What are the effects of dirty fuel injectors on cars?

When the fuel injector is slightly blocked, it will also have a certain impact on the vehicle condition. Sometimes there will be such failures: put in first gear, start, the car shakes a little, and when you put in high gear and accelerate, this phenomenon disappears again. If the various sensors on the car work normally, the throttle body has also been cleaned, and the circuit It’s normal, it is likely that the fuel injector is slightly blocked. However, when accelerating in a high gear, the slight glue may be sprayed away (dissolved) again, and the performance of the car is restored. Such a slight blockage of the injector generally does not need to be cleaned. Because the slight gelatin can be dissolved away. Therefore, running at high speed often can reduce the formation of carbon deposits. If the fuel injection nozzle is not cleaned for a long time, the clogging phenomenon will become more and more serious, which will cause poor fuel injection, poor fuel injection angle and atomization, resulting in engine idling, acceleration or full load Poor work in working conditions will reduce engine power, increase fuel consumption, increase emission pollution, and even make the engine unable to work. Therefore, it is necessary to clean the fuel injectors regularly. If the nozzles are not cleaned for a long time or cleaned frequently, it will have a bad effect. As for the frequency of cleaning, it should be determined according to the condition of the car and the quality of the fuel used in normal times. Generally speaking, most car owners are now advised to clean at about 20,000 to 30,000 kilometers. If the car is in good condition and the fuel quality is good, it can be extended to about 40,000 to 60,000 kilometers.
