Dirty air filters can cause symptoms such as insufficient intake and insufficient power; Idle speed will be unstable.
Let's talk in detail about these two hazards:
One is insufficient intake and insufficient power. When the air filter becomes dirty, the intake resistance increases, and the above symptoms occur when the engine does not receive enough oxygen. If damaged, it will accelerate engine wear and reduce engine life.
Secondly, if the air filter is dirty and lacks oxygen, resulting in incomplete combustion, it can cause black smoke, a large amount of carbon accumulation in the cylinder, blackening of the oil, and loss of lubrication effect. From the perspective of engine wear, this will greatly increase the wear rate and fuel consumption.
The function of an air filter is to purify the air entering the engine. For its maintenance, it mainly involves cleaning and replacing.
Generally speaking, after driving 7500-8000 kilometers, it is necessary to clean and maintain the air filter. Of course, the environment is different in each region. It is particularly mentioned here that when there is a lot of dust, the maintenance cycle should be shortened accordingly.
