefore, the nozzle should be cleaned, but frequent and excessive cleaning of the nozzle will also cause bad effects. The frequency of cleaning should be determined according to the condition of the car and the quality of the fuel usually used. Generally speaking, most car owners now advocate cleaning within the range of 20 thousand to 30 thousand kilometers. The car is in good condition and the fuel quality is good, which can be extended to about 40-60 thousand kilometers.

Extended data:

When the injector is slightly blocked, it also has a certain impact on the vehicle condition. Sometimes, there will be such a fault: the car is a little shaky when it starts in first gear, and it disappears when it accelerates in high gear. Assuming that all kinds of sensors on the car are working normally, the throttle is clean and the circuit is normal, it is likely that the fuel injector is slightly blocked.

However, when accelerating in high gear, slight gum may be sprayed away (dissolved) again, and the performance of the car will be restored. This slight blockage of the fuel nozzle can usually be avoided. Because slight gum can be dissolved. Therefore, in daily driving, you should always run at high speed to reduce the possibility of carbon deposition.

If the fuel injector is not cleaned for a long time, the blockage will be more serious when the gasoline quality is poor or the vehicle runs for a long time, resulting in poor fuel injection, poor fuel injection angle and atomization, poor engine performance at idle speed, acceleration or full load, reduced engine power, increased fuel consumption, aggravated emission pollution, and even made the engine unable to work.

Therefore, the nozzle should be carefully cleaned and inspected regularly to ensure its good work.
